This journal article describes properties and uses of silicone seal adhesives. Used mainly in the construction and manufacturing industries, (for bonding, gasketing, glazing, sealing, repairing, etc. ) these easy-to-use one-part, room-temperature vulcanizing (RTV) liquid rubbers adhere to most common substrates including metals, glass, ceramics, wood and painted surfaces, have excellent dielectric and electric properties, and are strong, resilient, flexible and durable, despite exposure to harsh weather and environmental conditions. Some sealants were developed for specific qualities - eg. low viscosity, noncorrosive and odorless curing, fuel and chemical resistance, tear strength, paintability, etc. Six basic types are described: 1) general purpose, 2) noncorrosive (non-acid) cure (eg. for corrosion - sensitive electrical and electronic equipment), 3) low viscosity (self-leveling), 4) fluorosilicone (eg. for aircraft and automotive parts exposed to harsh chemicals and solvents, 5) low-modulus, high performance (eg. for precast concrete, excessive joint movement), and 6) paintable sealants which can be coated with oil or latex paints.
