Bomar Oligomers® BR-1043MB

1 of 88 products in this brand
BR-1043MB is a bio-based polyether urethane methacrylate oligomer with a majority percentage of bio-based content. This oligomer provides lowtemperature 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.
