BR-1044MB
BR-1044MB: Difunctional Aliphatic Polyether Urethane Methacrylate
BR-1044MB is a biobased polyether urethane methacrylate with 84% of bio-based content. Compared to similar petrochemical-based materials, BR-1044MB combines a lower viscosity with similar flexibility, elasticity, and softness. This resin brings excellent resiliency with impact properties to formulations along with improved compatibility of all components.
