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® WF-1039 has been especially designed to give textured finishes to polyester and hybrid powder coating systems. This texturing agent is easily incorporated using conventional premixing techniques prior to extrusion.

CRAYVALLAC® LA-350 is used in acrylics and alkyds for waterborne coatings. It features high shear thinning, high thixotropy, improved anti-sagging properties, recoatability, sag resistance, and viscosity control. The product functions as a rheology modifier in CASE ingredients.

CRAYVALLAC® PF is a modified micronised hydrogenated castor oil rheology modifier specially designed to facilitate the incorporation in powder form for betteractivation and easier handling. The activation process is the conversion of the CRAYVALLAC® PF fine particles to an interacting network of fibers. It is this network that gives rise to the final system’s shear thinning rheology. This shear-thinning behavior 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® PF is suitable for a multitude of applications.

CRAYVALLAC® TW-1340 is a 38% active dispersion of modified polyethylene wax in isopropanol.

CRAYVALLAC® PA3 BA 20 is a HAPs-free pre-activated amide wax supplied in a mixture of butyl acetate and alcohol. It is a rheology modifier in paste form with high efficiency (optimum sag resistance and viscosity).CRAYVALLAC® PA3 BA 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® WN-1265 is a micronised amide wax.

CRAYVALLAC® SUPER is a high performance, micronised amide wax rheology modifier suitable for a wide range of solvent-based, high-solids and solvent-free applications. CRAYVALLAC® SUPER overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body. Consequently, coatings formulated using CRAYVALLAC® SUPER exhibit an enhanced performance such as controlled flow behavior, ease of application and excellent sag resistanceIts smooth viscosity recovery will help to achieve high film thickness without compromising a good levelling.

CRAYVALLAC® PA4 BA 20 is a HAPs-free rheology modifier pre-activated amide wax supplied in a mixture of butyl acetate and alcohol. It is a rheology modifier in paste form with enhanced transparency, excellent anti-sagging and anti-settling properties.CRAYVALLAC® PA4 BA 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® PA4 X 20 is a rheology modifier pre-activated amide wax supplied in a mixture of xylene and alcohol. It is a rheology modifier in paste form with enhanced transparency, excellent anti-sagging and anti-settling properties.CRAYVALLAC® PA4 X 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® 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® 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.

CRAYVALLAC® PA4 WDA 12 is a pre-activated amide wax supplied in a mixture of mineral spirit (D60) and alcohols. Under paste form for post addition to solvent-based low polarity coating systems, it provides a very simple and direct mean of introducing shear-thinning rheology with thixotropic viscosity recovery to coating formulations. It is a softer version than CRAYVALLAC® PA3 WDA 20 with enhanced ease of incorporation. It is also a very cost efficient alternative to organoclays. The shear-thinning characteristic provides a very high viscosity under the low shear rates and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application. Immediately following application, the coating’s viscosity undergoes a time dependent recovery as the network re-establishes itself. This time dependence is known as thixotropy and enables the final coating to attain very good levelling.
