EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of WSS M2P188-B1 testing. This specification defines performance requirements for decorative coatings, including paint, soft coat paint and scratch resistant interior coatings, on plastic surfaces for indoor use.
In general, plastics used in the automotive industry are highly elastic and flexible, these parts have the ability to regain their original shape without being deformed and broken.
For example, if you were to do the same for a plastic part and a sheet metal part, the plastic part's lack of deformability in the event of an impact would cause the paint to crack or split.
To avoid this problem, there are products and paints for plastic that are specially adapted to provide the paint finish with greater elasticity, while offering better performance under pressure and mechanical compression after an impact.
Another factor to consider is adhesion. Plastic materials have their own polarity and surface tension, making it difficult for paint to adhere correctly to the surface.
It should also be noted that in order to optimize the adhesion of paint to a plastic surface, it is necessary to carry out a thorough degreasing and cleaning beforehand.
Although plastic does not rust like metals, it can deteriorate after prolonged exposure to atmospheric agents (UV rays, moisture), chemicals (fuels, oils, detergents) or mechanical agents (abrasion, scratches).
Although color loads with high pigment concentration can be added during the manufacturing and molding process of the plastic, due to the very properties of the material, this color will not be able to reproduce the same shine and shade as sheet metal parts.
Therefore, the finish color should be applied to achieve the best color reproduction and matching of plastic and sheet metal parts.
