摘要:
A semi-aqueous ethylene-vinyl alcohol coating composition that is a stable, homogeneous solution which is capable of being easily applied to a substrate to form a multilayer structure at room temperature, by spray, rod, gravure, or other mechanical means. Upon evaporation of the volatile components, this coating solution leaves a clear, homogeneous film comprising EVOH. The film resists degradation and discoloration during the lifetime of the structure, and upon incineration or recycling does not evolve harmful acids into the environment.
摘要:
An aqueous dispersion comprising an ethylene-vinyl alcohol copolymer with an ethylene content of 15 to 65 mole % as a dispersoid and a saponified ethylene-vinyl ester copolymer containing ionic groups and having an ethylene content of 10 to 70 mole % and a degree of saponification of 80 mole % or above as a dispersion stabilizer. The dispersion has excellent stability during storage or use thereof and a high solid content, and gives a coating film having excellent gas barrier properties after being dried.
