Q1: What is the primary function of DAOTAN VTW 1265/36WA in polyurethane coatings?
A: DAOTAN VTW 1265/36WA is a water-dispersible polyurethane resin designed to serve as a film-forming binder or co-binder in high-performance waterborne PU systems, contributing to enhanced flexibility, abrasion resistance, and substrate adhesion without compromising environmental compliance.
Q2: Is DAOTAN VTW 1265/36WA compatible with common waterborne acrylic dispersions?
A: Yes — it is formulated for good compatibility with a broad range of waterborne acrylics, vinyl acetate copolymers, and other anionic or non-ionic dispersions, enabling hybrid formulations that balance cost, performance, and regulatory requirements.
Q3: How should DAOTAN VTW 1265/36WA be incorporated into a coating formulation?
A: It is typically added during the let-down stage under gentle agitation, after pigments and thickeners have been dispersed. Avoid high-shear mixing post-addition to preserve particle integrity and colloidal stability.
Q4: Does this resin require a crosslinker for optimal performance?
A: While it delivers good single-component film properties, performance attributes such as chemical resistance, hardness development, and thermal stability are significantly enhanced when used with suitable water-dispersible polyisocyanate crosslinkers — especially in demanding industrial or automotive refinish applications.
