Bitumen roofing Imerys talc - an excellent process aid for bitumen roofing products
Coarse-grind Imerys talc grades are used to back-surface hot asphalt in the production of bitumen membranes, bitumen-based felt and modified bitumen-sheet roofing products.
- Prevent sticking or caking in storage
- Facilitate surface mineralization of the bitumen membrane
Our finer talc grades are also used as fillers in modified bitumen roofing where they:
- Reduce volatile loss
- Provide better UV and weathering properties
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
