CRAYVALLAC® ANTISETTLE CVP is used in caulks, solventborne coatings, and greases. It features anti-settling, good leveling, high shear thinning, high thixotropy, recoatability, and sag resistance. The product functions as a rheology modifier in CASE ingredients.

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® 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.

ACRYSOL™ ASE-60 Alkali Soluble Anionic Thickener is an acid containing, acrylic emulsion copolymer. As such, when the emulsion is diluted with water and neutralized with a base, the polymer becomes soluble. Under these conditions, the emulsion clarifies and becomes highly viscous. ACRYSOL™ ASE-60 Thickener is effective at increasing low shear rate (Brookfield) viscosity, resulting in coatings that have highly shear thinning characteristics.

HFGEL 120-N is an organophilic clay optimized for use primarily in aliphatic and other non-polar to medium polarity solvent-based systems. HFGEL 120-N belongs to the newest generation of high performance organoclays, being easy to disperse and self-activating. It can be added at any point in the manufacturing process and can be used to correct finished batches. HFGEL 120-N imparts viscosity increase, sag control and prevents settling of pigments and fillers.

CRAYVALLAC® 60X is used in epoxies (EP) and vinyls. It is applied in anti-fouling coatings, chlorinated rubber coatings, primers, and solventborne coatings. The product provides anticaking, recoatability, and sag resistance.

CRAYVALLAC® MT is used in solventborne coatings, as well as solventless and high solids coatings. It features anti-settling, high thixotropy, recoatability, and sag resistance. The product functions as a rheology modifier in CASE ingredients.

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® 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® 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® 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.

HFGEL 120-B12 is an organophilic clay designed for use in aromatic and polar systems such as those containing aromatic hydrocarbons, alcohols, ketones, glycol ethers, and esters. It does not require use of a chemical activator to reach optimal efficiency. HFGEL 120-B12 can be incorporated at any point in the manufacturing process using common processing equipment. HFGEL 120-B12 provides stable rheology and helps control sag and pigment settling.

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® PC is a micronised hydrogenated castor oil derivative surface enhancing additive for powder coatings based on PRIMID, hybrid and TGIC technologies. CRAYVALLAC® PC is easily incorporated using conventional pre-mixing techniques prior to extrusion. The use of CRAYVALLAC® PC leads to a substantial improvement in the appearance of the final cured powder coating. This improvement is due to CRAYVALLAC® PC enhancing the flow, levelling and degassing processes during cure. This is the result of CRAYVALLAC® PC greatly reducing the melt viscosity during this critical levelling stage in the cure cycle. This viscosity reduction also enhances the performance of other additives such as acrylic levelling agents and the degassing agent benzoin. CRAYVALLAC® PC works well in both clear and pigmented powder coating systems based on PRIMID, Hybrid and TGIC technologies.

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.
