BR-1043MB
BR-1043MB: Difunctional Aliphatic Polyether Urethane Methacrylate Oligomer
BR-1043MB is a bio-based polyether urethane methacrylate oligomer with a majority percentage of bio-based content. This oligomer provides excellent low-temperature flexibility, elasticity, and excellent dynamic properties and rebound with a lower viscosity versus similar polyether chemistries. The oligomer exhibits a higher degree of heat resistance vs other polyether oligomers. The high bio-based backbone and methacrylate functionality make this an excellent candidate for consumer applications with low irritancy requirements.
