Q1: What is the primary function of DAOTAN TW 6474/37WA in polyurethane systems?
A: DAOTAN TW 6474/37WA is a waterborne polyurethane dispersion designed to serve as a reactive crosslinker or performance modifier, enhancing film hardness, chemical resistance, and mechanical durability in two-component (2K) and hybrid PU coatings.
Q2: Is DAOTAN TW 6474/37WA compatible with common aqueous polyurethane dispersions and acrylic emulsions?
A: Yes — it exhibits good compatibility with a broad range of waterborne polyurethane dispersions and acrylic emulsions, enabling formulation flexibility in hybrid binder systems for industrial and architectural coatings.
Q3: How should DAOTAN TW 6474/37WA be incorporated into a coating formulation?
A: It is typically added during the let-down stage under mild agitation. Pre-dilution with deionized water may be used to aid dispersion, and pH adjustment is generally not required unless blending with highly sensitive components.
Q4: What are the recommended storage conditions for optimal shelf life?
A: Store in tightly sealed original containers at temperatures between 5 °C and 30 °C, away from freezing and direct sunlight. Prolonged exposure to temperatures below 5 °C may cause irreversible viscosity changes or phase separation.
