MAXGUARD GN // H/S 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. MAXGUARD GN // H/S premium gelcoat surfaces are hard, glossy and tough and they are highly resistant to UV-radiation, gloss deterioration and hydrolysis.
