Painting Plastic Car Parts

Painting Plastic Car Parts can be divided into hard plastic (ABS plastic for body, fiberglass, etc.) and soft plastic (PP, PU, etc.) according to the softness and hardness of plastic products. Whether or not Painting Plastic Car Parts needs plastic primer depends on the situation, if there are bare plastic products, plastic primer should be sprayed. For parts that have been primed, spray the intermediate or top coat directly during processing. For parts without primer, either hard or soft, they should be sprayed with a special plastic primer or covered with a vinyl wash-type coating to improve their surface adhesion.

Painting Plastic Car Parts' painting characteristics are different between internal and external plastic parts painting: internal plastic car parts are generally painted with semi-glossy or completely non-glossy paint, by participating in a certain proportion of leveling agent in the paint; external plastic parts are either painted with non-glossy or glossy paint, depending on the specific situation.


Most automotive top coats and medium coats can be used for spraying plastic parts, including two or three-process metal top coat coatings. However, before painting, it is best to first determine if the topcoat chosen is suitable for the particular plastic substrate and if soft additives and special plastic primers are to be used. For some special plastic parts, such as interior plastic parts, soft tops, etc., special spraying treatment and special coatings are often required.
