ABSTRACT:
The preparation of abrasives, especially abrasive papers and abrasive fabrics, is improved by using an epoxy resin in conjunction with a cationic photoinitiator as binder for the abrasive particles. The binder is cured by irradiation with shortwave light and subsequent heating. The process is distinguished by low curing temperatures and brief curing times.
