HDI Waterborne WanHua 278
Product Description?
Aquolin 278 is a water dispersible polyisocyanate based on hexamethylene diisocyanate(HDI). In combination with waterborne polyurethane, polyacrylate, etc., it can be used for water-borne coatings. Thanks to its low viscosity and ease of handmixing, Aquolin 278 can be used to prepare “solvent-free hardener” in order to produce ultralow VOC coatings. After addition of Aquolin 278, the ready-to-use mixture must be used within the pot life.
