Q1: What are the key advantages of using a waterborne leather color paste versus solvent-based alternatives?
A: Domestic Waterborne Leather Color Paste offers improved workplace safety, reduced VOC emissions, and easier handling in standard aqueous coating systems. It eliminates the need for flammable solvent storage and simplifies wastewater treatment compliance in typical tannery or finishing operations.
Q2: Is this product compatible with common leather topcoats and binders?
A: Yes — it is formulated to integrate well with acrylic, polyurethane, and styrene-acrylic dispersions commonly used in domestic leather finishing. Compatibility testing under actual process conditions is recommended due to formulation variability across binder systems.
Q3: How should the color paste be dispersed into a leather coating formulation?
A: Add gradually under moderate agitation during the aqueous phase mixing stage. Avoid high-shear dispersion unless validated, as excessive shear may destabilize the pigment dispersion. Pre-dilution with a portion of the base medium can aid uniform incorporation.
Q4: Does this color paste require special storage conditions?
A: Store in tightly sealed containers at temperatures between 5 °C and 35 °C, away from direct sunlight and freezing conditions. Prolonged exposure to high humidity or temperature extremes may affect viscosity stability and dispersion integrity over time.
