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.

Hostavin® 3058 liq is a non-basic low molecular weight hindered amine light stabilizer (HALS), 100% liquid, characterized by its excellent solubility, broad compatibility in all kind of liquid paints, with low volatility and excellent stabilization efficiency.

Castorwax® is a wax like compound obtained by the controlled hydrogenation of pure castor oil. The principle constituent is glycerol tri-(12-hydroxystearate), also known as opalwax. Castorwax® is a hard, brittle, high melting point wax that is insoluble in most organic solvents but is highly compatible with most resins and waxes.

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.

Hostanox® P-EPQ powder is a highly efficient phosphorus based secondary antioxidant, which reduces the thermo-oxidative degradation of polymers and the development of undesired color (yellowing) during processing. The main advantages of Hostanox® P-EPQ powder are its high thermal stability and high solubility in polymeric materials as well as its broad compatibility in coating polymers.

Licowax® PE 520 powder is a polyethylene wax.

AERODISP® WF 7620 is an aqueous 20% dispersion of a functionalized fumed aerosil

Bermocoll® EBS 351 FQ is a non-ionic, water soluble cellulose ether with enhanced enzyme resistance. It improves the consistency, the stability, and the water retention of water based products.

ACRYSOL™ RM-6000 Rheology Modifier is a nonionic urethane rheology modifier based on solvent-free1 technology offering improved efficiency without sacrificing key performance properties. The efficiency in both the medium shear and high shear range results in good flow and leveling with high film build while maintaining good sag resistance. ACRYSOL™ RM-6000 Rheology Modifier has demonstrated utility in a broad range of emulsions, including the “newer generation”, low-VOC types such as RHOPLEX™ SG-30 Acrylic Emulsion and RHOPLEX™ ML-300 Acrylic Emulsion.

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.

VANCRYL® 450 is a high solids colloidal dispersion that can be neutralized with ammonia or other alkaline materials to provide an outstanding vehicle for corrugated printing ink applications. VANCRYL® 450, at 40% solids, reduces the cost in ink systems based on pre-neutralized colloidal acrylics. VANCRYL® 450 exhibits excellent black pigment grinding, and high drink in corrugated systems. This polymer, when neutralized with ammonia at 10% solids in water, has a viscosity of 150 cP, or about 40 seconds on a # 2 Zahn cup. It provides excellent transfer and printing at this low, economical solids level. Neutralization can be easily accomplished by a simple mixing of 100 parts polymer wet, 95 parts water, and 5 parts ammonia. This mixture produces a 20% solids colloidal emulsion with a viscosity of 6000 to 9000 cP. It can be used in black pigment dispersions as well as color letdowns for corrugated inks. VANCRYL® 450 is also an effective thickener for other formulations based on acrylic and styrenated acrylic polymers.

ACRYSOL™ DR-1 Thickener is a synthetic, liquid thickener that offers a low cost/high performance alternative to cellulosic thickeners in interior flat latex paints. ACRYSOL™ DR-1 Thickener provides application and feel properties very similar to medium grades of cellulosic and hydrophobically modified HEC thickeners with excellent resistance to roller spattering and improved leveling in most formulations. ACRYSOL™ DR-1 Thickener is easy to handle and incorporate during the paint manufacturing process and is highly resistant to microbial attack. ACRYSOL™ DR-1 Thickener is part of the Designed Rheology product line which provides customized rheology based on key components.

Bermocoll® E 481 FQ is a non-ionic, water soluble cellulose ether. It improves the consistency, the stability, and the water retention of water based products.

Bermocoll® EHM 200 is an associative non-ionic, water-soluble cellulose ether that improves the rheological properties of water-based paints.
