Water-Based PU Emulsion For Top Layer Of Synthetic Leather
Description
WQ provides water-based PU emulsion for both top and bonding layers which is a great solution to instead of solvent based into solvent-free process. It can be used for the decoration of luggage, clothing, shoes, vehicles and furniture. water-based PU resin and non-woven fabrics used as raw materials for artificial leather called water-based PU synthetic leather (water-based synthetic leather). It shows a kind of essential beauty, which embodies the taste of “plain face to sky”
