CRAYVALLAC® SLX 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 very high viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.

CRAYVALLAC® EXTRA is a high performance, micronised amide wax rheology modifier suitable for high-solids and solvent-free applications with very high robustness. It is especially recommended in 2K epoxy primers for its high temperature tolerance.CRAYVALLAC® EXTRA overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body and that were maximised when activation was performed at high temperatures.

CRAYVALLAC® PC is a micronised hydrogenated castor oil derivative surface enhancing additive for powder coatings based on PRIMID, hybrid and TGIC technologies. CRAYVALLAC® PC is easily incorporated using conventional pre-mixing techniques prior to extrusion. The use of CRAYVALLAC® PC leads to a substantial improvement in the appearance of the final cured powder coating. This improvement is due to CRAYVALLAC® PC enhancing the flow, levelling and degassing processes during cure. This is the result of CRAYVALLAC® PC greatly reducing the melt viscosity during this critical levelling stage in the cure cycle. This viscosity reduction also enhances the performance of other additives such as acrylic levelling agents and the degassing agent benzoin. CRAYVALLAC® PC works well in both clear and pigmented powder coating systems based on PRIMID, Hybrid and TGIC technologies.

ACRYSOL™ DR-5500 is a new associative thickener that delivers the same performance as ACRYSOL RM-5, but without the use of APEO surfactants. ACRYSOL™ DR-5500 provides excellent gloss, film build, and flow in latex paints. Being both APEO-free and solvent-free, ACRYSOL™ DR-5500 is ideally suited to meet the latest regulatory requirements for waterborne paints and coatings. This product enhances high shear (ICI Cone and; Plate) viscosity, resulting in coatings with high film build characteristics, improving hiding and appearance. Additional benefits for manufacturers include minimal roller spatter and the full realization of gloss potential in latex paints. Since ACRYSOL™ DR-5500 uses hydrophobically-modified alkali-soluble chemistry, it offers a high degree of resistance to bacterial and enzymatic attack, ensuring long-term paint viscosity stability.

CRAYVALLAC® LA-377 is a modified urea dissolved in DMSO. CRAYVALLAC® LA-377 is a pourable liquid rheology modifier for post addition to water-based coatings such as water-dilutable alkyds and acrylic emulsions. It was developed to ensure particular suitability for metal coating as its formula is lithium chloride-free. CRAYVALLAC® LA-377 should be added to the coating as a slow stream under low to medium shear conditions to ensure sufficient dispersion. Although efficient stirring is required to ensure homogeneity, elevated temperatures are not required for activation and the use of excessive shear should be avoided.

CRAYVALLAC® SF is a proprietary amide-modified hydrogenated castor oil rheology modifier with an enhanced tolerance to temperature and solvent strength suitable for a variety of different solvent-based systems e.g. aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to other hydrogenated castor oil based rheology modifiers, CRAYVALLAC® SF is more tolerant to strong solvents and high processing temperatures due to the presence of its unique performance enhancing amide. The activation process constitutes the conversion of the CRAYVALLAC® SF particles to an interacting network of fibre-like particles. It is this network that gives rise to the final coating’s shear thinning rheology. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.
