Product Description
Meets AMS-S-7124
CS3201 is a two-part, polysulfide based compound which cures at room temperature to a flexible, resilient rubber with excellent adhesion to aluminum, titanium, stainless steel, steel, magnesium, and other materials. Proper mixing of CS3201 is assured by the contrasting colors of the two parts. CS3201, Class B is a thixotropic paste which is easily applied with an extrusion gun or spatula, but will not flow from vertical or overhead surfaces. The cured sealant is resistant to aircraft fuels, lubricants, oils, water, and weather, and remains flexible at low temperatures.
Surface Preparation
To obtain good adhesion, remove all traces of oil, wax, grease, dirt, or other contamination. This is done by wiping with a clean oil free solvent.
Mixing Instructions
To 100 parts by weights of Part A add 10 parts by weight of Part B. Mix well to uniform consistency.
Application
CS3201, Class B may be applied with a pressure gun or a spatula. Specified application lives are based on the standard conditions of 77F and 50% relative humidity. Higher humidity will reduce the application life. Lower temperatures or lower humidity will extend the application life. For every 10F rise the application is reduced by one half, for every 10F drop, it is doubled.
