Abstract
The production of an engineered surface on a coated abrasive is made more versatile by the use of a production tool obtained using a master tool created by a rapid prototyping technique.
Claims8
A process for producing a coated abrasive with an engineered surface which comprises;
- a) using a rapid prototyping technique to produce a master tool;
- b) using the master tool as a mold from which to make a plurality of production tool sections;
- c) assembling said sections to produce a cylindrical production tool having a patterned surface;
- d) depositing a layer of a curable binder resin having abrasive particles dispersed therein on a substrate;
- e) using the production tool to impose a pattern on the layer;
- and
- f) curing the curable binder resin to produce a coated abrasive having an engineered surface.
