JS-GN SERIERS are premium gelcoats based on a special isophthalic/NPG resin. The base resin and the gelcoat formula are optimized to give final products excellent mechanical and weathering properties. JS-GN SERIERS premium gelcoat surfaces are hard, glossy and tough and they are highly resistant to UV-radiation, gloss deterioration and hydrolysis.

It is highly recommended that all materials are stored at stable temperature under 25 °C preferably indoors, and away from direct sunlight. A high quality methyl ethyl ketone peroxide (MEKP) catalyst should be used between 1.5 – 2.5%. The gelcoat with the catalyst must be gently stirred before taken in use. The material should be used within 5 months from the date of manufacture. Prolonged storage or storage outside of recommended conditions can influence gelcoat liquid properties like viscosity and gel time and it is recommended to test these properties before starting application.
