Crayvallac® Rheology modifiers for coatings, adhesives & sealants
The range of CRAYVALLAC® additives have been developed to help formulators improve the performance of solvent-free, solvent-based and water-borne coatings.
Coating Resins by Arkema proposes a wide variety of functional additives for decorative and industrial coatings, sealants, adhesives and inks. Crayvallac® additives include rheology modifiers, surface modifiers (designed to improve properties like matting, anti-abrasion, slip and rub, sanding and texturing), and flow and leveling agents.
The range is available and well-known globally for its performance properties.

Organic powders Incorporation and benefits
In formulations, organic powders confer a strong shear-thinning behavior leading to ease of mixing, pumping and applying, and an excellent viscosity recovery enabling high sag resistance.
Supplied under micronized form, they are easy to incorporate in formulations and will develop their rheology upon high shear stirring – which is commonly named activation. This video is an example on how to incorporate an organic powder.
Pastes benefits
In formulations, polyamide pastes confer a strong shear-thinning behavior leading to ease of mixing, pumping and applying, and an excellent viscosity recovery enabling high sag resistance.
Supplied under paste form, they are very easy to incorporate in formulations and will develop their rheology upon medium shear stirring. This video illustrates how to incorporate a polyamide paste.
