NOTE

All information in this catalogue is for informational purposes only and is based on GB/T8237-2005 standard tests and may differ from actual test data.

Since the performance of the user's product is affected by many factors, the user needs to self-test before selecting and using the resin product during the production process of using the resin product.

Due to the instability of unsaturated polyester resin, it should be stored in a cool place below 25 ° C, refrigerated truck or transported at night, avoiding the sun.

Shelf life may be shortened due to inappropriate storage and shipping conditions

INSTRUCTION

• 33 gel coat resin does not contain wax and accelerator, but contains thixotropic additives.
• The mold should be treated in a standard manner before use 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%. It is 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 reveal the bottom; too thick is easy to sag, crack or blisters; uneven thickness is easy to rise Wrinkles or partial discoloration, etc.
• When the gel coat gel is not sticky to your hands, the next step (upper reinforcement layer) is made. Too early or too late, it is easy to cause wrinkles, fiber exposure, local discoloration or delamination, white mold release, cracks, cracks and other problems.
• For those with higher weather resistance or heat resistance requirements, it is recommended to choose Chebi isobenzene-neopentyl glycol 1102 gel coat resin or 2202 gel coat resin.
