Products

AEROSIL® COK 84 is a formulated product with highly dispersed fumed aluminium oxidein the ratio of 5:1.

ACRYSOL™ RM-895 is a thickener compatible with polyurethanes (PU).

CRAYVALLAC® SLW is a high performance micronized amide wax rheology modifier designed for manufacture of one component Silyl-Terminated-Polymer based adhesives and sealants, especially for highly filled systems (demanding applications, High-Tack systems for instance).

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.

CRAYVALLAC® PA3 S 12 is used in gelcoats and wood coatings. It is compatible with wood substrates and features anti-settling, cost-effectiveness, ease of incorporation, excellent filler and pigment suspension, good leveling, high thixotropy, recoatability, sag resistance, and transparency. The product functions as a rheology modifier in CASE ingredients.

CRAYVALLAC® SLX is a high performance micronised amide wax rheology modifier designed for the low temperature manufacture of moisture curing methoxysilane systems, where processing temperatures typically lie within the range 60 - 90°C. 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.

ACRYSOL™ RM-845 Rheology Modifier is a new generation, solvent-free, APEO-free, non-ionic product. ACRYSOL™ RM-845 is based upon patented and proprietary technology that enables it to contain 27% solids yet be provided at a low viscosity to allow facile pumping and pouring. ACRYSOL RM-845 Rheology Modifier builds mid-shear Stormer viscosity more efficiently than existing KU-builders. It is recommended for acrylic- and styrene/acrylic-based latex coating formulations. ACRYSOL™ RM-845 Rheology Modifier offers excellent flow and leveling, as well as gloss development, for both interior and exterior paints. It imparts a rheological profile to architectural and industrial coatings very similar to that of ACRYSOL RM-825, but with the benefit of no added solvent, allowing for ultra-low VOC formulations.

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.

HECTGEL RDS is a modified synthetic hectorite. It can hydrate and swell in the water to form the colorless and transparent colloid with low viscosity. When its concentration in water is 10%, it can still keep a good fluidity for a long period.

HECTGEL RD is a synthetic layered silicate consisting of Li, Mg and Si. Its structure is constituted by two layers of Si-O tetrahedron with one layer of Mg-O octahedron. It can hydrate with water and swell to form clear and colorless colloidal dispersions. Highly thixotropic gels can be formed at concentrations of 2% or more and these gels demonstrate highly shear thinning behavior. HECTGEL RD is used where a shear sensitive waterborne gel structure is desired, having high viscosity under low shear and low viscosity when exposed to high shear. Upon removal of shear the gel viscosity is quickly recovered.

WANNATE® HT-400 is used in paints and coatings as a binder and resin, hardener, intermediate, and thinner. It is compatible with polyacrylates, polyester polyols, and polyurethanes (PU).

AEROSIL® R 805 Silicas is a fumed silica after-treated with organosilane. It provides utmost transparency.

AEROSIL® 300 is a hydrophilicfumed silica with a specific surface area of 300 m²/g. Itprovides a verystrong rheologicaleffect.

Suspengel 325 Plus is used across multiple markets, including agriculture and feed, ceramics and refractory, paints and coatings, paper and pulp, sealants and caulks, and water treatment.

CRAYVALLAC® LA-150 is a new pourable liquid rheology modifier supplied in Dimethylsulfoxide (DMSO) for post addition to solvent based systems.CRAYVALLAC® LA-150 is a post-addition rheology modifier composed of a modified urea dissolved in DMSO. When added to the final system, the DMSO is diluted and the modified urea crystallizes out as very fine fibres which build into a three-dimensional interacting network. It is this network that gives rise to the system’s shear thinning rheology and time dependent viscosity recovery. The result is excellent control of sedimentation combined with ease of application. Immediately following application, where low shear conditions again predominate, the system’s viscosity undergoes a time dependent recovery as the network re-establishes itself. This time dependency is known as thixotropy and enables the final system to attain very good levelling.
