ULTRAVIOLET LIGHT INHIBITORS
United States Patent 3666713
Title:


Abstract:
Ultraviolet light absorbers with extremely low volatility are prepared by reacting 2,4-dihydroxybenzophenone and organic dihalides or diepoxides. The resultant compounds have the general formula ##SPC1## Where R is a divalent organic radical. These compounds may be used as carriers for dye, permitting the internal coloring of polyester films and fibers.

BACKGROUND OF THE INVENTION

Such polymeric materials as plastics, rubbers, coatings, colorants, and particularly thermoplastic polymers, are photochemically degraded by exposure to terrestrial sunlight, fluorescent lights, and other sources of ultraviolet (UV) radiation, especially in the 300-370 nanometer wavelength. Accordingly, it has long been common practice to blend into thermoplastic polymers minor amounts of such UV inhibitors as o-hydroxybenzophenones, 2-(2'hydroxyphenyl) benzotriazoles, substituted acrylonitrile and salicylates. Such inhibitors are believed to function by absorbing a high percentage of the damaging radiation and converting the absorbed energy to heat, or some other harmless wavelength.

Although the o-hydroxybenzophenones and their derivatives impart little or no color and are considered effective in counteracting the effect of UV radiation in the 290--380 nm range, their utility has heretofore been limited. For example, the comparatively high temperature employed in processing polyester film and fibers tends to "smoke out" (i.e., volatilize) any UV inhibitor included in the polymer. The volatilized inhibitor not only is wasted, but also is unpleasant for workers in the vicinity and tends to both corrode and contaminate the processing equipment. To minimize this problem, benzophenone inhibitors are often incorporated in a composition which has a lower melting point than polyester and coated on the surface of oriented film, even though this technique greatly reduces the chelating antioxidant effect of the inhibitor. Even when it is applied in this way, the inhibitor tends to evaporate or sublime when exposed to elevated temperature and/or reduced pressure, e.g., when incorporated in or on plastic equipment used in space vehicles, satellites, etc. Further, it is difficult to adhere such coatings adequately, especially when the coated film is subjected to rough handling. Coating techniques are generally unsuited for work with fibers.

SUMMARY

The present invention provides novel UV stabilizers which have all the advantages of benzophenone compounds without the disadvantages discussed above. Compounds made in accordance with this invention have extremely low volatility, thereby facilitating their use in commercial equipment, where "smoking out" is effectively eliminated, even at comparatively high temperatures and/or low pressures. Compounds of this invention can be tailored to specific situations required; e.g., the melting point can be adjusted to virtually any desired range.

The foregoing advantages are achieved with compounds of the formula ##SPC2##
nice try this is not for window film.

ST. PAUL, Minn 3M announced today that the National Fenestration Rating Council (NFRC) has certified a range of the company's window films. These films include 3M's metal-free Prestige Series, which blocks 66% of the sun's heat streaming through windows and 99.9 percent of the ultraviolet rays. NFRC certification affirms 3M's films meet rigid energy performance factors for windows and doors and for attachment systems. Information about NFRC's labeling program can be found at http://www.nfrc.org/

"Affirmation of the quality of 3M Window Films is one of the things customers seek at a time when ways to increase commercial and residential energy savings are top of mind for consumers," said Michael Hassenauer, 3M Window Film.
(Looks like the film on this list is certified by the NFRC )

Everything I see from here and on other sites is from 2006 so I found this it is from 2008.it looks better than the others about specs.

i was an authorized mmm dealer and authorized with the other mannys.. i use to get most of my bids. film wasn't an issue, the amount of money i wanted make was. i use to look at the clients home, their decor, the area they lived at and could base what they can afford. presented them film that exceeded their criteria at an acceptable price. if a client wanted mmm i knew i'd make double, if they wanted prestige, vs70 or vk70 i'd make triple.

i know mmm didn't make the best film nor the best anything, but i don't see why not use them for what they have to offer.

look@ luminous efficacy(spectra select)
vk70 and vs70 are 1.4. again, better then presitge.

sorry for acting like a new guy but>>>> whats wrong with 3m tint??

Read the 255 posts before yours.......................

Is a .05 difference really worth the trouble of having to edge seal?

Apparently for some it is the Anti Christ, the source of everything that ills our society today.

nothing and everything it depend how you view things.


and rdymn if your competing against them it would matter. when your clients pays up to $---/sqft. they want the better film, unless they just want the name.

i personally don't like installing any Ag film for corrosion. but you have to do what the clients ask you you lose.

Mike IM guessing you pulled these from old drawers there at the 3M headquarters. Are you still repping for 3M? Would I know you from my old days when I worked for the 3M distributor in Dallas?

Think about this....why put that there? It is not accurate whatsoever and they know it and put that there. So, they are a proponent of pushing false information. If you wish, not smoke and mirrors, but giving the general public a false sense that the product may do something it really may not. Put simply, if you know it cannot be an accurate result and it shows such a high savings (they are using results on the highest end of the range) why would it be there, other than to mislead the consumer???

We can argue semantics all day long, but if other manufacturers did this, all 3m dealers AND others would be railing them also.

I always find it interesting that one very important spec. is always missing on those pages... Solar ABSORBTION!
Go ahead and try to find it...

i used 3m film back in 99-2000 alot of security film s35 or s50 4 mil and 8 mil film it sucked ass cause alot of the rolls of film had what 3m call bullets in the film. as costly as 3m is it not worth the hassel

what 3m called a bullet was it looked like a air bubble in the film but was hard to the touch and you didn't know when use the security film it was going to pop up and how many was going to be in the roll they had thousand of rolls that had this they told me here in florida warehouse it was manufacturing problem

i had many many many feet of film replaced by 3m

To answer your questions that would be a NO and a NO and a NO. It is that I just got inspired as I read the SELF PROMOTION that V4V posted in post #210 and I must say my finger got very tiered scrolling down and down. That thing is like a small novel. So I am researching all that I can regarding anything pertaining to window film. And I seen a few things posted here so I did some checking found a few things and I posted them.thats all and I am not on here to support any one film manufacturer in particular as I stated early on in this thread that I apply all types of films.

The specs are from the front and back of a film sample card. Do you need the solar absorption % for this film?That is a good question as most others have it posted I wonder why they don’t.

I have a hard time believing this thread is still alive & basically saying the same thing as the first 2 pages... So MMM isn't the best film on the market...SO WHAT!!!

It has name recognition & most homeowners are more comfortable w/ this film being used on their home & most are willing to pay a little extra to get it. MMM uses this same approach to dealers, it's called "Business 101". As a business owner I actually try to turn as large of a profit as I actually can. If I go against 3 other tint shops on an estimate & we all use the same film, guess what? The homeowner goes w/ the cheapest!

However, if we all match in personality & reputation then it would be nice to have something in your arsenal to put you ahead of the pack. It's called "Business 101" guys...

Most homeowners? Rarely do I come across a customers who asks for MMM. I dont carry it b/c I dont trust the longevity. I want happy customers for years to come, thats my "business 101".

lets just say that the huge 3M logo on my ads get them to ask about it

If you are referring to me I have been busy and do not get on this site. Took a lng weekend. It is a holiday ya know.

Not for sure but from my memory I believe Vista specs are rated with 1/8" glass and 3M's are 1/4" so that will change the performance.

Regardless of all you guys bickering. Who on here does large installs? PJE???? or something like that.
Need an install of upto 20K sq ft installed. Please pm me

If you have a lifetime warranty why are you worried about longevity. I have seen plenty of the favorites on here fail.

I can agree with that




Do you still make the same on warranty work than you would selling it for the first time? Thats why. Doing warranty work is very time consuming. Id rather use a film I know will last 16-20 years instead of a film I feel will only last half that, and from a mfg that mainly deals with making and developing window films. This is just my take on it.

who really cares what the manufacture gives as a warranty? It is worth about as much as the paper it is printed on. Yeah, if they approve the warranty work you will make something, but that consumer and anyone they talk to now has a lower opinion of window film as the film they have has failed.....

I am on the "kill the lifetime warranty" train though so....

Thats what I meant to say...

yes... and show them with the meters as well. on a side note i make it a point to tell them about the near infrared 1000nm range. for most you should be talking greek.

I have never had a warranty not approved. So not sure what film you use that you have issues getting it approved. All films fail. I have had Llumar fail in 3- 5 years and some last 15 years

actually its 6000 times smaller than a human hair.

i would say 1 out of a thousand could understand what you telling them. that means 999 dont really care. thats a classic case of over selling. romancing the custy is one thing, smothering them with too much info can be bad for closing sales.

tomtint and vclimber, thanks for the props. between us we have more years invested than most of our competition has been alive. as long as you fly straight you will last in this business. seems some on here could use a lesson on that one.

No I disagree. It is not the same thing as the first 2 pages.

Spreading misleading and false information is what has been discussed. Why can't it just stop and everyone compete off of sound factual information? The auto industry has always suffered from the sales tactics of auto dealers... let's not let that kind of conduct continue in the window film industry. We're better than that.

I have more questions... brb

Case in point. Here is a link that arrived in my e mail.

Incredible, The ammt of complete garbage on that site is just par for the course

you know, after reading these posts and having been with many different manu's. you have to have a new out look on the way you present your product to the custys. as many years as i have been selling film i still learn from people and there ideas on how it should be. case in point, vc's cage match with the film disty on the vs70 thread. there were comments made on both sides that were relevent selling points that i in all my years in this industry havent thought of using.

Cage match? man you crack me up dryshrinker...

I'm up for a fresh new outlook... how do we get all of these ppl to change their ways?

Good luck on that one. As long as a dealers manufacturer continues to spew falsehoods, so will the dealer.

I said I had more questions and...well... what can I say?

From the New 3M Ceramic Card:

"* Performance data generated for a typical film on
6mm glass using applicable industry test methods
and standards. Infrared rejection measured from
900nm – 1000nm. "



I'll quote PM... "Here we go again!"

my info card has no IR rejection value. it does however say 900 t0 1000 nm. ive done a few installs with it and so far so good. good for autos as well.

Check the interior side:

CM 50= 68%
CM 40= 78%
CM 30= 84%

I thought they'd learn from the Prestige fiasco... guess not.

Kind of reflective for autos don't you think?

yeah, we use cm40 on the cars. so far custys like the look/view. the performance is pretty good as well.

heres some CM in action.
mercedes with CM40 (thats the owner in the white shirt)


a condo with CM30


a house with CM 40. this house was featured in a home design magazine.


the bottom 3 from left to right and the top 2 from left to right are done.

I thought it wasn't going to be released until November? Did you pre-order?

You get a lot of those "owners" bringing their cars in. I remember the news gal photo...

No doubt, 45% or lighter for single ply ceramic... anything darker is just too reflective. Stuff works good...

lol, thats how we roll...

no pre order. a month or so its been available. prestige dealers only, non prestige auto dealers are limited to 20 and 40" rolls only.

you mean this one... elita loresca. she's in LA now. i still have her cell #.

That's the one

I'd hit it.............

All this 3m stuff has me curious of a few things. Please PM me if you are a 3m automotive film dealer. Thanks.
