BR-573M: Difunctional Aliphatic Polyether Urethane Methacrylate

BR-573M is a tin-free difunctional aliphatic polyether urethane methacrylate. BR-573M is an excellent candidate to consider for use in tough 3D printing resins or nail gel applications. As a primary oligomer, BR-573M offers excellent properties of hardness, adhesion and optical clarity. As a co-oligomer, BR-573M can be used to improve an existing formulation’s adhesion and impact resistance. This product has low skin sensitivity and good optical properties.
