A process for producing a powder coating material containing a powder (X) composed of a composition (±) comprising a fluororesin (A) having carboxy groups, or alkoxysilyl groups and urethane bonds, and a curing agent (D), said process comprising (a) a step of melt-kneading a mixture comprising a hydroxy group-containing fluororesin (B), an acid anhydride (C1) or a compound (C2) having an alkoxysilyl group and an isocyanate group, and the curing agent (D), to obtain a kneaded product composed of the composition (±), and (b) a step of pulverizing the kneaded product to obtain the powder (X).
Abstract:
An erodible antifouling coating composition for application, for example,to ship's hulls to potentially prevent the adhesion and build up of fouling agents on the hull is described. The coating composition comprises an erodible binder system excluding a triorgano tin based binder; optionally, one or more antifouling agents; and at least one silicone oil.A process for producing the composition, a substrate coated with the composition, and a process of coating a substrate with the composition are also described.
Abstract:
The present invention aims to develop an aqueous heat-shielding coating material to which low staining properties are imparted to suppress a reduction in heat-shielding properties due to the reduction in solar reflectance caused by adhesion of contaminants in the air during outdoor exposure, thereby maintaining the heat-shielding properties for a long period of time. The above problem is solved by providing a resin composition for an aqueous coating material including: (A1) a water-soluble and/or water-dispersible resin; (A2) a heat-shielding pigment; (B1) an organosilicate and/or a modified product of the organosilicate; and (B2) a curing catalyst that promotes a hydrolysis/condensation reaction of an alkoxysilyl group.
Abstract:
To provide a fluorinated ether compound, a fluorinated ether composition and a coating liquid, whereby it is possible to form a surface-treated layer which has high initial water/oil repellency and which is excellent in abrasion resistance and fingerprint stain removability, and a substrate having a surface-treated layer and a method for its production. A fluorinated ether compound which has a poly(oxyperfluoroalkylene) chain ((αβ) n ) made of at least two units (αβ) linked to one another, and which has a hydrolysable silyl group on at least one terminal of the chain ((αβ) n ) via a linking group, wherein each unit (αβ) is a poly(oxyperfluoroalkylene) group comprising one to three groups (α) made of at least one type of a C 1-2 oxyperfluoroalkylene group and one to three groups (β) made of at least one type of a C 3-6 oxyperfluoroalkylene group.
Abstract:
An object of the present invention is to provide a curable composition that provides high hardness and can be used in adhesives and coating agents. This object can be achieved by a curable composition containing: 100 parts by weight of a reactive silyl group-containing organic polymer (A) that has a number average molecular weight of 2, 000 to 6, 000 and contains 1.3 to 5 reactive silyl groups per molecule; and 0 to 40 parts by weight of a plasticizer (C). This curable composition is suitable for flooring adhesives and tile adhesives, which require high hardness.
Abstract:
Provided is a method of forming an antifouling coating film including the steps of [1] preparing a colored antifouling paint containing a prescribed Si-containing hydrolyzable resin and a color pigment such that a coating film having a target dry film thickness T completely hides a surface of an object to be coated, the colored antifouling paint has a color difference ”E1 between the coating film having the thickness T and a coating film having a dry film thickness of 0.8 T, at least 2.0, and preferably the colored antifouling paint has a color difference ”E2 between the coating film having the thickness T and a coating film having a dry film thickness of 1.2 T, less than 1, and [2] coating a surface of the object with the colored antifouling paint until the surface of the object is completely hidden by the coating film formed from the colored antifouling paint.
