Dowsil 738 is a one component, RTV silicone rubber formulated for continuous use in temperatures ranging from -62 to 180 degree Celsius. The innovative silicone rubber has good dielectric properties and is easy to handle with no heating or mixing. It also provides easy repair by cutting away the older used material and applying a fresh new one. Dow 738 complies with the non-corrosive requirements of MIL-A-46146 Type I. The UL listing for service temperature is 180 degrees Celsius where elongation is not vital. 738 will for a bond to most clean surfaces including glass, metals, silicone and vulcanized rubber. Bond strength will differ and be inconsistent unless a primer is used. The electrical sealant will begin to skin over in approximately 20 minutes at room temperature. The curing time will be about 24 hours at room temperature and 50 percent relative humidity to a depth of 70 mils. The curing time will depend on the thickness of the material and it will cure inward from the surface into the middle. Dowsil 738 sealant is supplied in 90 ml tubes, 10.01 fl oz cartridges and 4.5 gal pails.
