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 remain 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.

GARAMITE-7305 is a rheology additive that exhibits superior properties compared to conventional organic affinity phyllosilicates (organic clays). Conventional phyllosilicates require high shear forces and polar activators (surfactants) to promote dispersion during formulation. In contrast, GARAMITE-7305 can be easily dispersed and activated with moderate shear forces in solvents and binders. By using GARAMITE-7305, it becomes possible to achieve high viscosity formulations in low shear areas, resulting in excellent sedimentation prevention effects and anti-syneresis properties. When shear forces are applied, viscosity significantly decreases, greatly improving application characteristics.

★The Importance of Rheology in High Solid Content Polyurethane Formulations High solid content polyurethane (HS PU) is gaining popularity as an alternative to solvent-based systems (DMF coagulation process) and PVC plastisol. HS PU often exhibits relatively high viscosity at room temperature, but it has been observed that when cured in a high-temperature oven at 150-170°C, the viscosity significantly decreases. This phenomenon can potentially affect leveling properties and foaming ratios when using chemical blowing agents. By using 【GARAMITE】, it is possible to suppress the viscosity decrease in the oven.
