SiwoPUD®-PUD-6993S

SiwoPUD®-PUD-6993S is an aliphatic polycarbonate waterborne polyurethane dispersion featuring a small particle size and a solids content of 32 ± 1%. It forms a clear, transparent coating film with a soft feel, making it a suitable resin for leather coating and finishing applications that require flexibility, strong adhesion, and a smooth surface appearance.

One of its key advantages is its excellent adhesion to leather, helping provide reliable coating performance on leather substrates. The resulting film also offers excellent dry and wet rub resistance, supporting surface durability against repeated rubbing and handling. These properties make PUD-6993S a useful option for formulators developing water-based leather coatings that require both a soft-touch finish and good resistance to everyday wear.

PUD-6993S also provides outstanding flex resistance and low-temperature resistance. Its high elongation of 1000–1100% contributes to film flexibility, helping the coating withstand repeated bending and deformation. These characteristics are particularly valuable in applications where coated leather materials need to maintain their appearance and coating integrity under flexible-use conditions.

With its combination of transparency, soft feel, leather adhesion, dry and wet rub resistance, and flexibility, SiwoPUD®-PUD-6993S is a suitable waterborne polyurethane resin for high-performance leather coating and finishing formulations.
