BLUE FIN systems have been specifically developed for the production of EPS core epoxy surfboards. They are fast curing, low viscosity, water white and hard wearing when cured. Both the BLUE FIN 20 and BLUE FIN 25 systems have accredited minimum biocarbon contents and comply with the requirements of Sustainable Surf .
Both BLUE FIN 20 and 25 are two component systems, with a 2:1 by volume mix ratio with the hardener. There are two hardeners with different reactivities (fast and regular) which can be mixed in any proportion to tune the reactivity to the customers’ requirement. BLUE FIN FAST is commonly used alone unless ambient temperature is above 30°C. The minimum biocarbon content for both BLUE FIN 20 and 25 systems is unaffected by the choice of fast or regular cure speed hardener.
