0.39 kg Epoxy Hardener SD Surf Clear MEDIUM EVO

SD Surf Clear MEDIUM EVO Epoxy Hardener

Hardeners:
2 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).

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.
