CRAYVALLAC® PA4BA20

CRAYVALLAC® PA4 BA 20 is a HAPs-free rheology modifier pre-activated amide wax supplied in a mixture of butyl acetate and alcohol. It is a rheology modifier in paste form with enhanced transparency, excellent anti-sagging and anti-settling properties. CRAYVALLAC® PA4 BA 20 is supplied in the form of crystalline fibres. In a coating system, these fibres form an interacting network. This network gives rise to the shear thinning rheology of the final coating. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.

CRAYVALLAC® MT

CRAYVALLAC® MT is a micronised amide modified hydrogenated castor oil rheology modifier for solvent-based and solvent-free systems. CRAYVALLAC® MT is suited to systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to the most basic hydrogenated castor oil based rheology modifiers, CRAYVALLAC® MT is more tolerant to stronger solvents. CRAYVALLAC® MT particles are converted upon activation into an interacting network of fibre like particles. This network gives rise to the final coating’s shear thinning rheology. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.

COAPUR XS83

COAPUR™ XS 83 is a solvent-free polyurethane thickener recommended for water-based systems which should combine high in-can viscosities with excellent pigment compatibility, for use on tinting machine, manual coloration, industrial and architectural coatings. COAPUR™ XS 83 provides a unique pseudoplastic rheology profile with a strong shear-tinning behavior. Its use ensures a smooth structure and an optimized ease of application by spray, roller or brush. The highly pseudoplastic rheology profile, combined with a fast recovery of the viscosity following the application makes the COAPUR™ XS 83 suitable for industrial and decorative applications requiring high film thicknesses and excellent sag resistance. COAPUR™ XS 83 contributes to improve colour strength and reduce rub-out issues when using pigment pastes, even in presence of problematic binders. The use of COAPUR™ XS 83 also limits viscosity drop after pigment paste addition, pigment flooding and floating during storage.
