    摘要: Provided are flow-and-leveling agents for powder coatings which provide the coated surfaces with a flow-and-leveling property by blending into powder coatings taking a serious view of finishing and which improves coating defects such as ruptures and craters to contribute to a rise in the appearance in powder coating. The above flow-and-leveling agents are (meth)acrylic acid ester base copolymers containing a trimethylsilyl group in a proportion of 2 to 65 % by weight and having a number average molecular weight of 1000 to 60000.

    摘要: A curable coating composition is described comprising a carbamate functional material, a crosslinking agent and a hydroxyl functional polysiloxane component. Coatings prepared with this coating composition can be cured and coated with additional coating(s), providing good intercoat adhesion to the subsequent coating.

    摘要: Curable coating compositions comprising either a liquid or particulate curable film-forming resinous material, a flow control agent which is a copolymer and optionally a carrier for the liquid resinous material. The copolymer is from at least one non-amino, non-hydroxyl and non-acid functional alkyl acrylate or methacrylate containing from 1 to 20 carbon atoms in the alkyl group, and functional monomer of either (i) amino functional acrylates and methacrylates in an effective amount to give the copolymer an amine value in the range from 2 to 25, or (ii) acid functional acrylate and methacrylate in an effective amount to give the copolymer an acid value in the range of from 10 to 30. Additionally, with either functional monomer (i) or (ii) another functional comonomer (iii) can be present in the copolymer which is hydroxyalkyl acrylate and/or hydroxyalkyl methacrylate and/or caprolactone polyol monomer. Comonomer (iii) can be present in the copolymer in an effective amount to give the copolymer a hydroxyl number which is in the range of about 0 to 100. The copolymer flow modifiers enhance the rheology of the curable film-forming resinous material like thermosetting powder coating compositions to provide for smoother coatings while at the same time not adversely affecting appearance or adhesion with associated coatings, for example, basecoats when the coating composition is a clearcoat.
