Product Description
Meets AMS-S-8802C, Type II
CS3204 is a fuel resistant sealant for use on integral fuel tanks and pressurized cabins as well as other areas subject to contact with aircraft fuels, lubricants, oils, water and/or weathering.
CS3204 is a two-part polysulfide base compound which cures at room temperature to a flexible, resilient rubber with excellent adhesion to aluminum, magnesium, titanium, steel, and numerous other materials. CS3204 is designed to withstand the attack of sulphur compounds that are present in jet fuels. CS3204 Class B is a thixotropic paste that will not flow or sag on vertical or overhead surfaces.
Surface Preparation
To obtain good adhesion, the surfaces must be free of all traces of oil, wax, grease, dirt or other contamination. Working in small area segments, wipe the surface using a clean rag doused in an oil free solvent.
Mixing Instructions
Too 100 parts by weight of Part A add 10 parts by weight of Part B. Mix well to uniform consistency.
Application
The work life of CS3204 is indicated by the number following the class designation and varies from 1/2 to four hours. Work life is the minimum amount of time the material will maintain its application properties.
