ABSTRACT:
A coated abrasive which is advantageous for certain applications has at least two distinct layers of abrasive grits: a coarse outer layer and a finer inner layer. The median particle size of the grits in the outer layer is at least 150% of that of the inner layer grits. The grits may be adhered to the backing with adhesives compounded primarily of acrylates and cured by exposure to UV light. A product made in this way is effective for one step fining of plastic ophthalmic lenses.
