Can acrylic be painted? How to spray? Will there be any bad phenomenon? Yes, you need to spray a layer of plastic mesh primer and then topcoat.
The adhesion of the acrylic material itself is very poor. If it is sprayed with ordinary industrial paint, cracks will easily occur, because ordinary paint is more versatile for metal substrates, but it is used on acrylic substrates. Adhesion is relatively not very strong.
The method to prevent the cracking of the acrylic substrate spray paint, only need to spray the special primer for the acrylic substrate. The primer is sprayed on the substrate before spraying the top coat. The main purpose is to increase the adhesion of the acrylic substrate, so as to solve the problem of spray paint Cracks appear later.
Extended information: performance characteristics, characteristics:
1. It has crystal-like transparency, the light transmittance is above 92%, the light is soft, the vision is clear, and the acrylic colored with dyes has a good color development effect.
2. Acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.
3. Acrylic sheet has good processing performance, which can be thermoformed or mechanically processed.
4. The transparent acrylic sheet has a light transmittance comparable to that of glass, but the density is only half of that of glass. Also, it is not as brittle as glass, and even if broken, it will not form sharp shards like glass.
5. The wear resistance of acrylic sheet is close to that of aluminum, with good stability and corrosion resistance to various chemicals.
