PUD (polyurethane dispersion) for artificial leathers

Product Description: is an anionic aliphatic aqueous polyurethane dispersion designed specifically for use as a tie coat in the manufacturing of artificial leathers (synthetic leathers) to provide excellent performance: good initial tacky property, excellent peel strength, and excellent yellowing resistance.  It has great cost performance.  It does NOT contain APEO, tin, or organic amine neutralizers.       

Uses:  as the adhesive tie coat layer in the manufacturing of polyurethane (PU), and polyvinylchloride (PVC) artificial leathers.      

Product General Properties*:

Gaia-PUD 802

Product Description: is an anionic aliphatic aqueous polyurethane dispersion designed specifically for use as a foam (body) coat in the manufacturing of polyurethane (PU) artificial leathers (synthetic leathers) to provide excellent performance: excellent rebound elasticity, good resistance to thermal tackiness, non-tacky, and yellowing resistance. It has excellent cost performance.  It does NOT contain APEO, tin, or organic amine neutralizers.       

Uses:  as the foam (body) coat layer in the manufacturing of PU artificial leathers.  Use cautions: 1). Do not mix this resin under strong shear force; when pigment is to be added, pre-mix the pigment well before mixing with the resin;  2). Use deionized water if dilution of the resin is required.
