COATED ABRASIVE BINDER CONTAINING TERNARY PHOTOINITIATOR SYSTEM

Coated abrasive binders are made from a photocurable addition-polymerizable composition containing a free-radically polymerizable monomer and a photoinitiator system containing i) an arylidonium salt, ii) a sensitizing compound, and iii) an electron donor having an oxidation potential that is greate...

More Information
Summary:Coated abrasive binders are made from a photocurable addition-polymerizable composition containing a free-radically polymerizable monomer and a photoinitiator system containing i) an arylidonium salt, ii) a sensitizing compound, and iii) an electron donor having an oxidation potential that is greater than zero and less than or equal to that of p-dimethyoxybenzene (1.32 volts vs. S.C.E.). The binders cure rapidly and deeply under ultraviolet or visible light, even when filled with large amounts of mineral grain or with coarse grades of minerals.
