Licocene® PE MA 4351 fine grain is a highly grafted maleic anhydride polyethylene wax with advantageous physical properties e. g. for powder coating applications. The maleic anhydride modified polyethylene creates structured surfaces in combination with titanium dioxide. The roughness depends on the ratio of titanium dioxide to Licocene® PE MA 4351 fine grain. Licocene® PE MA 4351 fine grain is used as an efficient coupling agent for glass-, wood-, natural fibre and inorganic filled PE compounds.

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.

“AEROSIL® E 812 is a fumed silica post-treated with an organosilane (HMDS). It has a high specific surface area and exhibits exceptional hydrophobicity. The material is very easy to disperse

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® PA3 WDA 20 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 shear-thinning rheology with thixotropic viscosity recovery to coating formulations. In coating systems, its crystalline fibres form an interacting network which gives rise to the shear-thinning rheology of the final coating. It 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. 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.

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.

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.
