Rheology of adhesives and sealants

Getting rheology right

Improving rheology can help extend the stability and service life of your adhesives and sealants. We make a range of formulations that have significant positive effects on rheological properties and could be a cost-effective way to improve the quality of your products.

Precipitated calcium carbonate will enhance storage stability, extrusion rate, slump and sag resistance, service life and cure rate, when used in adhesives and sealants. It will also improve substrate compatibility and tooling time.
