L-W6500 can also be used as a crosslinking agent for water-based polyols and most neutral hydroxy free water-based polymer dispersions (such as polyurethanes, polyvinyl acetate resins, polyacrylates and synthetic rubber dispersions) to improve their performance in all aspects. 2/2 After the addition of YL-W6500, the two-component paint to be used must be used during the activation period. The activation period is affected by the polymer content and other components (e.g. resins, thickeners, plasticizers, etc.), and in many dispersions, the end point of the activation period (usually several hours) does not show up as a gel phenomenon.
