Extruded or Metalized

[Guest tintman72]

Do you guys prefer an extruded film or a metalzed film for new cars?

[wndotint]

I use both. I like the way extruded shrinks, but only time will tell if it truly is not going to fade.

When you speak in terms of extruded I will assume you are talking about the pigmented polyester that was introduced by a poly maker a few years back to everyone but their largest purchaser... extruded is how polyester is made, clear or tinted (with pigment).

Pigments are not affected by the sun as easily as many dyes would be.

It is difficult to add metal deposition to pig-poly. Not sure if any film maker using pig-poly has had any success to date. This is probably the reason others choose to stay with dyed poly.

names, we want names

Didn't you observe of late what putting truth and names together brings about?

Pigments are not affected by the sun as easily as many dyes would be.

for a simple guy like me, that sounds redundant. Pigment and dye are the same to me, but obviously in this industry they are not. I almost hate to ask Metint for an explantion. I'm getting to old to learn new things.

I'm guessing that pigment is added to the material as it is made, dye is a bath the material takes after it is made of course this is the 'layman's' explanation

Excellent Zrok...

Additionally:

Pigment

noun: dry coloring matter (especially an insoluble powder to be mixed with a liquid to produce paint etc)

Dye

noun: a usually soluble substance for staining or coloring e.g. fabrics or hair

ok . lemme throw a stab at this.

film is dyed in a colored solution of etheylene glycol (anitfreeze ???) ??

Comes outta dye bath and requires dryers to set the dye, and hopefully

it will be have dried enough to be considered a low solvent retention product

(isnt this why some films have a strong odor when the release liner is removed?)

Extruded films have the pigment added to the polyesther pellets,then are pressed into a thin film.

To say an extruded material wont fade or color change would be wrong.

Ever seen a plastic toy left outside for a couple of months? Fade city.

Names , I got names, just wondering if you can add any nomes I dont know of.

The theory is the film won't change color since the color is through the film. When it is dipped, the dye is on the exterior.

Personally I think a dye is a dye and will fade after time.
