DISPERCOLL U 56 is an anionic high-molecular-weight polyurethane dispersion that is particularly well suited for applications with low thermal activation temperatures and is therefore particularly well suited for use on temperature-sensitive substrates. DISPERCOLL U 56 has outstanding bonding properties on most synthetic and natural materials used in industries. It provides excellent adhesion to substrates even at low temperatures without comprising on the bond strength. The product is thermally stable and has high resistance to plasticizers, grease and oil which are commonly present in many applications. DISPERCOLL U 56 can be customized to meet specific technical requirements by adding additives like resin dispersions, emulsifiers and thickeners.
