PROTECTIVE ENCLOSING OF ELONGATE SUBSTRATES

摘要

Polymer-in-monomer adhesives containing peroxides which are curable by contact with an activator catalyst are used to adhere protective polymer sheeting to heat-absorbing substrates, especially metal pipelines. Heat-recoverable sheeting, preferably 10 to 50% recoverable, carrying curable mixtures of acrylic polymer in acrylic monomer plus peroxide, is preferred, with metal salt and/or amine activator catalysts being preapplied to the pipeline or other substrate.
