Sicomin Surf Clear EVO epoxy system is:
- specially formulated for the manufacturing of surf boards.
- suitable for hand lay up of glass, carbon, aramid, natural and synthetic fibers.
- compatible with all commercial foams: polystyrene, polyurethane, cross-linked & linear PVC foams and others.
- compatible with all typical fillers used in the surf Industry.
Characteristics:
High mechanical performance epoxy system recommended for surfboard production.
Yields surfboards with a flexible touch, high temperature and UV stability.
High surface and' plug finishing, for high gloss requirement.
Other applications: surf repairs, fin boxes & plugs, pattern and model coating, etc...
Low odor and reduced skin aggression for a better work environment.
Hardeners:
3 hardeners EVO are available with the same mixing 2 / 1 ratio by volume.
- Medium hardener is designed for big boards or high ambient temperature applications (over 35 °C).
- Fast hardener is designed for classic boards In mild temperature working conditions (around 20"C).
- Super-Fast hardener is designed for fast lamination, gloss and repairs or low temperature application conditions.
Advices for application:
Work in a clean environment with heating facility.
Ideal working temperature from 18 °C to 30 °C.
Maintain a constant temperature during lamination.
Avoid high ambient humidity.
Avoid exposure to U.V. during the cure. Laminates and coatings benefitting from a sun free post cure or polymerized for at least 7 days at 18°C will obtain greater U.V. resistance and mechanical properties
Do not dilute with solvents. Please consult our technical assistance.
The use of compatible pigments is possible.
Keep packaging well-sealed as hardeners are sensitive to carbonic gas and humidity.
A polyurethane or other top coat paint can (for best UV protection) be applied, without primer, after sanding the final
layer of Surf Clear EVO.
*SICOMIN Is heavily involved in green chemistry. When technology and availability of raw materials allows, we choose
raw materials from biomass sourcing. Surf Clear EVO epoxy resin is manufactured with a green carbon content of 40 %.
*Hardeners react with carbon dioxide and moisture. Need to be kept in its original closed container. Avoid to a maximum any contact with air. If the aspect becomes cloudy, do not use.

Fast Hardener
Really happy with Sicomin Fast hardener, cant compare to Medium one, but this one works really great. At the beginning I was a bit affraid of kinda short potlife (about 8mins) to laminate bigger boards (I did 7.0 biggest until now) as I do usually multicoloured tinted lam jobs, but there is no reason to be affraid at all. In Combination with Additive EP217 and SA 300 Accelerator, it works amazing for the seal/gloss coats and if the timing is ok I can make coats on both sides in one day, which was not possible with epoxies I used before.
