Product description

EX-1543 cyanate ester film adhesive has been formulated for use in specific applications where low moisture absorption and / or low dielectric constant and low loss are of the utmost importance. Furthermore, the preceding benefits do not come at the expense of adhesion properties. EX-1543’s strength and toughness when bonding solid, honeycomb, or foam core structures are comparable and often greater than high performance epoxy adhesives, especially at elevated temperatures.

Due to the cyanate ester resin system’s inherently low shrinkage during cure, bonded structures will retain less inherent stress and will therefore remain dimensionally stable during thermal cycling. This factor is of extreme importance when bonding structures for use in space. Finally, like other cyanate ester based products, EX-1543 film adhesive displays low outgassing and microcracking properties to assure structural integrity even after severe environmental exposure.
