Applications of 1500 for Injection Moulding / RTM and InfusionApplications of 1500 for Injection Moulding / RTM and Infusion


Hardener 1504

Structural Epoxy infusion system

  • Thermally stable up to 140°C (284°F) when fully post cured
  • Resistant to thermal cycling damage
  • Low initial mixed viscosity for easier infusion; 250 cP at 23°C (73.4°F)
  • Long pot-life and gel time; capable of infusing large or complex moulds
  • Ambient curing and low shrinkage for accurate mould manufacture

RESOLTECH 1500 / 1504 is an epoxy infusion system with an extremely low viscosity that enables structural composite parts & tools manufacturing with glass of carbon fibre.

The system is compatible with RESOLTECH´s range of 140°C tooling gelcoat, laminating and repair systems.

RESOLTECH 1500 / 1504 is a low shrinkage ambient curing system, which provides a simple way to produce high accuracy moulds. Thanks to its low viscosity and its exceptional wetting ability this system is designed for infusion and cures at ambient temperatures, it should then be mid-cured at 60°C (140°F) for 8 hours to guarantee the strength needed for demoulding.

It can then be post cured off the plug to give a material that is thermally stable up to 140°C (284°F).

Like all RESOLTECH systems, 1500 / 1504 is a state of the art chemistry epoxy system, formulated without any CMR components and caring about the H&S working conditions.
