Preparation and adhesion properties of waterborne polyurethane-coated resin for synthetic leather
Abstract
The purpose of this study is to evaluate the adhesive properties of waterborne polyurethane-coated resin for synthetic leather by omitting the primer and the preparation of waterborne polyurethane-coated resin for synthetic leather with excellent adhesion by omitting the pre-treatment process. First, after synthesizing flexible polyurethane dispersion using Poly (tetrahydrofuran)(PTMG, Mw=2,000) and Isophorone diisocyanate(IPDI), coating resins have been created by adding various silane coupling agents, an additive, and tested of their characteristics. As a result, a polyurethane dispersion for synthetic leather with fine adherence strength (Ethylene vinyl acetate(EVA, mid-sole) : 2.9 kgf/cm, rubber(out-sole) : 3.4 kgf/cm) has been developed without use of primer.
