Crayvallac EXTRA Amide wax Cray Valley Rheology Modifier/ Thickener >> Organowax >> Polyamide-based organowax Epoxy Resins Coatings >> Solventborne Coatings >> Solvent-Free/ High-Solids General Industrial /Maintenance Crayvallac EXTRA Crayvallac EXTRA is a high performance micronised amide wax rheology modifier offering very good recoatability for ambient curing epoxy coatings. Crayvallac EXTRA is suited to those systems where insufficient control of sedimentation and sag is obtained when using Crayvallac ULTRA. This is of particular interest for ambient cured solvent-free epoxy primers and high solids systems in general. Crayvallac EXTRA is ideally incorporated and activated using a high-speed. 100% active, high performance micronised amide wax. Used for solvent based and solvent-free ambient curing epoxy coatings. Imparts shear-thinning rheology with thixotropic viscosity recovery. Gives very good anti-settle properties and very good recoatability.
