Abstract
An anchoring adhesive includes effective amounts of an isocyanurate compound and a vinyl ester compound that react and cure to form a composition having high compressive strength, high tensile strength and low shrinkage. The anchoring adhesive can be used to firmly bond anchor pins to boreholes in concrete, steel, wood, and other substrates.
Claims20
An anchoring adhesive, comprising:
- a first part A and a second part B present in a weight ratio of about 1:4 to about 40:1;
- the first part A comprising an isocyanurate compound and a vinyl ester compound;
- the second part B comprising a free radical initiator.
An anchoring adhesive comprising:
- a first part A and a second part B in a ratio of about 1:3 to about 30:1;
- the first part A comprising an isocyanurate compound and a vinyl ester compound;
- the second part B comprising a free radical initiator;
- wherein the isocyanurate compound is selected from the group consisting of compounds having the following chemical formula:
- wherein each R and R′ is allyl, alkyl or aryl;
- and the vinyl ester compound is selected from the group consisting of compounds having the following chemical formula:
- R4—OR3—O—Ar—R—Ar—OnR3—O—R4
- wherein
- Ar is a substituted or unsubstituted aromatic radical with a valence of at least two,
- R is independently a substituted or unsubstituted divalent radical derived from alkyl or arylalkyl,
- R3 is a hydroxy substituted divalent radical derived from an alkyl radical,
- R4 is independently a vinyl carboxy radical or a epoxy radical, provided that the ratio of n to the number of vinyl carboxy R4 groups is, on average for the composition, from about 0.4 to about 2.0, and
- n is from 1 to 5.
