UV/EB Oligomer
BR-7432GB
BR-7432GB: Difunctional Aliphatic Polyester Urethane Acrylate Oligomer
BR-7432GB, an aliphatic polyester urethane diacrylate, formulates into applications requiring adhesion to various substrates and applications such as thermoforming resistant coatings where toughness and flexibility are required. BR-7432GB provides excellent balance of weathering, solvent resistance, tensile strength, and adhesion properties. BR-7432GB is an incredibly tough, elastomeric material with similar mechanical performance to cast urethanes, and can provide excellent impact resistance and weatherability to formulations. BR7432GB also has low MeHQ for nail gel polish applications.
