Abstract
A hardenable monomer composition useful for flooring composition, grouts, mortars and the like comprises a mixture of crosslinkable acrylic monomer, carbon black and/or polyester- or polyether-methane oligomer having at least two polymerizable double bonds and a paraffin oil. The monomer is preferably of the formula I ##STR1## and there is preferably present other monomers, particularly hydroxypropyl methacrylate.
Claims22
A method of forming a floor on a cementitious substrate comprising applying to said cementitious substrate a hardenable monomer composition comprising
- (a) at least one cross-linkable acrylic monomer with a flash point above 50.degree. C.;
- (b) at least one material selected from the group consisting of
- (i) 0.01 to 7% by weight of carbon black said weight based on the weight of the monomer, and
- (ii) at least one polyfunctional polyester- or polyether-urethane/acrylate oligomer;
- and
- (c) from 0.01-1% by weight, based on the weight of the total composition, of at least one paraffin oil, said paraffin oil having a density which is lower than the density of the remainder of the composition.
A method of forming a coating on a cementitious substrate comprising coating said cementitious substrate with a hardenable monomer composition comprising
- (a) at least one cross-linkable acrylic monomer with a flash point above 50.degree. C.;
- (b) at least one material selected from the group consisting of
- (i) 0.01 to 7% by weight of carbon black said weight based on the weight of the monomer, and
- (ii) at least one polyfunctional polyester- or polyether-urethane/acrylate oligomer;
- and
- (c) from 0.01-1% by weight, based on the weight of the total composition, of at least one paraffin oil, said paraffin oil having a density which is lower than the density of the remainder of the composition.
A method of repairing cracks and fissures in a cementitious substrate comprising applying to said cracks and fissures a hardenable monomer composition comprising
- (a) at least one cross-linkable acrylic monomer with a flash point above 50.degree. C.;
- (b) at least one material selected from the group consisting of
- (i) 0.01 to 7% by weight of carbon black said weight based on the weight of the monomer, and
- (ii) at least one polyfunctional polyester- or polyether-urethane/acrylate oligomer;
- and
- (c) from 0.01-1% by weight, based on the weight of the total composition, of at least one paraffin oil, said paraffin oil having a density which is lower than the density of the remainder of the composition.
A method of adhering together at least two cementitious substrates comprising applying a hardenable monomer composition to a surface of at least one cementitious substrate to form an adhesive coated surface, bringing said adhesive coated surface into contact with a surface of a second cementitious substrate and allowing the hardenable monomer composition to harden, said hardenable monomer composition comprising
- (a) at least one cross-linkable acrylic monomer with a flash point above 50.degree. C.;
- (b) at least one material selected from the group consisting of
- (i) 0.01 to 7% by weight of carbon black said weight based on the weight of the monomer, and
- (ii) at least one polyfunctional polyester- or polyether-urethane/acrylate oligomer;
- and
- (c) from 0.01-1% by weight, based on the weight of the total composition, of at least one paraffin oil, said paraffin oil having a density which is lower than the density of the remainder of the composition.
