Waterborne polyurethane dispersions（PUDs）for steel surface treatment／PCM
UBE offers waterborne polyurethane dispersions（PUDs）for steel surface treatment／PCM. The PUDs provide highly durable coatings with excellent corrosive resistance, chemical resistance, weathering resistance and hydrolysis resistance. The PUDs can be used for various steel plates such as hot-dip galvanized steel sheet（GI）, electro-galvanized steel sheet（EG）, hot-rolled steel sheet（SPH）and cold-rolled steel sheet（SPC）.
Features
- High adhesion on various steel sheets
- Excellent chemical resistance and corrosive resistance
- Excellent weathering resistance and hydrolysis resistance
