Definitions
- the present disclosure provides an abrasive article comprising a cork backing layer and an abrasive layer.
- Examples of mixing techniques to mix the binder precursor, abrasive articles and optionally other additives include low shear and high shear mixing, with high shear mixing being preferred. Ultrasonic energy may also be utilized in combination with the mixing step to lower the abrasive slurry viscosity.
- the abrasive particles are gradually added into the binder precursor. It is preferred that the abrasive slurry is a homogeneous mixture of binder precursor, abrasive particles and optional additives. If necessary, water and/or solvent may be added to lower the viscosity.
- the abrasive particles comprise materials selected from aluminium oxide, silicon carbide, boron carbide, iron oxide, steel, boron nitride, ceramic, cork and any combinations and mixtures thereof. These materials are commonly used in coated abrasive articles as they provide significant cut aggression to the surface to be abraded.
- the outer surface of the production tool can be smooth or have a surface topography or pattern.
- the pattern will generally consist of a plurality of cavities or features.
- the resulting abrasive layer will have the inverse of the pattern from the production tool.
- These cavities can be any geometric shape such as rectangle, semicircle, circle, triangle, square.
- a splice adhesive may be added to the surface of the joint 309. This will increase strength of the joint 309.
- IR-369 is a 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1 UV curing agent available under the trade designation IRGACURE® 369 from BASF Corp., Charlotte, N.C., USA.
