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.

RHOPLEX® AC-337N is designed for use in semi-transparent stains. This binder provides an extremely hydrophobic film, leading to excellent water resistance and reduced liquid water permeability. RHOPLEX® AC-337N Acrylic Emulsion has been developed to react more efficiently with associative thickeners, leading potentially to lower formulation cost. RHOPLEX® AC-337N Acrylic Emulsion also shows improved color acceptance and alkyd compatibility. The 100% acrylic backbone ensures the high standard of tint retention, crack resistance, chalk resistance, and alkali resistance. The outstanding adhesion technology will ensure excellent adhesion to wood. The in-can clarity makes it possible to prepare transparent and semi-transparent stains with more attractive application properties than conventional alkyd emulsion or acrylic emulsion based stains.

RHOPLEX® WL-81, waterborne, acrylic polymer is specifically designed for the formulation of clear and pigmented ambient or forced-air-dry industrial lacquers. Coating systems based on this polymer are suitable for use on a variety of substrates and offer a number of key benefits currently provided by solvent borne industrial lacquers, but without the flammability, odor, or other problems inherent with such systems.

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® PA3 XAF 20 is an alcohol-free pre-activated amide wax supplied in xylene.

ACRYSOL™ WS-68 Emulsion is a thermosetting acrylic polymer supplied as a colloidal dispersion in water. When formulated with monomeric melamine resins, it facilitates the formulation of industrial baking enamels that offer excellent spray characteristics and film properties.

SS-07 is energy conservation materials, environmental and safety. Non-toxic, no smell and free of heavy metals.

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® ULTRA is a pure polyamide especially recommended in 2K epoxy primers for its robustness. CRAYVALLAC® ULTRA is a micronised amide wax rheology modifier offering very good recoatability for ambient curing solvent-based epoxy coatings. CRAYVALLAC® ULTRA has been designed to overcome those difficulties which exist with older type organo-wax rheology modifiers e.g. seeding, false-body and migration of readily dissolved species to the surface. Consequently, when used in strong solvent systems, coatings formulated using CRAYVALLAC® ULTRA offer an enhanced performance and very good recoatability.

CRAYVALLAC® REV is a new high performance micronised amide wax rheology modifier offering perfect recoatability for regular, high solids and solvent-free coatings. CRAYVALLAC® REV has been designed to provide reliability and efficiency in a wide range of coatings. As other CRAYVALLAC® modifiers, it overcomes technical constraints such as seeding, false-body and migration of readily dissolved species to the surface. Even used in strong solvent systems, coatings formulated using CRAYVALLAC® REV offer an enhanced performance and very good recoatability.

CRAYVALLAC® OPTIMA is a high performance, micronised amide wax rheology modifier suitable for high-solids and solvent-free applications recommended for its ease of activation and smooth viscosity recovery (good levelling). CRAYVALLAC® OPTIMA overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body without the need of increasing the temperature of activation. Its smooth viscosity recovery will help to achieve high film thickness without compromising a good levelling.

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® 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® 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.
