SikaBiresin® L323

SikaBiresin® L323

SikaBiresin® L323 is an epoxy-based, composite tooling compound designed for the construction of tools, jigs, models, sandwich structures and other tooling or modeling applications. When mixed the system results in a very pliable elastic compound which can be applied to the tool surface without crumbling or cracking. SikaBiresin® L323 can be applied at any thickness above ¼" without excessive exotherm. Tools constructed with SikaBiresin® L323 maintain a very high degree of dimensional stability, are light in weight, and can be machined as well as drilled and tapped. The SikaBiresin® L323 resin and harder are both syntactic dough compounds, which minimize splash hazards, in comparison to standard, room temperature epoxy laminating systems.

  • Colored resin and hardener for mix indication
  • Pliable and formable with no cracking or crumbling when mixed
  • Can be machined or drilled and tapped
  • Low density (lightweight)
  • Very low coefficient of thermal expansion (CTE) for excellent dimensional stability
  • Low exotherm build
