Bomar Oligomers® BR-582

BR-582 is a 2.4 average functional aliphatic polyether urethane acrylate. As with other BR-500 series materials, BR-582 is designed to offer a balance of benefits between toughness and flexibility. While only slightly lower in tensile strength and hardness than BR-571, BR-582 has almost double the total elongation at break. BR-582 responds quickly to UV cure, owing to its elevated functionality.
