Abstract
Rubber compositions are disclosed which are capable of exhibiting superior adhesion and high water resistance in bonding rubbers to brass and to organic fiber cords and also to different rubbers. Such bonding characteristics can be obtained by the use of specified amounts of a selected class of organic sulfur-containing compounds combined with sulfur-curable rubbers, silica, resorcin donors and methylene donors. Hoses are also disclosed which have these compositions applied as adhesive layers.
