Abstract

The invention pertains to a process for manufacturing a filled polymeric material comprising a polymeric matrix and filler modified with functional particles in a high energy dry-blending process through collisions of sufficient energy to bound, adhere, or otherwise associate the pigment particles to the filler.

Claims (8)

1. A filled polymeric material comprising a polymeric matrix and a modified filler particle comprising a filler particle modified with discrete functional particles that are bound or adhered to the filler.

2. The filled polymeric material of claim 1 , wherein the polymeric matrix comprises a liquid prepolymer.

3. The filled polymeric material of claim 1 , wherein the polymeric matrix comprises a polymer that is prepared from a liquid prepolymer.

4. The filled polymeric material of claim 1 , wherein the discrete functional particles are pigment particles.

5. The filled polymeric material of claim 4 , wherein the material is a solid surface material.

6. The filled polymeric material of claim 5 , wherein the solid surface material is a countertop.

7. The filled polymeric material of claim 5 , wherein the solid surface material is a sink.

8. The filled polymeric material of claim 5 , wherein the solid surface material is building cladding.
