How to enhance paints properties with our latest innovations on polyurethane thickeners

Arkema Rheology & Specialty Additives, a leader in polyurethane thickeners, continues its commitment to innovation in the paints and coatings markets.
This case study will showcase our two latest developments in this field.

• First, in order to improve film build and leveling without impacting the in-can appearance and low shear viscosity, the Coapur™ XS 12, a pure Newtonian HEUR thickener, uniquely enhances high shear viscosities. It is a new tool showing also very good compatibility and rheology response with all types of binders.

• Second, Coapur™ XS 83 will provide a very pseudoplastic behaviour with a strong shear-thinning profile. As a consequence it is a tremendous polyurethane thickener to improve sag resistance with a superior color acceptance. This new thickeners has proven its efficiency and suitability in both decorative and industrial coatings.

These sustainable additives are powerfully enriching the toolbox of paints and coatings formulators.

Key takeaways:

Coapur™ XS 83 

• Highly pseudoplastic PU thickener
• Suitable for decorative and industrial coatings
• High efficiency (do more with less)
• High sag resistance with good leveling

Coapur™ XS 12 

• Unique Newtonian PU thickener
• Excellent leveling
• Impacting only high shear viscosity
• Wide compatibility with most reactive binders
