Abstract
Abrasive aggregates and fixed abrasive articles comprising formaldehyde-free polymer binder and a plurality of abrasive grains are provided that are particularly suitable for machining operations, in which abrasion is carried out to remove material and improve surface quality. Certain embodiments combine an abrasive grain, which can be in the form of microparticles, and a formaldehyde-free polymer binder, which can be in the form of a polymer resin and cross-linking agent. Optionally, the abrasive aggregate can contain a secondary cross-linking agent, or a functional filler, such as a grinding aid.
