  • Application & Dosage

      Typical addition level is 5 – 7 parts addition to 100 parts of wet polymer dispersion.

40% Aqualink U-HT is an aqueous dispersion of an isocyanate dimer which has been chemically blocked to make it stable in the presence of water. It has been formulated to have improved stability over Aqualink U and is recommended where finished adhesive is stored for prolonged periods. It has been designed for use in combination with polyurethane dispersions and other water based polymers in the manufacture of one-part water-based heat activated adhesives such as membrane and 3D press applications.
