BYK Additives & Instruments


03.01.2017 - CERATIX 8561, CERATIX 8563 and CERATIX 8566

CERATIX 8561, CERATIX 8563 and CERATIX 8566 - NMP-free Wax Additives for Excellent Effect Pigment Orientation in Solvent-borne Coatings

The proven wax additives CERATIX 8461, CERATIX 8463 and CERATIX 8466 contain a small quantity (< 0.5 %) of N-methylpyrrolidone (NMP). However, there are increasing demands to manufacture effect pigment coatings that are entirely free from NMP. To meet these market requirements, BYK has optimized the manufacture of these CERATIX wax additives so that it can produce NMP-free products. The new NMP-free wax additives CERATIX 8561, CERATIX 8563 and CERATIX 8566 are an alternative to the established products and offer an equivalent substitute. They are recommended for usage in automotive, general industrial, and leather coatings (CERATIX 8561).

03.01.2017 - CERAFLOUR 955, CERAFLOUR 958 and CERAFLOUR 959

CERAFLOUR 955, CERAFLOUR 958 and CERAFLOUR 959 - wax additives for fine uniform textures in powder coatings

CERAFLOUR 955 is a pure PTFE (Polytetrafluorethylene)-type which is highly effective even at low dosage providing intense texture effects along with deep mat finishes. CERAFLOUR 958 and CERAFLOUR 959 are both PTFE-modified PE (polyethylene) waxes that allow for a wide range of texture and matting levels from semi- to deep-mat finishes. All three products have an optimal price-performance ratio and, hence add great economic benefit to powder coating formulations.

28.11.2016 - BYK-1788

BYK-1788 - VOC-free and Silicone-free Polymer Defoamer for Solvent-borne, High-solid and Solvent-free Systems. Particularly Suitable for 100 % UV Systems

100 % systems and particularly UV-curing coatings are difficult to defoam as a result of their high processing viscosity and lack of solvent. However, their economic and environmental friendly formulation makes them popular for use in wood, furniture, leather, and general industrial coatings as well as thermoset applications. Along with high effectiveness, clear systems in particular require good defoamer compatibility to guarantee excellent transparency and high gloss. The well-balanced interaction of effectiveness and compatibility makes the new additive BYK-1788 particularly suitable for non-pigmented systems. BYK-1788 is silicone- and VOC-free and does not introduce any solvents to the formulation. However, in solvent-borne coating systems and those with high solids, BYK-1788 demonstrates its full spectrum of performance.

28.11.2016 - BYK-1799

BYK-1799 -  VOC-free Silicone-containing Defoamer for Solvent-borne, High-solid and Solvent-free Systems. Particularly Suitable for 100 % UV Systems

100 % UV systems generally display a higher processing viscosity as a result of a lack of solvents. If the formulation also contains matting agents and pigments, defoaming becomes difficult. For example, to be effective at high application speeds such as during roller application, it is necessary to have a spontaneous and highly effective defoamer. The new BYK-1799 has these properties and is effective even at an extremely low dosage. Adding BYK-1799 also effectively prevents both micro- and macrofoam. The main fields of application are UV wood and furniture coatings, and UV printing inks. However, it also perfectly defoams solvent-borne and high solid systems.

24.10.2016 - AQUACER 1013 and AQUACER 1039

AQUACER 1013 and AQUACER 1039 - Ecolabel-Compliant Wax Additives for Aqueous Coatings

As a reaction to the revision of different European ecolabels and to the reclassification of certain chemicals as well as tighter limit values for using chemicals that are classified as hazardous substances, BYK is developing additives that comply with the recent standards and can be used without any restrictions. This meets the users´ requirements for easy adaption of their current formulations to the latest safety and environmental directives. AQUACER 1013 is a HDPE-based wax emulsion for improving the surface protection in aqueous coatings and printing inks as well as in aqueous care products and polishes. The wax emulsion AQUACER 1039 is of paraffinic nature and improves the surface characteristics of aqueous coatings and printing inks.

25.07.2016 - DISPERBYK-2205

DISPERBYK-2205 - Solid wetting and dispersing additive for a multitude of solvent-borne applications and UV printing inks

DISPERBYK-2205 is an extension to BYK’s product family of solid and very effective wetting and dispersing additives. As a result of the optimal molecular weight distribution the additive is highly compatible in a variety of systems; the reduced amine value leads to an almost neutral character and enables it to be used in acid catalyzed systems. DISPERBYK-2205 offers a low handling viscosity and a perfect pigment stabilization combined with a high gloss and low haze in industrial, coil, automotive, wood and furniture coatings. In printing ink applications it can also be used for medium-polarity systems and even UV systems.

06.07.2016 - BYK-326

BYK-326 - High-solid, moderately active surface additive for improving the leveling of solvent-borne, solvent-free and aqueous systems

If the broadest possible compatibility is required, for instance to also be compatible with aqueous systems, it would be preferable to use a medium-polarity additive. The new BYK-326 provides a balanced profile and ideally completes the BYK range with regard to universal application in all systems. It has medium polarity and displays moderate activity in reducing surface tension, which produces excellent leveling results.
