CS 3201 Class B-4
Integral Fuel Tank and Cabin Sealant
Gallon Kit (96 oz.)
CS 3201 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 CS 3201 is assured by the contrasting colors of the two parts. CS 3201, 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.
