Bomar Oligomers® BR-7432GB

1 of 88 products in this brand
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. BR-7432GB also has low MeHQ for nail gel polish applications.
