Abstract
A heat-activated process for forming a patch for plastic and leather-like materials employs a protective coating around the patched area to avoid damage due to the heating step. The protective coating cures to form a continuous insulating sheet prior to the heating step and is easily removable at the conclusion of that step.
Claims9
A process for repairing a damage in plastic or leather-like materials in which a heat-curable film-forming patching compound is applied to the damage, covered by a graining paper and heated therethrough with a flat hot surface at a temperature and for a time to cure the patching compound, including the steps of coating the undamaged material around said damage with a heat-insulating paste comprising materials which cure in the presence of a catalyst to form a heat insulating film, curing said heat insulating paste, and then adding said patching compound.
A process for repairing a damaged area in plastic or leather-like materials comprising the steps of placing a backing material behind said damaged area, spreading a curable film-forming heat-insulating paste including a catalyst over the surface of the material to be repaired leaving uncovered the area thereof immediately around the damage, curing said heat-insulating paste applying a heat-curable film-forming patching compound to the damaged area after said heat-insulating paste is cured, covering the patching compound with a vinyl-release graining paper and applying a flat hot surface to heat the patching compound through the graining paper for a time and at a temperature to cure the patching compound.
