Adhesives with permanent tack are widely used in medicine. Due to its high strength and fast curing, the adhesive provides long-term fixation of medical devices, so it is commonly used for skin fixing of medical devices such as dressings. Currently, among the polymer bases for adhesive systems, polyisobutylene, polysiloxane, urethane and acrylic polymers or mixtures thereof are most often used. However, in this work, the properties of adhesive adhesives of permanent tack for medical purposes based on natural rubber were studied. As fillers used: apple pectin, pine rosin and beeswax. In this work, the determination of the strength during delamination was carried out, microphotographs of a sample of a permanent adhesive adhesive and its components were taken using a scanning electron microscope on a scale of: 150; 500; 1000; 3000; 5000, IR spectroscopy was also performed.
