CRAYVALLAC® SL is a high performance micronised amide wax rheology modifier designed for the high temperature manufacture of moisture curing methoxysilanes systems, where processing temperatures typically lie within the range 90 – 115°C. CRAYVALLAC® SL 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® WS-4700 is a 40% active dispersion of polyethylene wax in isopropanol. The low viscosity and high active content of this dispersion, together with freedom from dust, assist the efficiency of manufacturing processes. CRAYVALLAC® WS-4700 provides the formulator with the means of controlling the frictional characteristics of a coating as well as enhancing its surface protection properties.

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® WN-3025 is a finely micronized hard polyethylene wax. CRAYVALLAC® WN-3025, with its well-balanced performance properties, is of particular interest to the ink formulator. Here it provides an excellent balance between high rub resistance and good slip, yet with minimal detraction from gloss.

CRAYVALLAC® PA3 XAF 20 is an alcohol-free pre-activated amide wax supplied in xylene. It is a rheology modifier in paste form with high efficiency (optimum sag resistance and viscosity).CRAYVALLAC® PA3 XAF 20 is supplied in the form of crystalline fibres. In a coating system, these fibres form an interacting network. This network gives rise to the shear thinning rheology of the final coating. 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® 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® A-72-A2-60-A is a binder used in CASE ingredients.

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.

CRAYVALLAC® LA-250 is a modified urea dissolved in DMSO and is a pourable liquid rheology modifier for post addition to low polarity solvent based coatings. CRAYVALLAC® LA-250 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.

CRAYVALLAC® LV is a high performance, micronised amide wax rheology modifier suitable for very high-solids and solvent-free applications.CRAYVALLAC® LV overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body. Consequently, coatings formulated using CRAYVALLAC® LV exhibit an enhanced performance such as controlled flow behavior, ease of application and excellent sag resistance. Its very high efficiency even when activated allows to reach very strong shear thinning that can result either in very high sag resistance or interresting balance between viscosity and sag resistance. Therefore CRAYVALLAC® LV is for instance highly recommended in the case of solvent free coatings with relatively low viscosity. It prevents the use of specific equipment for the application that are necessary with more viscous solvent-free coatings.

CRAYVALLAC® WW-1001 is a 40% active dispersion of polyethylene wax in water. The low viscosity and high active content of this dispersion, together with freedom from dust, assist the efficiency of manufacturing processes. CRAYVALLAC® WW-1001 provides the formulator with the means of controlling the frictional characteristics of a coating as well as enhancing its surface protection properties.

CRAYVALLAC® 60P is a solid powder wax consisting of fine particles of oxidized polyethylene recommended to prevent irreversible hard settling. The fine nature of this dispersion means that CRAYVALLAC® 60P is easily incorporated and activated in coating systems. It is mainly used in industrial and maintenance coatings where its primary function is to provide pigment suspension without any increase in the apparent viscosity. CRAYVALLAC® 60P can generally be used in most solvent-based formulations. Typical applications are epoxy primers, vinyl primers, anti-fouling paints, road marking paints and chlorinated rubber coatings.

CRAYVALLAC® WF-9200 is a micronised PTFE modified polyethylene wax.
