Claim:
1. A method of binding an anchor pin to a borehole formed in a substrate, comprising the steps of: placing a cartridge, slug or package of anchoring adhesive in the borehole, the anchoring adhesive including a first part A and a second part B separate from each other and present in separate capsules; wherein the first part A and the second part B are present in a weight ratio of about 1:4 to 40:1; driving an anchor pin into the borehole, rupturing the capsules and causing the first part A and the second part B to mix together; and chemically reacting the first part A and the second part B in a space between the anchor pin and an inner surface of the borehole, forming a strong adhesive bond between the anchor pin and the inner surface of the borehole; wherein the first part A prior to the chemical reaction comprises an isocyanurate compound and a vinyl ester compound in combination and the second part B comprises a free radical initiator, and the chemical reaction comprises reacting the isocyanurate compound with the vinyl ester compound; wherein the first part A comprises about 1-30% by weight of the isocyanurate compound, about 3-50% by weight of the vinyl ester compound, zero to about 40% by weight of one or more additional monomers, and about 20-70% by weight of one or more fillers; wherein the adhesive bond exhibits an adhesive tensile strength of at least about 1500 psi, a compressive strength of at least about 10,000 psi, and shrinkage not greater than about 1.6%.
