Cyanate ester-based pressure sensitive adhesive

摘要

The pressure sensitive adhesive disclosed is based on a multifunctional cyanate ester component. Monofunctional cyanate ester components and structural modifiers are incorporated to tailor the thermal and mechanical properties. The presence of crosslinks in the cyanate ester-based system also enhances the solvent resistance. While many types of PSAs consist of multiple components, all contributing to one aspect of the PSA's performance, the cyanate ester PSA does not require the use of plasticizers or other additives to stabilize mechanical performance over a wide temperature range. The simplicity of the system eases processing and prevents the possibility of degradation of the material over time.
