ECCO Crosslinker AP-900 Isocyanate ECCO Crosslinking / Coupling / Curing Agents >> Isocyanate Acrylics/ Acrylates PU - Prepolymers Polyvinyl Alcohol (PVOH) SEALANT ADHESIVE >> Water-based ECCO CROSSLINKER AP-900 Waterborne blocked isocyanate dispersion for crosslinking carboxylated resins and fluoropolymers. ECCO CROSSLINKER AP-900 is an effective crosslinker to provide greatly improved performance of waterborne acrylics, urethane, polyvinyl alcohols and fluoropolymers. As a resin modifier for paints, inks, coatings and adhesives we offer the following benefits: Greatly improves abrasion resistance. Increases adhesion to substrates. Enhances water, solvents and chemical resistance. Improves durability of fluoropolymers to washing and dry cleaning. Recommended start levels of ECCO CROSSLINKER AP-900 is 2.0-5.0% based on total resin. Waterborne blocked isocyanate dispersion. Used as an effective crosslinker to provide greatly improved performance of waterborne acrylics, urethane, polyvinyl alcohols and fluoropolymers for one-component adhesives and sealants. Improves abrasion resistance. Increases adhesion to substrates. Enhances water, solvents and chemical resistance. Use level: 2.0-5.0% based on total resin.
