Structural Epoxy Foaming system

Density 250 kg/m3
Optional post-curing
Excellent mechanical properties


RESOLTECH 2080 M25 / 2084M - 2085M is a liquid foaming epoxy casting system formulated to produce low density, closed cell, strutural cores.

This system has a (free) expansion coefficient of 4, enabling the production of 250 kg/m3 epoxy foam. 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 with no conforming moulds without alteration of the dimensions of the composite.

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

The main advantages of this epoxy foaming system 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
