HEUR Rheology Modifier for the High Shear Range / Paints and Coatings

Borchi® Gel 0434 is a HEUR rheology modifier (Hydrophobically modified Ethoxylated Urethane copolymer rheology modifier) with excellent thickening efficiency. This solution works well as a high shear range thickener for improved rheological profiles in coatings. Borchi® Gel 0434 is a non-ionic, polyurethane-based additive for water-based coatings systems. It is glycol ether-, tin- and VOC-free.

Benefits of HEUR Rheology Modifiers for the High Shear Range

Borchi® Gel 0434 promotes good gloss and flow and leveling properties in paints, inks, and adhesives. This HEUR thickener yields spatter resistant coatings with outstanding brush/roller application properties and good physical properties in paint formulations. Borchi® Gel 0434 improves water sensitivity, prevents sagging, and quickly develops high shear thixotropy. This solution provides excellent hiding power for coatings.
