Improves the adhesion of our Colourants to leather & vinyl. Adhesion Promoter is a polyurethane liquid with extraordinary adhesive properties. Applied to leather or vinyl one step before the application of colourant, the product creates a flexible coating that binds to the leather surface.
About Adhesion Promoter
Rust-Oleum® Adhesion Promoter is a fast drying, clear primer that helps paints adhere to polyolefin surfaces such as automotive plastics, vinyl, trim, bumpers, fiberglass and more.
Filler Prep Adhesion Promoter helps filler stick to plastic. It's necessary when applying fillers to TPO and polypropylene parts, like most late model bumper covers. Filler Prep allows the filler to get a good "bite" on the plastic and eliminates the peeling problems common on many automotive plastics.
Any plastic made from Thermoplastic Polyolefin is inherently difficult to paint. Because adhesion is difficult, all Olefin parts must be sprayed with an adhesion promoter, which will allow the plastic and a coating applied over it to coalesce, or fuse together.
Although it isn't necessary to use adhesive promoter on a daily basis, it is a valuable tool to have on-hand for certain installs. Adhesive promoters increase the adhesion power of vinyl by about 5x.
Adhesion promoters, or surface modifiers, are extremely important when making some types of adhesive plastic repairs. If the adhesion promoter is not applied when required, or applied incorrectly, the repair will fail. (although there are some exceptions because some plastics do not require adhesion promoters).
Plastic Categories: Thermoset and Thermoplastic
Plastics that melt are known as thermoplastics. These plastics are semi-rigid and typically require an adhesion promoter.
The most important thing to remember when you're spray painting plastic is to start with a good primer to prevent the paint from peeling or chipping.
Yes you could but the adhesion promoter would be best used after the primer is applied and prepped. Adhesion promoter for your base coat. Adhesion promoter is made to paint stick if you use a good primer you shouldn't have any problems with the primer.
In medical and pharmaceutical applications, adhesion promoters are typically applied to the surface of the substrate before the adhesive or coating is applied.
Dry and recoat times are based on 70°F and 50% relative humidity. Allow more time at cooler temperatures. Dries to touch in 10 minutes and dries to handle in 15-30 minutes.
But adhesive promoters increase the likelihood of pulling the paint off the car if the PPF has to be removed, so we prefer the old-fashioned method of waiting.
Gloss paints are the easiest for vinyl to adhere to, while matte paints are the most difficult. In the past few years, paint manufacturers have come out with paints that resist dirt and grime and are easy to clean.
Plastic primer, also known as plastic adhesion promoter, is a product that is mainly intended to optimise the adhesion of subsequent coats of paint, such as putty or filler paint, to the surface.
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.
Sealer & Adhesion Promoter (aerosol)
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.
There is too much moisture in the air, and as a result, the solvent has a hard time leaving the paint – and you get stickiness. Imagine you have a wet towel, and you want to dry it out – would you throw it in a full bathtub? No, you'd place it out in the fresh air, allowing the moisture to evaporate.
Acrylic and latex paint are two of the highest-quality paints for vinyl due to their thick application and water resistance. The best part is that vinyl spray paint adheres not only to vinyl but to wood and even a plastic surface like PVC.
Luckily, Majic Paints Diamond Hard RePurpose Interior/Exterior Satin Paint brushes on smoothly and evenly over most surfaces, including plastic, without need of sanding or priming. The durable, scratch-proof finish doesn't fade, and it is suited to interior or exterior use.
If the paint isn't sticking to the plastic, the problem is usually that the surface is too glossy. Thoroughly sand the plastic to a matte finish for best results. Keep the spray light to avoid drips. An initial tack coat of about one-third to one-half coverage will help later coats stick better.
3M Adhesion Promoter 111 is generally a first choice for painted surfaces and bare metals. This promoter works on a wide variety of paints and bare metals, the primary exception is textured paints and rough metals where effectiveness can be lower.
Do you need to prime plastic before painting? It depends. If you're using a spray paint for plastic then you can skip the priming step. But if you're using regular old spray paint (which isn't recommended, but we get that sometimes it's just what you have), then definitely use a plastic primer spray first.
Keep the can upright and start spraying before the primer passes over the part – this way you'll ensure an even finish across the entire substrate. Apply 3-4 coats of primer and wait for 15 minutes between coats to ensure each layer has dried sufficiently.
