Abstract
This invention provides a composition for anchoring materials in or to concrete or masonry. The composition comprises an alkylacrylate ester monomer, an alkylacrylate ester/methacrylic acid copolymer, a free-radical catalyst and a filler.
Claims21
A low-temperature curable composition for anchoring materials in or to concrete or masonry, which composition comprises:
- a. alkylacrylate ester monomer;
- b. a copolymer of alkylacrylate ester and methacrylic acid monomers;
- c. from about 10% to about 90% by weight of an inert, inorganic, solid, particulate filler;
- d. from about 0.5% to about 10% by weight of a free-radical catalyst;
- e. from about 0.1% to about 5% by weight of a chain transfer agent;
- and
- f. from about 0.01 to about 10% by weight of an activator,
- wherein said composition is curable at 20.degree. F. (-7.degree. C.).

A low-temperature curable composition for anchoring materials in or to concrete or masonry that is made by mixing a first composition which comprises:
- a. a solution of methacrylate ester monomer and methacrylate ester/methacrylic acid copolymer;
- b. from about 10% to about 90% of an inert, inorganic, solid, particulate filler;
- c. from about 0.1% to about 5% of a chain transfer agent;
- and
- d. from about 0.01 to about 10% of an activator, and
- a second composition which comprises from about 0.5% to about 10% of a free-radical catalyst, wherein said low-temperature curable composition is curable at 20.degree. F. (-7.degree. C.) and wherein all percentages are by weight based on the total weight of the curable composition.
