Jul 17, 2020

In fact, in the glass fiber reinforced plastics industry, gel coat resin is the topcoat on the surface of the product, generally known as gel coating. Because the matrix is still unsaturated resin, it is mixed with color paste and various additives, so some people call it gel coat resin or polyester gel coat, mainly used as the decorative surface of the product.

In fact, in the glass fiber reinforced plastics industry, gel coat resin is the topcoat on the surface of the product, generally known as gel coating. Because the matrix is still unsaturated resin, it is mixed with color paste and various additives, so some people call it gel coat resin or polyester gel coat, mainly used as the decorative surface of the product. Let's follow the editor to see what its precautions are!

1. Avoid direct sunlight during storage of the gel coat coating. The temperature should be below 25, and the gel coat should be stored separately from MEKP.

2. The construction area of the pretreatment mold and gel coat coating should avoid dust. The glue coating should be poured into a clean bucket.

3. When mixing the curing agent or color paste, do not mix too much air.

4. Do not use high-shear mixing equipment. Otherwise, the thixotropic index will drop, the color paste will separate and accumulate, gel coat flow and bubbles will occur.

5. It is strictly forbidden to pour the color gel coat directly on the mold and brush it directly.

6. The gel coat time cannot be adjusted too fast, which is not conducive to the escape of bubbles.

7. The amount of curing agent should be appropriate, the amount of curing agent can be checked by measuring the gel time.

8. Do not use silicone release wax, they will produce fish eyes.

9. The use of methyl ethyl ketone with good quality, low water content, medium active oxygen content and poor curing agent quality will seriously affect the performance of the gel coating.

10. Do not add accelerants on the color gel coat layer, so as not to affect the color.

11. The good performance of the gel coat coating can only be fully reflected after it is fully cured. Qualified customers should post-cure the product.

The above is the relevant precautions about gel coat resin introduced this time, I hope I can help you.
