Rheology

Rheology Imerys minerals can have a significant positive effect on the rheological properties of adhesives and sealants

Rheology is a key parameter in adhesives and sealants affecting storage stability, extrusion rate, slump and sag resistance, service life and cure rate. Imerys minerals have a value added positive effect on the rheological properties of adhesives and sealants.

Imerys minerals improve:

  • Rheological properties for storage stability, sag and slump resistance and extrusion
  • Service life: Cure rate, substrate compatibility and tooling time
  • Lightweighting: Reduce overall formulation density
