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.

CRAYVALLAC® MT is a micronised amide modified hydrogenated castor oil rheology modifier for solvent-based and solvent-free systems. CRAYVALLAC® MT is suited to systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to the most basic hydrogenated castor oil based rheology modifiers, CRAYVALLAC® MT is more tolerant to stronger solvents. CRAYVALLAC® MT particles are converted upon activation into an interacting network of fibre like particles. This network 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.

TYLOSE MH 10015 P4 is a water-soluble, non-ionic, modified methyl hydroxyethyl cellulose powder with standard etherification. It provides fast consistency development, very high sag resistance and water demand, moderate water retention and influence on cement hydration, and high heat stability. This grade is ideal for use in cement tile adhesives.

TYLOSE MB 10008 P4 is a water-soluble, non-ionic, highly etherified, modified methyl hydroxyethyl cellulose powder. It provides moderate consistency development, very high sag resistance and water demand, moderate water retention and influence on cement hydration, and low heat stability. This grade is ideal for use in cement tile adhesives.
