scope:

This specification details the properties and requirements of a solvent based adhesion promoter that is designed for use on raw reaction injection molding (RIM), and flexible paint systems used as the topcoats for RIM and/or thermoplastic olefin (TPO) fascias and bumper covers.

Material Description. The adhesion promoter is an air dry system that can be applied with a pressurized flow gun, brush or similar applicator. The product is utilized as a means to increase the short term (quick tack) adhesion of foam pressure sensitive adhesive tapes used to mount insert strips, moldings, and other components.

Symbols. Not applicable. 

Applicability. Tape-attached components bonding to RIM or flexible paint systems. 

Remarks. The application surface must be clean, dry and free of foreign matter. Contaminated surfaces should be cleaned with a dry, untreated lint-free cloth and an alcohol/water or naphtha wipe. The promoter should be applied in a thin, uniform coat on the surface to be activated. Allow for thorough drying (1 to 3 minutes) prior to applying the tape. Tape should be applied within one hour for best results.
