0720 Polysulfide Adhesive
Fuel-resistant, flexible when cured
0720 is a one‐component, grey, thermally conductive, precision mixed, degassed, and frozen polysulfide adhesive. It is fuel resistant material that is flexible when cured and is compliant with HMS 16‐1985, Compound V, Class 3 and HP 16‐103, Type VII, Class 3 specifications. 0720 can be cured at either room or elevated temperatures followed by a room temperature cure. This material is thixotropic when applied and features a very low glass transition temperature as well as having a thermal conductivity of 0.8 (W/mK). It has a long pot life of 2 hours and is an ideal fillet material. Along with fuels, 0720 is resistant to lubricants, oils, water, and weather and bonds well to most substrates including aluminum, magnesium, titanium, and steel.
