PRESSURE-SENSITIVE ADHESIVES HAVING A TEMPERATURE-STABLE ADHESIVE POWER

摘要

The disclosure relates to a heat-curable adhesive composition that can be cross-linked by heating, said composition comprising between 20 and 85 % of a polyurethane comprising 2 terminal groups of the hydrolysable alkoxysilane type of formula (I) : wherein the variables are as defined in the specification. The composition also comprises between 15 and 80 % of a compatible tackifying resin; and between 0.01 and 3 % of a cross-linking catalyst. The disclosure also relates to a self-adhesive support coated with the cross-linked adhesive composition, which is used for manufacturing self-adhesive labels and tapes.
