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.

Question 1

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

Question 2

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

Question 3

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

Question 4

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

Question 5

What options are available when selecting a rheology modifier that doesn't require neutralization?

A Dispersants

B Rheology modifiers

C Titanium dioxide

D Latex

That's correct! Rheology modifiers that are highly psedoplastic, such as Rheovis® PU 1191, hold up to the high energy of spray applications and recover once applied.

A Not possible

B Pseudoplastic thickener

C Low shear builder

D Newtonian rheology modifier

You've got it! Newtonian type rheology modifiers like Rheovis® PU 1341 EC are ideal for providing good flow and leveling.

Nope, that's not it. Newtonian type rheology modifiers like Rheovis® PU 1341 EC are ideal for providing good flow and leveling.
Next Question

A Adding attapulgite

B Maintaining a high KU

C Keeping surfactants to a minimum

D Reducing the shelf life on the paint label

That's correct! Gelling attapulgites act as suspension aids to keep particles in solution and keep mixtures from separating. Attagel® 40 forms colloidal gels to provide thixotropic thickening and suspension.
Next Question
Close, but not quite. Gelling attapulgites act as suspension aids to keep particles in solution and keep mixtures from separating. Attagel® 40 forms colloidal gels to provide thixotropic thickening and suspension.
Next Question

A Increase the solids

B Remove water

C Apply heat

D Use rheology modifiers

Yes! One of the primary roles of rheology modifiers 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® PE 1331 EC to acheive the profile that is right for you.

A HEUR

B HMPE

C ASE

D All of the above

You got it! The correct answer of "all of the above" may be surprising. Traditionally, most HASE and ASE thickeners require neutralization. However, BASF offers Rheovis® AS-1187, which is a unqiue inverse emulsion which will function across a wide pH range, from 6-10. Rheovis® AS-1187 provides a pseduoplastic rheology profile.
