The thickening agents in the Crayvallac® range from ARKEMA are specialty derivatives from castor oil, polyamide, polyurea, polyurethane and oxidised polyethylene. These are mostly powders whereas some of the products are also available as preactivated solventbased pastes. Some are solved in specialty solvents to be suitable as a pourable post-add.
These additives provide highly shear thinning properties to solventborne, solventfree and waterbased coatings, paints and adhesives and help to improve in-can stability, antisagging, pumpability and levelling.
Applications for Crayvallac® rheology additives are coatings for marine, automotive, wood, industrial and protective purpose as well as high performance adhesives and sealants.
