Title: RADIATION-CURABLE AQUEOUS URETHANE (METH)ACRYLATE DISPERSIONS BASED ON ISOCYANATES, (METH)ACRYLATE MONOMERS AND AN INTERNAL EMULSIFIER
Abstract:
The invention relates to radiation-curable aqueous urethane (meth)acrylate dispersions based on diisocyanates, (meth)acrylate monomers and an internal emulsifier. The internal emulsifier is radiation curable and comprises maleic anhydride units and alkylene oxide units. The dispersion results in coatings being scratch resistant and resistant to chemical substances.
