CRAYVALLAC WF-1039 is a micronised PTFE modified polyethylene wax conforming to FDA 175.300.

CRAYVALLAC® SLT is a high performance micronised amide wax rheology modifier designed for activation-free manufacture of moisture curing methoxysilane based systems. Simple stirring is only necessary to get full efficiency. CRAYVALLAC® SLT is also suitable for the activation-free manufacture of moisture curing methoxysilane based adhesives. CRAYVALLAC® SLT is specially designed for the low temperature manufacture of one-component methoxysilane sealants where processing temperatures typically lie within the range 30 – 80°C. CRAYVALLAC® SLT particles are converted to an interacting network of crystalline fibres. It is this network that gives rise to the shear thinning rheology. This shear thinning characteristic provides for a low viscosity at the shear rates associated with application by extrusion, and a veryhigh viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.

FLOWTONE ST is a micronised amide modified hydrogenated castor oil rheology modifier for solvent-based and solvent-free coatings.

COADIS™ 123 K is a dipersant for water born systems like flat or gloss dispersion paints, renderings and plasters, and also organic pigment pastes (e.g. carbon black dispersion). It is a versatile dispersant, recommended for a broad range of water-borne systems. COADIS™ 123 K provides excellent early water and scrub resistance to formulations with high PVC, excellent gloss level to gloss and semi-gloss dispersion paints and good dispersing efficiency and on aging stability.
