It is an object of the present invention to provide a surface conditioner for a coating agent. The surface agent, which is blended into the coating agent in small amounts, can impart a base material-wetting property and a cissing-preventing property to the coating agent when blended in the coating agent, can impart a leveling property to the coating layer which the coating agent is applied to form a coating layer so as to improve the appearance and smoothness of the surface thereof, can improve an adhesion property of over-coating, can impart an excellent leveling property with heat resistance to the coating agent when blended in a baking paint which is cured at a high temperature. It is another object of the present invention to provide a coating agent to which said surface conditioner is blended. The surface conditioner for the coating agent comprises: a copolymer composed of 1 to 40 parts by weight of an acrylate monomer (A) having a siloxy group, 2 to 80 parts by weight of an N-vinyllactam monomer (B), and 10 to 97 parts by weight of an alkyl (meth)acrylate monomer (C) of which an alkyl group has 1 to 12 carbon atoms; and weight average molecular weight of the copolymer is 1000 to 120000.

摘要:
Compositions comprising at least one acrylic, vinyl acetate or epoxide polymer or copolymer as a film-forming ingredient and an ester of benzoic acid wherein the alcohol portion of the ester is alkyl and contains eight carbon atoms exhibit unexpected improvements in film-forming and applied film properties. In preferred compositions this alcohol portion is 2-ethylhexyl. Additionally, the preferred benzoic acid ester frequently interacts synergistically with benzoic acid esters derived from oligomeric ethylene glycols.
