Product Description
Product Name: Gelcoat HS-NC **** S/H Series
1. Brief Introduction:
HS-NC****S/H Gelcoat is an ISO/NPG type gel coat, which matrix resin is isophthalic acid / neopentyl glycol unsaturated polyester, and it is pre-promoted. The structure of the matrix resin endows the gel coat with good mechanical properties and weather resistance, so this gel coat is especially suitable for the fields with high requirements of weather resistance and water resistance. "****" represents the color number.
2. Product Features:
-Excellent impact resistance;
-Very high surface gloss;
-Excellent water resistance and weather resistance;
-Excellent high temperature resistance and corrosion resistance.

Note:
1) The method of preparing the cast is performed according to ISO5893;
2) Curing system:1.5% Cobalt isooctanoate (0.6%), 1.5% AKZO M-50;
3) Post-cure:room temperature×24h+60ºC×3h+110ºC×2h.
4. Application Notes:
1) Choose the appropriate color gelcoat model according to product needs and application environment.
2) Mix the gelcoat in bucket gently before use, avoid excessive high shear rates and avoid air entrapment during mixing.
3) Ideal application temperature should be between 18-25°C and humidity less then 80%. Mold should be polished and clean before gelcoat application.
4) The curing agent used for gelcoat is MEKP(the dosage is generally 1-3%). If the amount of the curing agent is too high or too low, the water resistance and weather resistance of the product will be reduced.
5) Total gelcoat film thickness should be between 600-800μm. It is recommended to apply 100-150μm in the first pass and wait for 2 minutes before application of following layers.
6) Obtain total gelcoat thickness in 2-4 layers with 700-800 g/m2 gelcoat. Check gelcoat thickness with gelcoat thickness gauge.
7) Correct application pressure for spray type gelcoats and film thickness is very important to prevent sagging of wet gelcoat film.
8) Minimum 2 maximum of 4 layers of gelcoat application is recommended for Brush type gelcoats.
9) Check gelcoat cure degree before starting lamination layers. Press your finger for 30 seconds on gelcoat film to check cure degree. When you do not see gelcoat residue on your finger but gelcoat to remain sticky on the film, you can continue with lamination layers.
5. Storage:
1) To ensure stability and maintain optimum performance, the gel coat should be stored under 25 ºC in a sealed manner and away from heat sources, such as direct sunlight or steam pipes. It should be stored separately from oxidizing substances, peroxides and metal salts.
2) Transportation should fit the State Council "Chemistry Dangerous Articles Safety Management Regulations". Because it contains styrene monomer, it is hazardous and inflammable.
