CRAYVALLAC® EXTRA is a high performance, micronised amide wax rheology modifier suitable for high-solids and solvent-free applications with very high robustness. It is especially recommended in 2K epoxy primers for its high temperature tolerance.CRAYVALLAC® EXTRA overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body and that were maximised when activation was performed at high temperatures.

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.

XIBOND® 335 is a reactive additive to improve the blend morphology of polymer blends; this additive is a random terpolymer of styrene, maleic anhydride and N-Phenylmaleimide.

CRAYVALLAC® SL is a high performance micronised amide wax rheology modifier designed for the high temperature manufacture of moisture curing methoxysilanes systems, where processing temperatures typically lie within the range 90 – 115°C. CRAYVALLAC® SL 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 very high viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.

K-FLEX® 850P is a blend of dipropylene glycol dibenzoate and diethylene glycol dibenzoate specifically designed for vinyl applications with economy as a focus. It is similar in composition to K-FLEX® 850P (diethylene glycol dibenzoate rich). By composition it is a non- phthalate. As a high solvator for vinyl it can be formulated alone or in blends for plastisols as well as melt compounded vinyl.

EBECRYL® 8809 is a difunctional aliphatic urethane acrylate that does not contain any intentionally added organic tin compounds, heavy metals*, hydroquinone (HQ) or methyl ether of hydroquinone (MEHQ). (Please note that quinones are present in many raw materials, so the overall quinone content is reduced, but not zero in EBECRYL 8809.) Films of EBECRYL 8809 cured by ultraviolet light (UV) or electron beam (EB) exhibit excellent exterior durability, toughness, and resistance to yellowing. EBECRYL LEO 10501 is present at 5% in this product.

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® WW-1001 is a 40% active dispersion of polyethylene wax in water. The low viscosity and high active content of this dispersion, together with freedom from dust, assist the efficiency of manufacturing processes. CRAYVALLAC® WW-1001 provides the formulator with the means of controlling the frictional characteristics of a coating as well as enhancing its surface protection properties.

CRAYVALLAC® WS-4700 is a 40% active dispersion of polyethylene wax in isopropanol. The low viscosity and high active content of this dispersion, together with freedom from dust, assist the efficiency of manufacturing processes. CRAYVALLAC® WS-4700 provides the formulator with the means of controlling the frictional characteristics of a coating as well as enhancing its surface protection properties.

XIBOND® 185 is a reactive additive to improve the blend morphology of polymer blends. This additive is a random copolymer of styrene and maleic anhydride.

SURFYNOL® 104 BC is a multifunctional surfactant providing combined dynamic wetting and molecular defoaming in water borne coatings and inks.

RE:CHEMISTRY MOVE200 is a pure ester-based Solvent. 58% Biogenic Carbon (derived from agricultural waste) according to ASTM D6866-20. Readily biodegradable. Non-flammable, Non-combustible and Low volatile. Classified as Non-corrosive, Non-sensitizing and Non-toxic. Miscible in conventional organic solvents and water. Butyl Levulinate is a GRAS.

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® WW-9500 is a 35% active dispersion of modified polypropylene wax in water.The low viscosity and high active content of this dispersion together with freedom from dust assist the efficiency of manufacturing processes.CRAYVALLAC® WW-9500 provides the formulator with the means of controlling the frictional characteristics of a coating as well as enhancing its surface protection properties.It also retards the settlement of pigments and assists in their redispersion.

CRAYVALLAC® PA4 WDA 12 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 very simple and direct mean of introducing shear-thinning rheology with thixotropic viscosity recovery to coating formulations. It is a softer version than CRAYVALLAC® PA3 WDA 20 with enhanced ease of incorporation. It is also a very cost efficient alternative to organoclays. The shear-thinning characteristic provides a very high viscosity under the low shear rates 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.
