COATED ABRASIVE ARTICLE AND METHOD OF MAKING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18029501 titled 'COATED ABRASIVE ARTICLE AND METHOD OF MAKING THE SAME

Simplified Explanation

- The patent application describes a method of making a coated abrasive article. - The method involves applying a curable composition on a backing surface, adhering abrasive particles to the composition, and partially curing the composition. - The curable composition includes a phenolic resin component, a free-radically polymerizable component, and an organic polymeric rheology modifier. - The organic polymeric rheology modifier is an alkali-swellable/soluble polymer and makes up a small percentage of the overall composition. - The method can also be modified to adhere the abrasive particles before partially curing the composition. - The patent application also mentions that the resulting abrasive articles made using this method are disclosed.

Original Abstract Submitted

A method of making a coated abrasive article comprises sequential steps: disposing a curable composition on a major surface of a backing b) adhering abrasive particles to the curable composition; c) at least partially curing the free-radically polymerizable component; and d) at least partially curing the phenolic resin component to provide an at least partially cured composition. The curable composition comprises a phenolic resin component, a free-radically polymerizable component, and an organic polymeric rheology modifier, wherein the organic polymeric rheology modifier comprises an alkali-swellable/soluble polymer, and wherein, on a solid basis, the organic polymeric rheology modifier comprises from 0.001 to 5 weight percent of the phenolic resin component, the free-radically polymerizable component, and the organic polymeric rheology modifier combined. A variant wherein step b) effectively occurs after step c) is also disclosed. Abrasive articles made according to the methods are also disclosed.
