Color high-quality spray or hand lay-up gel coat, suitable for ship model bathtub top glass fiberglass

Gel coat is made of unsaturated polyester (UP) adding pigments and thixotropic agents to disperse fiberglass reinforced plastics (FRP) and countertop paints to develop colored thixotropic products.

instruct:
1. Select the appropriate type of gel coat before use.
2. Thoroughly prepare the mold, the surface of the mold determines the surface of the product.
3. Stir the gel coat well before use, but the speed should be slow to avoid bubbles from stirring.
4. Before starting work, keep the gel coat and mold temperature at 16°C-30°C, and the ideal mold temperature should be 2°C-3°C higher than the gel coat temperature. This results in a smoother gel coat surface after curing.
5. The relative humidity in the workshop should be less than 80%, and the humidity will lead to the required curing temperature. In addition, it is necessary to prevent water accumulation on the surface of the mold.
6. The surface of the mold should be filled with wax, do not use release wax containing silicon. Water-soluble mold release wax must wait for its water to evaporate before applying gel coat.
7. Do not dilute with solvents, such as acetone. Small amounts of styrene (<2%) can be added if lower viscosities are required.
8. The amount of curing agent (MEKP) is generally 1-2%. If the amount of curing agent is too high or too low, the water resistance and weather resistance of the product will be reduced.
9. Wait for the color paste to ensure uniform and stable color. Accurately weigh the recommended amount and mix using low shear equipment. You can also use colored gel coats.
