1、Typical
Properties
l Widely used
in dry lamination between various types of films, especially for aluminum foil
packaging, with excellent adhesion fastness.
l It has
excellent resistance of heat and chemical stability,
composite materials can be resistant 30min cooking at 121 ℃.
l It has very high safety for food packaging manufacture on account of
without any aromatic isocyanate compound in main component.
l We can spray it very easily with high solid content and low
viscosity so that we can reduce production cost and increase productivity.
l Very few intermediate product processes and easy-controlled technics
guarantee steady quality.
