Rheology control agent for high solid content polyurethane that suppresses viscosity reduction in high-temperature ovens【GARAMITE】.
★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. Overview of 【GARAMITE-1958】 - Pseudoplastic - Suitable for solvent-based and solvent-free systems - No polar activation required - Non-dripping - Patented - Allows for easy and rapid formulation
