Cohedur®

Cohedur bonding agents promote adhesion between elastic rubber and inelastic-but-durable material such as reinforcing carcasses or steel cords, which are combined to make long-lasting tires, conveyor belts, hoses, rubberized fabrics, containers, etc.


Adhesion between rubber and reinforcing materials is very important for composites such as tires, conveyor belts, V-belts, hoses, rubberized fabrics, and containers. These products consist of an elastomeric matrix and a reinforcing material. The elastomeric matrix tears easily but can be stretched, which provides elasticity. The reinforcing material does not tear easily and does not stretch, which provides dimensional stability.


Cohedur® bonding agents enhance adhesion by physical and chemical interaction. These direct bonding agents are mixed into the rubber compound, which can be applied directly to the substrate. Without bonding agents, adhesion is based only on mechanical interaction due to the penetration of the rubber between the fibers.
