  • TG 102°C with 2062 hardener

RESOLCOAT 2060 GC ALU / 2061S & 2066H epoxy gelcoat is formulated for the production of composites tooling. It enables to manufacture tooling that will resist many years to the most demanding heating and cooling post-curing cycles of: heating RTM & pre-preg tooling, high output heat forming of thermoplastics or polymer concrete/solid surface injection tools.

Its novolac based formula guarantees the highest mechanical and chemical resistance, notably to styrene. Polyester or vinylester parts manufactured on the 2060 GC ALU gelcoat will release with high gloss for numerous cycles. Should the gelcoat needed to be repaired, polishing the repaired area will enable to regain a high gloss surface aspect.

This new generation system, optimized with excellent self levelling characteristics and excellent air release, is suitable for the manufacture of large composite tooling. It can be applied by brush, roller or airless while guaranteeing low toxicity working conditions to the users.

The recommended application thickness ranges from 500 µm to 600 µm at 23°C, which it is possible to achieve in one coat on a vertical surface without sag.

Final thermomechanical properties will be obtained after a post curing cycle defined later in this technical datasheet.
