Direct Coating

Since 2009, Shuang-Bang added the first wet process PU coating production line, and started to produce micro-porous PU products. By directly coating the functional PU resins on fabric, then dipping into water tank, then high concentration of DMF will permeate into low concentration one’s. With the exchange process between DMF and water, PU resin gradually forms microporous structure on the substrate. This process makes the products have good waterproof and moisture permeable performance. In general, the touch of micro porous PU film is smoother and richer than others.
