PARALOID™ B-67MT Resin is an alkyd-compatible acrylic resin designed to have good compatibility with long-oil alkyds. The addition of PARALOID™ B-67MT Resin to alkyds, oils, or varnishes produces coatings of improved hardness, faster drying speed, better color and gloss retention, and improved hold out and brushing characteristics.

PARALOID™ B-67 100% Resin is particularly compatible with medium and long-oil alkyds, drying oils, and oleoresinous varnishes. When used to modify these materials, coatings with improved hardness, faster drying speed, and better retention of color and gloss result. Hold out and brushing characteristics are also improved.

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.

ACRYSOL™ DR-2 Rheology Modifier is a synthetic, liquid thickener that offers a low cost/high performance alternative to cellulosic thickeners in interior flat latex paints. ACRYSOL™ DR-2 Rheology Modifier offers application and feel properties very similar to medium grades of cellulosic thickeners. It also has outstanding spatter resistance. ACRYSOL™ DR-2 Rheology Modifier is easy to handle and incorporate into the paint and is formulated to resist microbial contamination.

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® LA-150 is a new pourable liquid rheology modifier supplied in Dimethylsulfoxide (DMSO) for post addition to solvent based systems.CRAYVALLAC® LA-150 is a post-addition rheology modifier composed of a modified urea dissolved in DMSO. When added to the final system, the DMSO is diluted and the modified urea crystallizes out as very fine fibres which build into a three-dimensional interacting network. It is this network that gives rise to the system’s shear thinning rheology and time dependent viscosity recovery. The result is excellent control of sedimentation combined with ease of application. Immediately following application, where low shear conditions again predominate, the system’s viscosity undergoes a time dependent recovery as the network re-establishes itself. This time dependency is known as thixotropy and enables the final system to attain very good levelling.

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.

ROVACE™ 9100AF Copolymer Emulsion is a new emulsion that offers the same performance as ROVACE 9100 Copolymer Emulsion, but is manufactured without the use of APEO surfactants. ROVACE 9100AF Copolymer Emulsion is a 55% solids vinyl/acrylic binder for interior flat and semigloss paints. This new generation of binder offers exceptional scrub resistance and stain removal and its consistent particle size minimizes variability in paint production. ROVACE 9100AF Copolymer Emulsion is compatible with today's prevalent use of rheologymodifiers that show very good application properties, flow and leveling characteristics. In our lab testing and evaluations we have not seen any differences in formulation parameters, application properties or dry film property differences between ROVACE 9100 and ROVACE 9100AF Copolymer Emulsion.

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.

HP1717 - Polystar Soya Long Oil Alkyd is a long oil alkyd made with soya oil in low odour mineral spirits. It has been formulated for use in wood and metal coatings and architectural enamels. This product exhibits low yellowing, good gloss, and good overall appearance.

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.
