How do you use 3M 4298?

Apply thin, uniform coating to the bonding surface, using the minimum amount that will fully coat the surface. A wet coating thickness of 0.002 inch or less ensures a good application. Although drying times may vary due to temperature and/or humidity, a drying time of 30-90 seconds is indicative of this thickness.

What can be used as an adhesion promoter?

Mono- and diphosphate esters have been used as adhesion promoters in bonding acrylic adhesive on metals and as a primer for aluminum bonded with epoxy. Unsaturated acid phosphates have been used as primers on metals to be bonded with free radical adhesives.

How does an adhesion promoter work?

Adhesion promoters (AP) are bi-functional materials that increase adhesive strength between the coating and the substrate and sometimes are referred to as coupling agents. Unlike priming systems, adhesion promoters are generally applied at thinner film thicknesses.

Do I need to use 3M adhesion promoter?

Some of the must know applications of the 3M Adhesive Promoter Sponge includes improving adhesion bond to interior trim, exterior trim, instrument panel, and dashboard. Essentially, you want to use 3M Adhesion Promoter Sponges when you plan to use adhesive tape on a low surface energy material.

Is adhesion promoter the same as primer?

Although both products are great, they are not the same thing and can not be switched out for one another. 3M Automotive Adhesive Promoter can not be used as a primer on bare metal, and self-etching primer is not going to help you get 3M Acrylic Foam Tape to stick to low surface energy materials.

What does 3M adhesion promoter do?

Our 3M™ Adhesion Promoter 111 is a fast-acting, isopropyl alcohol based solution designed to promote better and faster adhesion of 3M™ VHB™ Tapes. This product works particularly well for adhering 3M VHB Tapes to high surface energy substrates like galvanized steel, bare metals, and painted surfaces.

Does adhesion promoter work on metal?

Bulldog® Sealer & Adhesion Promoter is the only one-component sealer and adhesion promoter for the auto body collision repair market that can be used on both primed and painted metal and plastic. Bulldog® seals these surfaces, offering fast dry times and excellent holdout, while filling scratches.

Do adhesion promoters need a primer?

You will need to apply an adhesion promoter or plastic primer to optimise the anchoring of the subsequent coats. Another option is to repair the plastic part. In this case, the part has lost the primer coat, so the adhesion promoter will have to be applied again to optimise the paint’s anchoring.

Can adhesion promoter go over paint?

Can You Spray Adhesion Promoter Over Paint? It is possible, but the adhesion promoter should be used after the primer has been applied and prepared. A base coat adhesion promoter. If you use a good primer, you shouldn’t have any problems with the adhesion promoter.
