Applications & Uses

Application Method

Do not over-mix gel coats. Over-mixing breaks down gel coat viscosity, increasing tendencies to sag, and cause styrene loss, which could contribute to porosity. Gel coats should be mixed once a day for 10 minutes. The gel coat should be mixed to the sides and bottom of container with the least amount of turbulence possible. Air bubbling should not be used for mixing. It is not effective and only serves as a potential for water or oil contamination. Do not add any material, other than the amount of recommended methyl ethyl ketone peroxide, to this product without the advice of a representative of CCP Composites Korea.

Technical Details & Test Data

Cure

It is recommended to recheck the gel time in the customer's plant because age, temperature, humidity and catalyst will produce varied gel times.

Storage & Handling

Handling and Storage

Uncatalyzed, this gel coat has a usage life of 120 days from date of manufacture when stored at 23°C or below in a closed, factory-sealed, opaque container, and out of direct sunlight. The usage life is cut in half for every 15°C over 23°C. Totes of product can have even shorter usage life (66% of the drum shelf life mentioned above).
