[0039] Method of making anti-fill composition

[0040] Calcium 12-hydroxystearate ("CS-6", manufactured by NITTO CHEMICAL INDUSTRY CO.LTD., solid content: 30%) and methylcellulose ("Metolose SM-15", manufactured by SHIN-ETSU CHEMICAL CO.LTD. manufactured, solid content: 8%) was mixed with water and dispersed with a stirrer at 500 rpm for 30 minutes to obtain an anti-caking composition.

[0041] Measurement of wetting tension

[0042] The wetting tension of the coating formed from the obtained anti-filling composition was measured according to JIS K 6768 "Test Method for Wetting Tension of Plastic, Film and Sheet (Method for Determination of Wetting Tension of Plastics, Films, and Sheets)", JIS K The disclosure of 6768 is incorporated herein by reference. Accordingly, the film thickness of the anti-fill coating was measured to be 35 micrometers (μm). In addition, the coating amount and suitable drying conditions of the anti-caking composition are determined according to ...

Abstract

To improve the endurance of the antiloading effect of an antiloading composition for an abrasive article. The antiloading composition for an abrasive article, comprising a metal salt of a fatty acid and a binding resin, wherein a coating formed therefrom has wetting tension of more than 44 mN / m.

Description

technical field [0001] The present invention relates to antiloading compositions for abrasive articles, and abrasive articles having antiloading coatings. Background technique [0002] Abrasive articles are conventionally used for abrading (sanding) various substrates or workpieces and the like. One of the problems with the sanding process is the "packing" problem. That is, dust that has been ground from the workpiece collects between the abrasive grains, thereby causing deterioration in the cutting ability and performance of the abrasive article even if the abrasive grains are not worn. [0003] Accordingly, in the abrasive article industry, research has been conducted into the use of antiloading compositions in abrasive articles. For example, metal salts of fatty acids are known to be useful as anti-filling agents in anti-filling compositions. Contents of the invention [0004] Anti-loading agents, ie metal salts of fatty acids described in the art, have been shown to...
