0543 Polysulfide Adhesive
Resistant to fuels, oils, lubricants, water & weather
0543 is a one‐component, grey, thermally conductive, precision mixed, degassed, and frozen polysulfide adhesive. A fuel resistant material that is flexible when cured, 0543 is compliant with HMS 16‐1985, Compound II, Class 2, Grade 1. 0543 can be cured at either room or elevated temperatures. This material is thixotropic when applied and features a very low glass transition temperature as well as having a thermal conductivity of 0.7 (W/mK). It has a long pot life of 2 hours and is an ideal fillet material. Along with fuels, 0543 is resistant to lubricants, oils, water, and weather and adheres well to most metals.
