What are the precautions for producing FRP resin? Do you know? Today, let’s take a look! The spraying quality of FRP resin gel coat directly affects the appearance quality, weather resistance, water resistance, and chemical media corrosion resistance of the product, so it is necessary to Strictly control the application of gel coat.Things to note are as follows: 1. When configuring the fiberglass resin gel coat, mix it thoroughly, especially when using different pigment pastes. If the mixing and distribution are uneven, some spots and streaks will appear on the surface of the product, which will not only affect the appearance of the product but also reduce its quality. Physical properties: Stir evenly when adding the curing agent to avoid surface wrinkles, cracks and other defects caused by uneven curing.2. You can use a brush or a special spray gun to spray glue.If the viscosity of the gel coat is too high, an appropriate amount of styrene can be added to adjust the viscosity and make up for the styrene lost by volatilization during the operation, but the amount of styrene added must be controlled according to process requirements.3. The thickness of the fiberglass resin gel coat layer is controlled at 0.3~0.5mm
