  • Patent number: 8143342
    Abstract: Disclosed is a coating agent including a synthetic resin emulsion (A) wherein an acrylic resin of which the main monomer component is an alkyl ester of (meth)acrylic acid, and a silicone resin of which the main monomer component is a cyclic siloxane compound are mixed in emulsion particles to set the ratio by weight of the former to the latter into the range of 99/1 to 30/70, and a particulate matter (B) having an average particle diameter of 0.5 to 500 ?m and an oil absorption of 60 mL/100 g or less, wherein the particulate matter (B) has a pigment volume concentration of 10 to 90%. When this coating agent is stored or after a paint film is made therefrom, a fall in the water repellent effect thereof is restrained, so that an excellent water repellent performance can stably be exhibited.

  • Patent number: 6433076
    Abstract: There is provided a low-staining agent which can outstandingly improve an anti-staining property and a property of preventing penetration of a staining substance when it is added to an aqueous paint, which does not affect a weather resistance and a water resistance of the paint, and which has an excellent compatibility with the aqueous paint. The present invention also relates to a low-staining aqueous paint composition to which said low-staining agent is added. The present invention relates to an aqueous paint low-staining agent which is a modified condensation product of alkoxysilane having at least one polyoxyalkylene group and an alkoxyl group, wherein a repetition unit of said polyoxyalkylene group has 1 to 4 carbon atoms, and said alkoxyl group has 1 to 4 carbon atoms. In particular, it is preferable that the polyoxyalkylene group is a polyoxyethylene group and the alkoxyl group is an ethoxy group.

  • Patent number: 6271293
    Abstract: The present invention relates to a coating composition, which forms an anti-contamination coat having hydrophilicity on the surface, soil-release effect and excellent stain resistance to oil, and which is also suitable for outside wall coating of buildings, having excellent interlaminar adhesion when multiple coating is performed. A conventional anti-contamination coating was insufficient in stainproofing performance immediately after formation of the coat, and there was no coating which is superior in stain resistance to oil and interlaminar adhesion.
