Each 2.5cc packet delivers a measured dose of the same chemistry found in 3M 6396, optimized for substrates such as TPO, PPO, PP, PC and PC\/ABS blends. The formula is UV-detectable, helping verify application coverage under inspection lights, and the small packets make it easy to carry and apply without dispensing equipment.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adhesion promoter improve bond reliability on low-energy plastics?\u003c\/h3\u003e\n\u003cp\u003eThe 4298 primer modifies plastic surfaces to increase wettability and create a better surface for tapes and adhesives to grip.
