ABRASIVE ARTICLE WITH HYDROPHILIC/LIPOPHILIC COATING

摘要

The present invention relates to a flexible abrasive article that has enhanced dimensional and conformational stability, the abrasive article comprising a backing material having first and second opposed major surfaces and an abrasive layer comprising abrasive particles and binder secured to the said first major surface, the article also bearing a hydrophilic/lipophilic urethane material to enhance dimensional and conformational stability of the abrasive article, wherein the said hydrophilic/lipophilic urethane material is selected from the group consisting of: a) products of reaction of a polyisocyanate, a polyethylene oxide and a long chain aliphatic alcohol, in admixture with a polymer derived from acrylic acid or an .alpha.- or .beta.-substituted acrylic acid, and b) polymers with an ethylene-containing backbone bearing urethane-linked nitrogen- bonded hydrocarbon groups and oxygen-linked water solubilizing groups.
