In the automotive and aerospace industry, adhesive sealants are used in a variety of ways. EXS-110, Exonic fuel-resistant room-temperature-vulcanizing (RTV) silicone is a superior fuel-resistant sealant. This fuel-resistant sealant is typically used as an aftermarket adhesive sealant, in place of gaskets, for assembling and repairing field systems and tanks, or where gaskets or seals are necessary that do not conform to conditions or shapes that a regular gasket can withstand.
The fuel-proof sealant is a black paste that is set in eight minutes, tack-free in 20 minutes and fully cured in 72 hours. The oxime cure system is a one-part noncorrosive fuel-resistant RTV with a tensile strength of 300 PSI, elongation of 260% and peel strength of 40 PPI. This highly viscous fuel-resistant silicone paste has outstanding adhesion to non-primed surfaces, including metal, plastic and glass. EXS-110 is resistant to swelling effects from fuels, solvents and oils, as shown through only 25% swelling after seven days of submersion in fuel at room temperature.
Specially formulated for superior fluid resistance, this Silicone based gasketing compound withstands extreme temperature changes without loosing it's flexibility. Suitable as either a gasket maker that seals surface imperfections between metal parts and is ideal in high performance applications. This compound resists common engine fluids, including oil, gasoline, ethanol, water and anti-freeze and prevents contamination from moisture and dust.
