3303 Gel Coat Resin Water chemical corrosion impact resistance

short description:

Gel coat resin is a special resin for making the gel coat layer of FRP products. It is a special type of unsaturated polyester. It is mainly used on the surface of resin products. It is a continuous thin layer with a thickness of about 0.4 mm.The function of the gel coat resin on the surface of the product is to provide a protective layer for the base resin or laminate to improve the weather resistance, corrosion resistance, wear resistance and other properties of the product and give the product a bright and beautiful appearance.

PACKING AND STORAGE

• Packing of gel coat resin: 20 kg net, metal drum

NOTE

• All information in this catalog is based on GB/T8237-2005 standard tests, only for reference; maybe differ from the actual test data.
• In the production process of using resin products, because the performance of user products is affected by multiple factors, it is necessary for users to test themselves before selecting and using resin products.
• Unsaturated polyester resins are unstable and should be stored below 25°C in a cool shade, conveyance in refrigeration car or in nighttime, averting from sunshine.
•Any unsuitable condition of storage and conveyance will cause the shortening of shelf life.

INSTRUCTION

• 1102 gel coat resin does not contain wax and accelerator, and contains thixotropic additives.
• The mold should be processed in a standardized manner before preparation to meet the requirements of gel coat construction.
• Color paste recommendation: special active color paste for gel coat, 3-5%. The compatibility and hiding power of the color paste should be confirmed by field test.
• Recommended curing system: special curing agent for gel coat MEKP, 1.A2.5%; special accelerator for gel coat, 0.5~2%, confirmed by field test during application.
• Recommended dosage of gel coat: wet film thickness 0. 4-0. 6tmn, dosage 500~700g/m2, gel coat is too thin and easy to wrinkle or expose, too thick and easy to sag
crack or blisters, uneven thickness and easy to rise Wrinkles or partial discoloration, etc.
• When the gel coat gel is not sticky to your hands, the next process (upper reinforcement layer) is made. Too early or too late, it is easy to cause wrinkles, fiber exposure, local discoloration or delamination, mold release, cracks, cracks and other problems.
• It is recommended to choose 2202 gel coat resin for spraying process.
