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 .
There are two BLUE FIN systems, BLUE FIN 20 and BLUE FIN 25. The BLUE FIN 20 system has a guaranteed minimum biocarbon content of 20% when cured. Surfboards produced using the BLUE FIN 20 or BLUE FIN 25 system automatically qualify to carry the Sustainable Surf ECOBOARD LEVEL ONE label.
The BLUE FIN 25 system has a guaranteed minimum 25% biocarbon content when cured. It is certified by the US Department of Agriculture (USDA) and the material is labelled as such. Surfboards produced using BLUE FIN 25, which also comply with minimum plant based or recycled content in the core, qualify to carry the Sustainable Surf ECOBOARD GOLD LEVEL label.
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.
