CRAYVALLAC® ULTRA is a pure polyamide especially recommended in 2K epoxy primers for its robustness. CRAYVALLAC® ULTRA is a micronised amide wax rheology modifier offering very good recoatability for ambient curing solvent-based epoxy coatings. CRAYVALLAC® ULTRA has been designed to overcome those difficulties which exist with older type organo-wax rheology modifiers e.g. seeding, false-body and migration of readily dissolved species to the surface. Consequently, when used in strong solvent systems, coatings formulated using CRAYVALLAC® ULTRA offer an enhanced performance and very good recoatability.
