What types of gel coat resins are there:

At this stage, the gel coat resins produced in China can be divided into ortho-benzene type, ortho-benzene (neopentyl glycol type, isophthalic type, isophthalic) neopentyl glycol type and vinyl ester type according to the types of conventional resins; it can be improved Glass fiber materials, improve the appearance quality of unsaturated polyester resin-based carbon fiber products, and maintain the solid layer of materials that will not be corroded by external natural environmental substances. Decoration design and maintenance of solid layer, gel coat resin.

1. M-phenylene neopentyl glycol type: The conventional resin of m-phenylene neopentyl glycol type gel coat is neopentyl glycol/isobenzoic acid unsaturated polyester. The structure of the resin grants it excellent physical properties and aging resistance, and is especially suitable for gel coat resins where weather resistance and abrasion resistance are high.

2. Isophthalic type: The conventional resin of isophthalic gel coat is isophthalic unsaturated polyester resin, which has high tensile strength, ultra-high temperature resistance, corrosion resistance and oxidation resistance. It is suitable for making glass fiber reinforced plastic products and glue. Clothing resin.

3. Ortho-phthalic type: The conventional resin of ortho-phthalic gel coat is ortho-phthalic unsaturated polyester resin, which has good weather resistance, moisture resistance and impact resistance. It is suitable for higher standard FRP products and gel coat resins.
