Abstract:
Temperature switchable adhesives formed by combining a pressure sensitive adhesive, which does not exhibit temperature switchable properties, with a crystallizable oil are described. These temperature switchable adhesives exhibit a sharp reduction in peel strength when the temperature is raised above the switching temperature. The adhesive properties of these adhesives may be readily tuned by adjusting the ratio of the elastomer, tackifier, and the crystallizable oil, and by choosing different crystallizable oils. The temperature switchable adhesives have use in medical, consumer, and industrial applications.
