All You Need to Know About Glass Frit
Frit is an industrial term for paint applied around automotive glass parts. One of the main ingredients in frits is glass-ceramic particles that blend with the glass surface making it a very durable and scratch-resistant surface.
Frit has two roles on the glass. First is used to hide the details of interior trim and pinch weld. The initial model vehicle uses wide prints to obscure the area that should be open.
Because the prints are smaller until they are not present in some models, the frit has a greater role in covering the unfinished area of the vehicle. Second, frit inhibits UV degradation from urethane adhesives. You can also check COE 96 glass frit via online sources.
Although the frit will not completely block UV light from passing through the glass, this frit significantly reduces UV light transmission. Most urethanes are UV unstable. If urethane is left exposed to sunlight for a long time, the urethane will turn yellow and change lime. The presence of frits will extend the life of the urethane adhesive system.
Frit is applied to glass using the silkscreen method. This is very similar to the method used for silk screen printing T-shirts. Frit design drawings developed for glass in the form of bent or curved. Then the image is opened and leveled. The silkscreen is made to allow the frit to pass through the gap in the screen.
