Q1: What is the primary function of DAOTAN TW 6464/36WA in polyurethane systems?
A: DAOTAN TW 6464/36WA is a water-dispersible polyurethane resin designed primarily as a crosslinker or reactive modifier to enhance film hardness, chemical resistance, and mechanical durability in aqueous PU coatings and adhesives.
Q2: Is DAOTAN TW 6464/36WA compatible with common waterborne acrylic dispersions and other polyurethane dispersions?
A: Yes — it is formulated for broad compatibility with standard anionic and non-ionic waterborne acrylics, polyester dispersions, and other aliphatic polyurethane dispersions, enabling stable blends without phase separation under typical formulation conditions.
Q3: How should DAOTAN TW 6464/36WA be incorporated into a formulation?
A: It is typically added during the late-stage mixing phase, after pH adjustment and under gentle agitation, to avoid shear-induced destabilization. Pre-dilution with deionized water may be recommended depending on the base dispersion’s sensitivity to ionic strength.
Q4: Does this resin require forced curing or elevated temperatures to achieve full performance?
A: While ambient cure develops usable properties over time, optimal crosslink density and final film performance are generally achieved with mild thermal treatment—typically between 60 °C and 90 °C for 10–30 minutes—depending on film thickness and substrate.
