Solvay LTM® 110 series Ester Resin System
Categories: Polymer; Thermoset; Polyester, TS
Material Notes: Description: LTM110 series pregregs are high service temperature cyanate ester resin system capable of initial cure at temperatures as low as 70°C (158°F). After a suitable post-cure, the glass transition temperature can be increased to a maximum of 330°C (626°F), thus allowing components to withstand short duration thermal spikes up to this temperature. LTM110 series component pregregs have be specifically developed for applications where the best dimensional stability is required over a wide temperature range, and where tooling suitable for high temperature autoclave curing is not available.

Features & Benefits:

  • 3 days tack life at 21°C (70°F)
  • 6 months storage at -18°C (0°F)
  • 70°C (158°F) initial cure
  • Autoclave cure
  • Good dimensional stability and thermal durability up to 250°C (482°f) after post-cure
  • Maximum Tg of 330°C (626°F); can withstand thermal spikes to 330°C (626°F)
  • Inherently flame retardant, with low toxic gas and smoke generation
  • Good dielectric properties for radar transparency
