Coating &
Lamination

Shuang Bang has been producing waterproof and breathable PU membrane for decades. We successfully develop PU membranes for different applications. To customize the products easier, develop new product faster, and provide more competitive price to our customers, we use the PU resins we manufacture.

The first wet process PU coating production line was added since 2009, and later started to product 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 water. 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 microporous PU film is smoother and richer than others.

Transfer Lamination

In transfer lamination process, functional agents and color pigments are added to customize functional products. The performance of transfer lamination product can achieve waterproof (JIS L1092B): 20,000/ M.V.P (JIS L1099B1): 20,000.
