High temperature structural epoxy film adhesive suitable for the bonding of aluminium and composite or to honeycomb core materials. Good combination of honeycomb peel strength and high service temperature when co-cured with HTM® and certain MTM® prepreg systems. Type: film | Out Time (days): 30 | Temp: N/A | Cure Flex: N/A | Process: autoclave, Vacuum | Peel Strength: N/A | Shear Strength unit N: N/A

HTM110 series prepregs are high temperature resistant, inherently flame-retardant, cyanate ester matrices suitable for initial cure at 180°C (356°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. HTM110 series autoclave processing prepregs are high temperature cure variants of Solvay’s LTM110 and MTM110 matrices. HTM110 series prepregs are selected for applications where longer work life is important and where it is essential to have cure compatibility with other 180°C (356°F) cure materials.

HTM® 131 is a clear cyanate ester resin formulated to provide excellent surface finish with a high level of mechanical performance retention at elevated temperatures. It also offers a good balance of out life, cure speed and ease of handling. DMA E' onset Tg of 400°C (752°F). Flexible cure between 135°C and 180°C (275°F and 356°F). Available on a wide range of reinforcements.

HTM® 556 is a controlled flow, toughened bismaleimide (BMI) matrix system offering improved handling characteristics and after an appropriate post-cure, thermal cycling capability up to 250°C (482°F).
HTM® 556 has been developed for structural applications where continuous service temperatures exceed 200°C (392°F).
