Abstract
A study was made of the influence of temperature (80–295 K) on the adhesion of PE coatings to metals (resistance to separation of the metal foil substrate). It is shown that a fall in the test temperature and an increase in the rate of separation leads to a several-fold increase in the resistance to separation and alters the type of failure of adhesive joins. The degree of increase in separation resistance depends on the thickness of the PE coating, and on the nature and thickness of the foil substrate. The effectiveness of factors making for better adhesion of PE (oxidation, filling, addition of peroxide compounds, and other factors) is impaired when the test temperature is reduced. The paper also contains data on the adhesion of other polymers, and possible explanations of the observed phenomena are discussed.
