The ATSP family of resins is built on crosslinkable aromatic polyester oligomers. These pre-polymers allow simplified processability in a high temperature thermoset and have extremely long shelf lifes with no need for refrigeration. The fully set materials have these features in common:
- Thermal stability – ATSP resins are stable in air to at least 350℃ and 425℃ in nitrogen.
- Low outgassing
- Access to ATSP’s Self-Bond adhesive process via bond exchange reactions intrinsic to the resin termed interchain transesterication reactions
