Introduction:
Resin for bonded abrasives: powdery or liquid resin. The powdery resin with high bonding strength, good mechanical property and good abrasive property, is used to make grinding wheels with various rigidities. The liquid resin with viscosity, solid content and molecular weight strictly controlled, can be used as the wetting agent for the grinding wheel.
Resin for coated abrasives: water soluble thermosetting liquid resin. It has good bonding property with abrasives, substrate and even metal, good mechanical property after curing, water resistant, grease resistant, chemical resistant, aging resistant, good compatibility with various fillers and latex, and high wettability.
Application:
Resin for bonded abrasives: used in various grinding wheels, including cutting/ultrathin/grinding blades and heavy load/large diameter/ultrahard grinding wheels.
Resin for coated abrasives: used in various coated abrasives, including various abrasive belts, dry grinding/water resistant abrasive cloth/paper, coated abrasive paper, vulcanized fiber discs and non-woven fabric abrasives.
Property:
Powdery resin:
