This document introduces additives and formulations for hand and surface disinfection purposes. BYK itself does not manufacture disinfectants or raw materials for disinfection, but BYK rheology additives are effective in imparting viscosity to mixtures of alcohol based on ethanol or isopropanol and water. Disinfectants and surface cleaners have the advantage of being able to stay in one place for a long time if their viscosity does not decrease with water. This is where the functionality of BYK rheology additives comes into play. 【Featured Products】 <Ethanol based> ■LAPONITE-RD ■RHEOBYK-HV 80 ■RHEOBYK-7410 ET ■RHEOBYK-7420 ES ■RHEOBYK-7410 ET/RHEOBYK-7420 ES *For more details, please refer to the PDF document or feel free to contact us.

"DISPERPLAST-1180" is a highly effective wetting and dispersing agent. It is suitable for high-filled filler systems that can cause limitations in general processing aids and standard wetting and dispersing agents. Not only does it make it easier to reduce formulation costs by increasing the filler addition amount, but it also improves the quality of the final product. In particular, it is suitable for high-quality laminate systems such as PVC design flooring (LVT). [Features] <During the processing of PVC drive blends/compounds> ■ Improvement of resin processability ■ Rapid plasticization speed ■ Good dispersion of molten materials ■ Increased melt strength ■ Ability to increase filler addition amount under specified processing conditions *For more details, please refer to the PDF document or feel free to contact us.

"BYK-3566" is a newly added acrylic-based surface modifier in the BYK product line, based on macromer technology. It increases the surface energy of the dried film. The relatively long silicone macromer chains are a key feature, providing a very strong orientation at the paint/air interface, resulting in excellent effects. Furthermore, the long chains also impart anti-beading properties. 【Features】 - Increase in surface energy of the cured film due to orientation at the paint/air interface - Good wettability and adhesion to the topcoat - Improved leveling properties - Slight anti-beading properties - Suitable for water-based, solvent-based, UV, and 100% systems *For more details, please refer to the PDF document or feel free to contact us.

"BYK-3456" is a fluorine-free silicone-based additive. It significantly reduces dynamic and static surface tension, providing sufficient wettability even on rough, porous substrates. It is effective at both the interface and surface with the substrate, simultaneously improving wettability and leveling properties. This additive shows compatibility with many resins and demonstrates hydrolytic stability over a wide pH range. 【Features】 - Excellent wettability on porous substrates such as wood - Improved wettability and good leveling on substrates - Reduction of dynamic surface tension - Hydrolytic stability over a wide pH range - Prevention of cratering, fish eyes, and framing - High compatibility with many resins *For more details, please refer to the PDF document or feel free to contact us.

"BYK-3450/BYK-3451" is a water-based surface modifier that significantly reduces surface tension without increasing slip and improves wettability on very low polarity substrates. Based on a trisiloxane developed by BYK, the two additives "BYK-3450" and "BYK-3451" provide good wettability even on very difficult substrates, as well as significant expansion performance. Compared to general-purpose silicone surfactants, these two additives contribute little to foam stabilization, thus improving processability and paintability. 【Features】 ■ Excellent diffusibility and wettability ■ Significant reduction in surface tension ■ Minimal foam stabilization compared to general-purpose silicone *For more details, please refer to the PDF document or feel free to contact us.

Our company handles the liquid defoamer 'BYK-1680'. The generation of bubbles is generally undesirable not only during the manufacturing of paints, printing inks, and plastic materials but also in many processes. Defoamers and anti-foaming agents prevent and remove the occurrence of bubbles, improving manufacturing processes and achieving excellent surfaces and suitable product characteristics. This product is particularly suitable for water-based construction materials formulated with polycarboxylate ether-based concrete admixtures. 【Features】 ■ Very good solubility in water and PCE-based polymer solutions ■ No cloudiness or layer separation in concrete admixtures ■ Long-term stability in concrete admixtures even at high temperatures ■ Very good spontaneous and controlled long-lasting defoaming properties ■ Improved fluidity ■ Can be added to the final system without restrictions *For more details, please download the PDF or feel free to contact us.
