Product description

TC4015 cyanate ester film adhesive has been formulated for use in specific applications where low moisture absorption and high temperature bond strength is important. The resin system’s strength and toughness when bonding solid, laminate, honeycomb, or foam core structures is comparable, and often greater, than high performance epoxy adhesives and polyimides 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, Toray’s TC4015 film adhesive displays low outgassing and good microcracking resistance to assure structural integrity even after severe environmental exposure.
