Rheology Modifiers, Thixotropes and Thickening Agents for Adhesives and Sealants

Manufacturers of adhesives, sealants and other engineered materials around the world have relied on our PPG HI-SIL® silica thickening agents, rheology modifiers and thixotropes  to help address the complex formulation, manufacturing, application and performance challenges they face.

Available in four grades, Hi-Sil thickening agents cover a range of particle sizes and surface areas. Together, they offer manufacturers a selection of products to achieve desired rheology properties and anti-sag/suspension performance with minimal impact on other system properties.

Hi-Sil thickening agents provide enhanced performance and efficiency in non-polar and medium-polar solvent systems.
