Polyurethane adhesives used in flexible packaging show a good adhesion on various types of
materials (plastic films, aluminum, cardboard...) and their low viscosity
makes them suitable for roller applications.
When applications require heat & humidity resistance, transparency and non-yellowing upon ageing properties,
aliphatic isocyanates will be of good help to formulate suitable adhesives.
In addition, no hazardous amines are released when aliphatic
isocyanates are used to formulate polyurethane adhesives.
