UV-CURABLE COMPOSITION FOR A TRANSPARENT COLOR COATED SHEET, CAPABLE OF OFFERING ADHESIVE PROPERTY, CORROSION RESISTANCE, AND BENDING PROPERTY, AND A STEEL SHEET USING THE SAME

摘要

PURPOSE: A UV-curable composition is provided to improve productivity by offering corrosion resistance, shock resistance, scratch resistance, adhesive property, and bending property and to obtain an environment-friendly steel sheet without using a solvent.;CONSTITUTION: A UV-curable composition includes modified epoxy acrylate oligomer 25~45 parts by weight, urethane and acrylate oligomer 10~25 parts by weight, reactive acryl monomer 32~48 parts by weight, photoinitiator 5~10 parts by weight, and additive 1.3~2.7 parts by weight. The reactive acryl monomer is comprised of monofunctional reactive acryl monomer 25~35 parts by weight and difunctional reactive acryl monomer 7~13 parts by weight.;COPYRIGHT KIPO 2010
