Abstract: Gelcoat compositions comprising a base resin, a reactive diluent component, a pigment and more than about 2% by weight inorganic extended fillers wherein the reactive diluent component either a) comprises styrene and one or more alternative reactive diluents or b) consists of one or more alternative reactive diluents. Also, disclosed is watercraft made with these gelcoat compositions. Further, a process for making gelcoat compositions is disclosed wherein some or all of the styrene in the reactive diluent component is replaced with one or more alternative reactive diluents.

Abstract: A two-part acrylic structural adhesive comprises a first package containing from about 10 to about 90 percent by weight of at least one ethylenic unsaturated methacrylic ester selected from the group consisting of 1) an alkyl mono-, di- or tetra-substituted cyclohexyl methacrylate, wherein the substitutions occur in either the 3, 4, and/or 5 ring positions, and 2) a linear or branched C4–C10 alkyl methacrylate; from about 10 to about 80 percent by weight of a toughener, and an adhesion promoter; and a second package containing a bonding activator, and, optionally, an epoxy resin.

Abstract: Disclosed are internally blocked borates useful for polymerizable compositions, and polymerizable adhesives made therewith. The internally blocked borates have general structures: wherein X represents —CHR6—, oxygen or sulfur; n is an integer; R1, R2, R3, R4, R5, and R6 are independently selected, for example, from unsubstituted and substituted C1-C10 alkyl, alkylene groups, or aryl groups, including other embodiments further defined, and M is a counter ion with positive charge m.

Abstract: A method for bonding together two substrates that includes applying to a first substrate an adhesive composition that includes (a) a trifunctional olefinic first monomer, (b) an olefinic second monomer that is copolymerizable with the first monomer and (c) a free radical initiator and then contacting a second substrate to the composition-applied first substrate so that the first and second substrate adhesively bond together. There is also provided a method for providing a coating on a substrate that includes applying to the substrate a composition that includes (a) a trifunctional olefinic first monomer, (b) an olefinic second monomer that is copolymerizable with the first monomer and (c) a free radical initiator and then allowing the composition to cure.

Abstract: A polymer having at least one reactive terminal or pendant functional group that has been capped with a trifunctional olefinic compound. The polymer can be made by contacting a base polymer having at least one reactive terminal or pendant functional group with a trifunctional olefinic compound under conditions effective to react at least one of the terminal or pendant functional groups with the trifunctional olefinic compound. The capped polymers are particularly suitable as crosslinking toughening agents in multi-components compositions such as adhesives, coatings and matrices for composites.
