Japanese Patent JP2696039
Kind Code:
B2
Abstract:
A hardenable composition suitable for flooring and for coating concrete surfaces comprises (a) an acrylic binder comprising a (meth)acrylic ester of the formula < IMAGE > wherein R is hydrogen or methyl and R1 is C2-6aklylene, n is 0-3 and R2 is a radical of an aromatic or alicyclic dicarboxylic acid ester or a dicyclopentenyl radical, the value of 0 for n only being possible when R2 is a dicyclopentenyl radical, (b) a component which is one or both (preferably both) of carbon black and a polyfunctional aliphatic or aromatic polyester- or polyether- urethane oligomer. The composition also preferably comprises aggregate such as sand. The compositions have excellent impact resistance and flexural strength. The carbon black has a BET surface area of 20 to 460 M<2>/g and is present in an amount of 0.01 to 7% by weight based on the acrylic monomer (a). The oligomer( b) has a molecular weight of 500 to 2000 and a viscosity of 2000 to 100,000 mPas at 25 DEG C and contains at least two ethylenically unsaturated double bonds. The binder may additionally comprise other (moth) acrylic esters, e.g. hydroxyalkyl methacrylates. In the examples component (a) is an ester of tetrahydrophthalic acid monomethyl ester and hydroxypropyl methacrylate.
