Patent ID: 8235251

Claim:
A two-part cartridge comprising one dispensing unit comprising a first composition comprising (A) 10-15% b.w. of the total composition of a solid carboxylated butadiene-nitrile rubber, (B) 40-60% b.w. of the total composition of a monomer blend comprising a) 10-90% b.w. based on the total weight of the monomer blend of tetrahydrofurfuryl methacrylate; b) 5-80% b.w. based on the total weight of the monomer blend of at least one monomer selected from the group consisting of 2-ethylhexl methacrylte, 2-ethoxyethyl methacrylate, cyclohexyl methacrylate, isobornyl methacrylate, isooctyl acrylate and isooctyl methacrylate; and c) 0-70% b.w. based on the total weight of the monomer blend of at least one monomer selected from the group consisting of isobutyl methacrylate, n-butyl methacrylate, cyclohexyl acrylate, n-hexyl methacrylate, isodecyl methacrylate and isodecyl acrylate (C) 25-35% b.w. of the total composition of a meth(acrylated) polyurethane and (D) 2-10% b.w. of at least one type of core shell particle, and a second dispensing unit comprising a second composition comprising at least one compound capable of inducing polymerization of said first composition.
