By adding it to the hard coat agent, flexibility can be imparted!
"8BR" is a UV-curable urethane acrylic polymer with an acrylic polymer as the main chain and urethane polymer (oligomer) as the side chain. The composition and ratio of acrylic and urethane can be adjusted, allowing for the modification of physical properties (hardness, elongation, etc.). It can be used as a polymer material (acid-free) that imparts flexibility to hard coat agents. 【Features】 ■ Can impart flexibility by adding to hard coat agents ■ Excellent tack-free properties due to its polymer type, reducing curing shrinkage ■ Superior adhesion to various film substrates ■ Composition and ratio of acrylic and urethane can be adjusted ■ Physical properties (hardness, elongation, etc.) can be modified *For more details, please refer to the related link page or feel free to contact us.
