UV resistant adhesive
PREP G Bostik Inc.

Prep G is a "black out" primer to be used on glass, polycarbon (PC) and acrylic glass (PMMA) without ceramic coating (frit) before dispensing the glazing 70-08A, 70-11, and 70-12 adhesives.
Prep G provides ultraviolet light protection to the bond line. Note: UV protection is required for all direct glazing (windshield and windscreen) bonding applications. Factory applied frits provide UV protection.
Prep G must be used on glass that does NOT have ceramic coating (frit) and must be APPLIED BEFORE the glazing adhesive. Read and follow instructions in the Technical Data Sheet.
