-Aqualink U is an aqueous dispersion of an isocyanate dimer which has been chemically blocked to make it stable in the presence of water.
-Aqualink U has been designed for use in combination with polyurethane dispersions in the manufacture of one-part water-based adhesives for membrane and 3D press applications.
-Aqualink U acts as a crosslinker.
-Aqualink U is miscible in water and exhibits barely perceptible odor.
-Aqualink U is recommended for many types of polyurethane dispersions (PUD'S).
-Aqualink U can also be used to formulate water-based alternatives to solvent borne systems.
-Aqualink U should not be used with strong acids, strong bases and nitrates.
