POLYUREA-BASED MATERIAL, POLISHING AND GRINDING MEDIA INCLUDING THE POLYUREA-BASED MATERIAL, AND METHODS OF FORMING AND USING SAME

摘要

Polyurea-based materials suitable for grinding media and polishing media, media including the polyurea-based material, and methods of forming and using the polyurea-based material and media are disclosed. The polyurea-based material is formed using one or more secondary polyamines, which allows for slower reaction rates and produces material having desired properties.

主权项

1. A polyurea-based material for grinding or polishing a surface of a substrate, the polyurea-based material comprising:
a polyurea, wherein the polyurea is formed from one or more secondary polyamines having a general formula of R[—NH—R]n, wherein n is greater than or equal to 2 and wherein R is not H and R′ is not H; and one or more of polyisocyanates, polyisocyanate derivatives, and polyisocyanate products.
