RESOLTECH 1900/1903 is an epoxy system recommended for high thermo-mechanical parts/ molds manufacturing.

Specially formulated for large composite structures manufacturing, 1900/1903 system offers a long working time that enables thick laminations while avoiding high exothermic reactions.

Thanks to its low viscosity and high wetting properties, it can be used with any reinforcements, however, due to its excellent thermo-mechanical properties, it is recommended for high modulus carbon fibers laminations.

This system has excellent cross linking properties and enables to release parts from plugs even after a low post curing of 8h at 60ºC. Final thermo-mechanical properties will be obtained after a suitable curing cycle.

With its high TG (138°C), 1900/1903 is suitable for both tooling and parts manufacturing that must withstand temperatures up to 120°C (prepreg molds).

Available in thixotropic version 1900T/1903T for vertical application.
