SURFACE TREATMENT METHOD FOR A SUBSTRATE USING DENATURED URUSHIOL DERIVED FROM TOXICODENDRON VERNICIFLUUM

摘要

The present invention relates to a surface treatment method for a substrate using denatured urushiol derived from Toxicodendron vernicifluum, and more specifically to one in which the reactivity of the hydroxyl group in urushiol extracted from fresh Toxicodendron vernicifluum is removed such that when it is used as a UV coating material for substrates such as steel sheets it can not only exhibit high level antimicrobial properties but can also exhibit outstanding surface-appearance and functional properties including a far-infrared radiating effect, an electromagnetic-wave shielding effect, a corrosion-resistance enhancing effect, a high crosslinking reaction rate while using a low content of photoinitiator, and outstanding surface glossiness and scratch resistance.
