BYK-3565    Acrylate Surface Additive to Increase Surface Energy, with Anti-cratering Properties

Currently not available to the North American market.

The requirements on modern coating systems are constantly increasing. In many systems, properties such as leveling, substrate wetting, and anti-cratering can still be achieved with traditional silicone or acrylate surface additives. However, if good recoatability or adhesion is required at the same time, these products reach their limits.

The new BYK-3565 is the logical further development of BYK's macromer-modified acrylate additives and can meet these complex requirements. Its special modification means that BYK-3565 orientates itself at the coating surface and increases the surface energy of the dried coating film. The recoatability or adhesion of subsequent coatings are improved at the same time. BYK-3565 is recommended for use in aqueous, solvent-borne, and 100 % systems, with an extra anti-cratering effect mainly in the aqueous coatings.

31.03.2017 - DISPERBYK-2080 and DISPERBYK-2081

DISPERBYK-2080 and DISPERBYK-2081    Wetting and Dispersing Additives for Aqueous Systems with No Negative Impact on Water, Corrosion and Stain Resistance

Currently not available to the North American market.

Wetting and dispersing additives for aqueous coating systems always possess a certain hydrophilic character. Essentially, they are needed to wet, disperse and stabilize pigments and fillers. However, the hydrophilic structure of the additives also continues to have an impact in the cured coating film. This may cause key film properties such as water, corrosion and stain resistance to be impaired. DISPERBYK-2080 and DISPERBYK-2081 are new additives that are particularly suited to aqueous anti-corrosive primers, direct to metal systems, and aqueous wood and furniture coatings.
They offer significant viscosity reduction and a good deflocculation, especially of inorganic pigments, fillers and anti-corrosive pigments, without impairing the coatings´ resistance.

22.03.2017 - DISPERBYK-2158 and DISPERBYK-2159

DISPERBYK-2158 and DISPERBYK-2159    Wetting and Dispersing Additives for Excellent Dispersion and Stabilization of Silica-based Matting Agents to Produce Deep-matt UV-curing and Conventional Solvent-borne Coatings Currently not available to the North American market.

Radiation curing is a technology that represents a particular challenge – from careful raw material selection to perfectly tailored application and curing equipment. In addition, it is common to use treated or untreated silica-based matting agents for the matting of coatings. However, high quantities of silica are required, which causes a significant increase in viscosity. To both satisfy the technical requirements and achieve an optimum application viscosity, BYK has developed the new additives DISPERBYK-2158 and DISPERBYK-2159. Their special structural design enables perfect interaction both with treated and untreated silica-based matting agents to achieve consistently deep-matt coatings with optimum, slightly thixotrope viscosity profiles. DISPERBYK-2158 and DISPERBYK-2159 are compatible with all common monomers and oligomers.

21.03.2017 - BYK-1781

BYK-1781 Silicone Defoamer for Aqueous Systems to Eliminate Micro-foam Generated During Application

A well balanced-defoamer, the interaction of compatibility and efficiency is the guarantor for an easy application and a high quality of the final coating. The new BYK-1781 includes all these features. The balanced silicone/polyether ratio leads to an excellent compatibility in a variety of aqueous coating systems e.g. pure acrylics, UV-systems and 2-pack PU-systems without a negative impact on clarity, haze and cratering. In addition the high efficiency of BYK-1781 makes it extremely suitable for difficult application methods such as HVLP, Airless and Airmix to eliminate the micro-foam that occurs in the coating film.

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.
