Description
20 mil (0.020″) clear acrylic foam high bond tape supplied in 108 ft (36 yd) rolls. Alternative to 3M VHB 4905.
Chem-Set VST3050C is a double sided acrylic foam tape designed for bonding transparent materials including glass, acrylic, and polycarbonate. The thinner profile provides a clean bond line with less gap fill compared to thicker tapes, while maintaining strength and long term durability.
The viscoelastic acrylic core distributes stress and compensates for thermal expansion between dissimilar materials, improving long term bond reliability.
