Aluminium filled tooling epoxy resin

  • Excellent heat conductivity
  • Casting & lamination resin system
  • For demanding curing & thermoforming cycles
  • High modulus & mechanical properties

RESOLTECH 2060 ALU 25 aluminum epoxy resin is formulated for the production of composites tooling using it as casting resin or as wet layup lamination system. It enables the production of tooling that will resist many years to the most demanding heating and cooling post-curing cycles of: heating RTM & pre-preg tooling, thermoforming of thermoplastics or polymer concrete/solid surface injection tools.

The heat conductivity of this resin system is twice better than a conventional epoxy resin, meaning that the dwell temperature at which a part must be post-cured will be achieved in half the time on tools manufactured with this resin system, improving the tool productivity.

This new generation system, optimized with excellent self levelling characteristics and excellent air release, is suitable for the manufacture of large composite tooling. It should be applied by brush or casted.

The 2060 ALU 25 system is also available in a thixotropic version, the 2060T ALU 25 & a gelcoat version the 2060GC ALU which are recommended also for manufacturing of tools incorporating heating elements as the system is heat conductive but not electrically conductive.

Final thermo-mechanical properties will be obtained after a post curing cycle defined according later in this technical data sheet. It is possible to de-mould tools from plugs without pre-cure, enabling the use of cheap plug materials - and guaranteeing the dimensional stability of the plug and the mould.
