    摘要: The specification is concerned with sealant compositions comprising prepolymers which are capable of being cured by atmospheric moisture. The compositions provide a desirable blend of properties with regard to application and use, using prepolymers derived from comparatively inexpensive raw materials. The prepolymers correspond to a reaction product of an at least substantially linear acrylate ester polymer having a Tg of not greater than 10.degree. C. with a hydrolysable silane having a saturated organo-functional group, the reaction product being a fluid material soluble in organic solvents and curable by exposure to atmospheric moisture to a resilient solid. The prepolymer is a silane-modified polymer which preferably has from 2 to 3 hydrolysable silane groups per molecule of prepolymer and from 1 to 3 hydrolysable groups per silane group. Preferred acrylate ester polymers are homo- or co-polymers of butyl acrylate; copolymers may contain other acrylate monomers and or may contain up to 50 wt % vinyl monomer e.g. styrene. Preferred silanes are amino-silanes particularly those having 2 or 3 hydrolysable alkoxy groups. Also described and claimed are methods of making the prepolymers. The compositions are suited for construction and glazing sealants.

    摘要: A two-component system for forming a sealing composition for bonding to unsanded, polymer-coated fiberglass surfaces. The system includes a resin component containing a major amount of epoxy resin, glycidoxy silane (0-2.5 wt. %) and hydrophilic-modified polyolefin fiber (0.5-10 wt. %), and a curing agent component having a major amount of amine curing agent and which may also contain amino silane (0-5 wt. %). The resin component may also contain alpha-phase alumina (20-80 wt. %), ceramic fiber (2-25 wt. %), and mica (2-20 wt. %). In another formulation, the resin component contains glycidoxy silane (0-2.5 wt. %), hydrophilic-modified polyolefin fiber (0.5-10 wt. %), ceramic fiber (2-25 wt. %), anti-foam material (0.2-1.0 wt. %), and epoxy novolac resin to 100 wt. %. The curing agent component contains amino silane (0-5 wt. %) and amine curing agent to 100 wt. %.
