The result is said to be a unique, flowable liquid form fluoroelastomer that is highly versatile and keeps its elasticity even at -50[degrees]C (-58[degrees]F), which is said to be much lower than conventional fluororubbers.
7,220,487 B2 Lord Corporation has received a patent for an ambient temperature curable coating composition in a mixture of two-parts providing a nonvolatiles content of from 4-25% by weight, and comprised of a part A which is comprised of an organic solvent and fluoroelastomer dissolved therein, the fluoroelastomer containing crosslinkable sites in quantitative amount according to an acid number of from 2-6 mg base per gram, and a part B comprised of an organosilane comprising hydrolyzable groups and a mono primary amine, wherein the ratio of amine equivalents in part B to acid equivalents in part the A ranges from 3:1 to 12:1 and wherein a cured unsupported film from the coating exhibits at least 200% elongation.
00 Hardcover TA455 This guide to fluoroelastomer chemistry, processing technology, and related applications explains fluorocarbon elastomers, their character, properties, developmental history, and uses in addition to monomer characteristics and synthesis, polymerization, production, cure systems, processing, fluid resistance, and safety and disposal.
Because today's high-performance engines run hot and long, automotive fluids, such as oil and coolants, are said to need increasing amounts of amine stabilizers that can damage FKM fluoroelastomer seals.
