摘要

"The composition of copolu00ecmero - polisiloxano not cured, process for formation of a composition of polisiloxano, sealant, sealant and substrate coated with a composition of high elongation.A low modulus of 100% comprises a copolymer dispersed in a continuous phase polisiloxano.The copolymer is made up of large quantities of at least one monomer is capable of forming a polymer of low Tg and relatively small quantities of at least one monomer is able to formA polymer of high Tg.The monomer to form the polymer of low Tg may be an alkyl acrylate as the monomers which are the high Tg polymer can be an ester chloride.A crilonitrila or derivatives thereof, a vinyl substituted with aromatic such as styrene, an alkyl methacrylate, and the like.The composition has good adhesion to substrates as well as good aging by viscosity and can be used in calafates or sealants.
