Disclosed is a heat radiation shield coating composition containing a black pigment which exhibits a reflectance of not below 8.0% relative to a solar radiation in the 780-2,100 nm wavelength region. The black pigment preferably exhibits a reflectance of not higher than 15% relative to a radiation at any wavelength in the 400-700 nm visible region.

Heat radiation shield coating composition

The present invention relates to a paint film embodying a new parameter representing the resistance to raindrop fouling and having very satisfactory fouling resistance, particularly resistance to raindrop fouling, even ultra-low foulability, as well as high water resistance, acid resistance, alkali resistance, and crack resistance; a coating composition capable of providing said paint film; a method for forming a satisfactory paint film using said coating composition; and an article coated with said paint film. A coating composition comprising (I) a tetramethoxysilane partial hydrolyzed condensate and at least one member selected from (A) a film-forming resin and (B) an inorganic binder containing alkoxysilyl as a reactive curing group and having a water dynamic reverse tension (Tr) of not less than 55 dyn/cm; and an antifouling paint film containing the coating composition is provided.

Raindrop fouling-resistant paint film, coating composition, film-forming

A thermosetting resin or coating composition contains (a) a film-forming polyol resin, (b) a curing agent reactive with the polyol resin, (c) a hydrolyzate/polycondensate of tri- or tetraalkoxysilane, and (d) a catalyst for promoting the reaction between the polyol resin (a) and the curing agent (b).

Thermosetting resin composition

A curing type resin composition used as a molding material, a paint binder, etc. comprises a curing agent and a copolymer composed of a silicone compound and an .alpha., .beta.-unsaturated vinyl monomer. The silicone compound is selected from the group consisting of silicone compounds having the following general structural formulas (1) and (2) respectively, and the curing agent has at least two functional groups, individual molecules of which react with a functional group in the groups Y of the silicone compound. ##STR1## wherein: X is selected from the group consisting of a 3-acryloxypropyl group and a 3-methacryloxypropyl group;
