ROBOND™ L-90M is a water-based acrylic adhesive used primarily to laminate flexible substrates together. The laminations are used in flexible packaging.
ROBOND™ L-90M can be used on it's own as a one component adhesive, or it can be used in combination with Coreactant CR 9-101 as a two component system to improve shear strength, chemical resistance, and heat resistance. It is used to laminate treated polyolefins, PVDC coated substrates, metalized films, and nylon. These laminations are typically used in food packaging and bottle label applications. ROBOND™ L-90M has incredibly fast bond development when used with CR 9-101 and laminations can be slit in as little as 5 min after lamination. This as well as a long pot life and low foam development allow for increased efficiency of water-based lamination operations.
