Waterborne Polyurethanes for Water-Based Synthetic Leather
A Top PUDs supplier in the World

Water-based synthetic leather has the advantages of environmental protection, free of harmful chemicals, abrasion resistance, cold resistance, breathability, aging resistance, soft texture, and great appearance. It has become the most ideal choice to replace solvent-based synthetic leather and dermal leather. Waterborne polyurethanes make excellent coatings for synthetic leather. Depending on the application, they can be used on their own or in combination with acrylic emulsions to find just the right balance between cost and performance.

At SIWO US Inc, we’ve developed specific grades that are ideal for synthetic leather coating. They are inherently flexible because they don’t contain any plasticizers that may migrate or become volatile over time. Additionally, they offer incredible abrasion resistance and have superior tensile strength.

Our focus on research and development in waterborne polyurethane products has made them possible to develop cutting-edge solutions. We offer base coat and topcoat finishes for a premium leather. Our topcoat waterborne polyurethanes come with excellent finish and abrasion resistance, while base coats offer unmatched softness and flexibility. Get the right balance between toughness, flexibility, and shine with our custom solutions for synthetic leather.

We have the abilities of designing and providing waterborne polyurethane materials for your product lines of water-based synthetic leather.

They are easy to mechanically foam, and mainly used in synthetic leather foaming layer. Their films have excellent resilience, excellent resistance to zigzag, excellent alkali resistance, low temperature resistance, dry and wet stripping. The melting temperature SiwoPUD®-SWU can reach more than 200℃ (without crosslinking).

Aromatic waterborne polyurethane SiwoPUD®-F945, 45% solid content, NMP and DMAC free, for synthetic leather base. It is based on polyether, and exhibits softness, resilience, good water resistance, good NaOH and hydrolysis resistance.
