摘要： PROBLEM TO BE SOLVED: To obtain an aqueous cutting fluid excellent in disperse stability and viscosity stability of abrasive grains and especially effective for wire saws and an aqueous cutting fluid usable therefor and provide a method for cutting hard and brittle materials excellent in processing accuracy, washing property, etc., of material to be cut. SOLUTION: This cutting fluid comprises a cationic water-soluble resin having 20-200 mg KOH/g amine value and at least one or more kinds of viscosity adjusters selected from inorganic and organic bentonite and aqueous silica sol and has nonvolatile substance content of the viscosity adjuster in an amount of 0.1-30 wt.% based on nonvolatile substance content of the cationic water-soluble resin. This method for cutting crustaceous materials comprises cutting hard and brittle materials with a cutter by using an aqueous cutting fluid obtained by adding abrasive grains to the above aqueous cutting fluid so that the content of the abrasive grains becomes 100-1,000 wt.% based on the nonvolatile substance content of the aqueous cutting fluid.

摘要： PROBLEM TO BE SOLVED: To obtain a water-dispersed water-base coating compsn. which is excellent in applicability and storage stability and can form a coating film excellent in appearance (gloss, smoothness, etc.), resistances to boiling water and gasoline, impact strength, etc., by compounding a specific water-base dispersion of an acrylic block copolymer with an amino resin. SOLUTION: Ths compsn. contains 100 pts.wt. water-base dispersion and 5-60 pts.wt. amino resin (e.g. Cymel). The dispersion is obtd. by copolymerizing 90-40wt.% α,β-ethylenicaly unsatd. low-acid-value monomer mixture having an acid value of 5mgKOH/g or lower, a hydroxyl value of 30-150mgKOH/g, and a glass transition temperature of -20 deg.C to 50 deg.C and 10-60wt.% α,β- ethylenically unsatd. high-acid-value monomer mixture having an acid value of 30-50mgHOK/g, a hydroxyl value of 30-150mgKOH/g, and a glass transition temperature of -20 deg.C to 50 deg.C, neutralizing at least 50% of the acid value of the resultant block copolymer having an acid value of 10-40mgKOH/g, a hydroxyl value of 30-150mgKOH/g, and a glass transition temperature of -20 deg.C to 50 deg.C with a basic substance, and dispersing the block copolymer in water.
