Benefits of HEUR Rheology Modifiers for Waterborne Coatings

Borchi® Gel 0435 develops outstanding brush and roll application properties and high shear thixotropy.  This rheology additive produces viscosity stability mainly in the high shear range.



Ideal applications include general industrial, leather, and decorative coatings. Borchi® Gel 0435 works well in water-based adhesives and sealants.
