Durability

Polyurethane adhesives based on aliphatic isocyanates show exceptional durability thanks to:   The lack of phenyl group in the aliphatic isocyanates backbone It makes polyurethane adhesives prepared from aliphatic isocyanates far less prone to oxidation than those based on aromatic isocyanates.   The superior resistance of the urethane bond when exposed to UV light Aliphatic-based polyurethane adhesives will, as a result, keep their excellent mechanical properties and unchanged color and transparency during a longer time than when using aromatic isocyanates.
