Mold gel coat is a coating used on the surface of FRP composite products, providing a protective layer for the products, improving the weather resistance, corrosion resistance, wear resistance and other properties of the products, and giving the products a bright and beautiful appearance, which enhances the performance of the products. and improve the appearance play a double role.
Mold Gelcoat Features:
The quality of FRP products depends to a large extent on the mold. To improve the quality of the product, it is necessary to have a good mold. A good FRP mold must not only meet the accuracy of product dimensions, but also meet their structural mechanics according to product performance. performance and mechanical properties. In terms of appearance, there must also be a certain degree of finish, smoothness and uniform thickness. And all of this is closely related to the performance and application of FRP mold gel coat. As the name suggests, the mold gel coat is specially designed for the production of FRP molds. Compared with the gel coat used for ordinary products, it should have the characteristics of high hardness, heat resistance, wear resistance, good polishability, high brightness, and long service life. Mold gel coats mainly include isophthalic mold gel coats and vinyl ester mold gel coats. Mold gel coats with superior performance should not only look at strength, but also consider heat resistance and mold release performance (including whether it is easy or not). Demoulding, whether the product is easy to demould after it is made into a mold), surface gloss, gloss retention rate, sandability, etc.
