Crayvallac PA3-B20 Amide wax Cray Valley Rheology Modifier/ Thickener >> Organowax >> Polyamide-based organowax Coatings >> Solventborne Architectural / Decorative General Industrial /Maintenance Wood & Furniture Coatings butyl acetate/alcohol Crayvallac PA3-B20 Crayvallac PA3-B20 is a HAPs-free alternative to Crayvallac PA3X20. This rheology modifier is composed of a pre-activated amide wax dispersed in a mixture of butyl acetate and alcohol. This product enables the formulator to control both sedimentation and sag. In order to obtain the maximum efficiency from Crayvallac PA3-B20, it is necessary to disperse this product without destroying the crystalline fibres. It is therefore preferable to incorporate Crayvallac PA3-B20 under low to medium shear conditions, over as short a time period as possible. HAPs free pre-activated amide wax dispersed in mixture of butyl acetate and alcohols. Suitable for post-addition to solvent-based industrial coatings. Used for wood finishes/decorative coatings. Provides very good control of sedimentation and sag. Easy to incorporate. Imparts shear-thinning rheology with thixotropic viscosity recovery. Provides very good anti-settle properties and good recoatability.
