Recently, There has been increased requirement to high performance adhesive. By the trends, high performance adhesive which has high durability, hydrolysis, environmentally friendly and has been attracted interest in market. A lot of solvent are used to make adhesive, e.g. DMF, 2-butanone(MEK), toluene, and they were confirmed as cancer caused or suspicious chemical by clinical researcher. However, physical properties solvent based polyurethane are very excellent, evaporated a lot of corrosive gas included DMF, 2-butanone, toluene during adhesive manufacturing In this study, water-bone polyurethane with high performance developed to overcome these problem, and develop environmentally friendly adhesive made of them. |
