CRAYVALLAC® SUPER

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

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.

CRAYVALLAC® PC

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.
