Get more familiar with our rheology modifier portfolio

Rheology modifiers from BASF effectively reduce dripping and spattering of paints during roller or brush application. Sag resistance is improved by a rapid but controlled viscosity increase after application. They also reliably prevent sedimentation of pigments during transport and storage of the paints.

Q&A

Q: What type of product will help with the atomization of liquid paint droplets for superior spray application performance?

A: Rheology modifiers that are highly pseudoplastic, such as Rheovis PU 1192 and Rheovis PU 1193, hold up to the high energy of spray applications and recover once applied.

Q: How does one minimize brush and roller patterns in a coating using rheology modifiers?

A: Newtonian type rheology modifiers like Rheovis PU 1341 EC are ideal for providing good flow and leveling.

Q: The best way to prevent sedimentation and syneresis development is by...

A: Adding attapulgites - gelling attapulgites act as suspension aid to keep particles in solution and keep mixtures from separating. Attagel 40 forms colloidal gels to provide thixotropic thickening and suspension.

Q: What is the best method for building the viscosity of a coating?

A: Use rheology modifiers - one of the primary roles of rheology modifers is to increase the viscosity, but given the number of choices on the market, it can be hard to select the best one for your formulation. BASF has a full portfolio of rheology modifiers that are designed to thicken in certain regions of the rheology profile. For instance, thickeners in our 1200 series, such as Rheovis PU 1235 EC and Rheovis PU 1251 EC, provide mid-shear or KU viscosity build. Pair them with a high shear builder such as Rheovis PU 1331 to achieve the profile that is right for you.

Q: What options are available when selecting a rheology modifier that doesn't require neutrailzation?
