Hardener 1077

Fast curing clear epoxy system

  • Clear laminates and topcoats
  • Very fast hardening in film
  • Excellent wetting properties
  • Can be top coated with polyester without inhibition

RESOLTECH 1070 CLEAR / 1077 is a crystal clear epoxy laminating system formulated to produce clear laminates and high gloss coatings with good mechanical properties while retaining some flex for improved fatigue performance such as for surfboards.

The 1070 CLEAR / 1077 system is formulated for professionals who manufacture surf, wind-surfs, kiteboards, or any composites parts with high-end finish aspects requirements — and that need a very fast hardening system, closer to polyester curing speeds for improved productivity.
The wetting out properties of this system and air release are acclaimed for and it has no sensitivity to blush unlike other surfboard resin systems that need extra additives for an equal performance or for improved sandability.

The resulting laminates will be absolutely clear on carbon fibre and even transparent if applied on special glass fabrics such as Hexcel TF970 treatment. The viscosity is adapted for squeegee, or brush application, and provides a perfect bubble free surface due to its surface tension properties.

The system has been formulated in order to leave virtually no free amines on the laminate. This enables the use of any quality polyester finish coat for quick sanding on top of the laminate without inhibition of the polyester.

RESOLTECH 1070 CLEAR / 1077 will cure at room temperature and obtain 90% of its mechanical properties after 5 days at room temperature. Post curing will elevate the final TG like any other epoxy system.
