Applications of 2080 M25 for Casting and FoamingApplications of 2080 M25 for Casting and Foaming


Hardeners 2083M & 2085M

Structural epoxy foaming systems

  • Final density of 250 kg/m3
  • Can be released from the mold without post curing
  • TG up to 110°C
  • Excellent thermo-mecanical properties
  • Hydrophobic and rot-proof

RESOLTECH 2080 M are liquid foaming epoxy casting systems formulated to produce low density, closed cell, strutural cores. Those systems have a (free) expansion coefficient from 4.5 to 6.6, enabling the production of 170 and 250 kg/m3 epoxy foams.

The slow, controlled foaming reaction makes un-necessary the use of mixing machines like with PU foams. The low pressure of the foaming will enable direct casting in the final parts without conforming moulds and without alteration of the dimensions of the composite.

This system is available in black or white (to be pigmented with any RAL pigment paste available on request).

The main advantages of those epoxy foaming systems over existing systems are :

  • No brittle stage after the foaming, making it un-necessary to cure before releasing from
  • mould or to post-cure depending on the mechanical characteristics needed
  • Perfect compatibility with prepregs and epoxy resins even during their polymerization
  • Excellent resistance to water
  • Major improvement of thermal and mechanical resistances compared to existing epoxy foams
  • Homogeneous structure of the foam
  • No VOC emission
