Abstrakt: The effect of thickness and reinforcement on the properties of the mastic layer of an incongealable sealant based on butyl rubber is studied, depending on the nature of the glued substrate. It has been established that the nature of the substrate affects the adhesive properties of the mastic. The effect of the thickness of the mastic layer on the adhesive properties is most pronounced in determining the bond strength by the tear-off method. The influence of the nature of the substrate on adhesion to the mastic layer is considered from the standpoint of acid–base interactions. The possibility and expediency of reducing the thickness of the incongealable mastic layer based on butyl rubber of the sealing coating of roofing purpose to the level of 0.5 mm without loss of quality is established. It is shown that the reinforcement of sealing coatings based on highly filled butyl rubber does not affect their vapor permeability and strength during peeling and tearing. [ABSTRACT FROM AUTHOR]
