3M 4298 Adhesion Promoter

3M 4298 Adhesion Promoter is formulated specifically for use with 3M VHB acrylic foam tapes to achieve a permanent bond with low surface energy plastics used for automotive dashboards, interior trim, and exterior trim applications. It works well with LSE plastics, as well as TPO, PPO, PP, PC, PC and ABS. 3M Adhesive Promoter is supplied in an easy-to-use sponge applicator packet, for a fast and precise application. Convenient to use, it dries within 30 to 90 seconds. Each sponge applicator packet contains .85 ounces (2.5 cc) of adhesion promoter, enough to cover up to 150 square inches. Since formulations and surface energies can vary for these types of materials, each application should be verified through testing. Product Applications Automotive instrument panel and interior trim Injection-molded side body side moldings Automotive claddings For use with 3M Acrylic Foam Tapes and 3M Acrylic Plus Tapes Country of Origin: United States.Application InstructionsThe liquid contents of the packet should be completely used as soon as possible after opening. Hold packet upright and avoid squeezing an opened packet to prevent spillage of liquid contents. The packet can be opened by tearing across the top of the packet at the notches. This will expose the sponge applicator. Do not remove the sponge or squeeze a freshly opened packet. Handling the bottom section of the packet should enable application of 3M adhesion promoter 4298 with no mess. Apply a thin, uniform coating to the bonding surface, using the minimum amount that will fully coat the surface. A wet coating thickness of 0.002 inches or less is recommended. Apply promoter only to areas that will be fully covered with tape. Although drying times may vary due to temperature and/or humidity, a drying time of 30 to 90 seconds is typically indicative of this thickness. The primer should be dry before applying tape. For best results, apply tape immediately after primer application or no more than one hour afterward. Be sure the primed surface remains free from contaminants prior to tape application.
