Abstract
This invention provides a composition for anchoring materials in or to masonry. The composition comprises a methacrylate ester monomer, a methacrylate ester polymer, a free-radical catalyst and a filler.
Claims28
A system for anchoring bolts in structural bodies comprising:
- (a) a structural body selected from the group consisting of concrete bodies, masonry bodies and rock;
- (b) an anchor bolt;
- and
- (c) a cured polymer composition adhesively contacting said structural body and said bolt, said cured polymer composition providing a pull-out force of at least about 2200 lbs. in medium weight concrete block and having been cured from a curable composition comprising:
- i. from about 20% to about 90% by weight of a solution of methacrylate ester polymer in methacrylate ester monomer;
- ii. inorganic filler;
- iii. free-radical catalyst;
- and
- iv. trimethyl hydroquinone as a free-radical inhibitor.

- (b) delivering to said structural body a curable adhesive composition comprising:
- i. from about 20% to about 90% by weight of a solution of methacrylate ester polymer in methacrylate ester monomer;
- ii. inorganic filler;
- iii. free-radical catalyst;
- and
- iv. trimethyl hydroquinone as a free-radical inhibitor;
- (c) contacting said curable composition with an anchor bolt;
- and
- (d) curing said adhesive composition to produce a cured composition which provides a pull-out force of at least about 2200 lbs. in medium weight concrete block.
