The Ultimate Plastic Paint Bond: Secrets To Success

what is the best bonding paint for plastic

Painting or gluing plastic can be challenging due to its smooth and non-porous surface. Different types of plastics require different types of adhesives or paints. For gluing plastic, the type of plastic must first be determined, as this will dictate the type of adhesive required. For instance, plastics in categories 1, 2, 4, and 5 are very difficult to glue, while category 6 plastics can be bonded with poly cement, epoxy, or cyanoacrylate (super glue). When it comes to painting plastic, it is important to use a paint specifically designed for plastic, as this will ensure better adhesion and coverage. Some recommended paints for plastic include ColorBond spray paint, Krylon Fusion All-in-One, and Rust-Oleum Painter's Touch 2X Ultra Cover spray paint.

Whether you're updating your car interior, refreshing restaurant seating, or giving new life to old plastic furniture, ColorBond LVP delivers professional-grade results with ease.

Different types of plastic and their glues

Plastic is an extremely flexible and durable material, but its smooth and slippery surface makes it difficult to glue. The best glue for plastic depends on the type of plastic you are working with.

There are eight recycling codes for plastic, which indicate the exact material the product is made of. Items stamped with a 1 are made from Polyethylene Terephthalate (PET), while 2 means High-Density Polyethylene (HDPE). 3 is used for Polyvinyl Chloride (PVC), 4 means Low-Density Polyethylene (LDPE), 5 represents Polypropylene (PP), 6 is for Polystyrene (PS), 7 indicates other plastics, including polycarbonate and acrylic, and 9 is used to represent acrylonitrile butadiene styrene (ABS).

Plastics in categories 1, 2, 4, and 5 are very difficult to glue. For polystyrene (category 6), you can use a poly cement, epoxy, or cyanoacrylate adhesive. For polycarbonate (category 7), an epoxy will work best, while acrylic requires an acrylic solvent adhesive. For ABS plastics (category 9), an epoxy or cyanoacrylate glue will work well, although ABS solvent adhesives are also available.

Some common adhesives that can be used for gluing plastic include PlasticWeld, a two-part epoxy, and Amazing GOOP, an all-purpose adhesive. Loctite also offers a range of adhesives formulated to work well with plastic, including their Plastics Bonding System, which offers a delicate application.

When it comes to bonding paint for plastic, there are several options available.
