Rubber To Metal Bonded Components
                     RUBBER TO METAL BONDED COMPONENTS – 
CRITICAL TO SEVERAL INDUSTRIES
Rubber to metal bonding or adhesion is a very 
common practice in several industries since 
such processes are required for various 
applications. 
Be it for sticking silicone parts or rubber parts 
to hard or very hard metal parts, the adhesion 
processes used in rubber to metal bonding is 
same but with varying levels of adhesion. 
Rubber to metal bonded products are 
especially prevalent in the automotive and 
engineering industries, wherein such 
processes help to insulate noise and offer 
protection to the components. 
There are essentially three components of any 
rubber to metal bonding.
Rubber
Bonding agents
Substrate
In certain components, adhesion is 
required only for assembly purposes 
whereas others require very close controls. 
The levels of adhesion required for any 
rubber to metal bonded component 
depends upon the following factors:
Type of application intended
Types of metal
Preparation of surface
The number and types of nonmetallic 
inserts
Conditions of curing
Type of adhesive used
The processes of rubber to metal bonding 
generally include:
Preparation of the surface to be bonded by 
cleaning it thoroughly
Preparation of inserts by methods of 
blasting or degreasing
Vulcanization of the prepared inserts for 
obtaining the desired adhesion
More commonly, adhesive cements are used for 
rubber to metal bonding.
 The adhesives used for such bonding are either 
solvent based or water based. 
Solvent based adhesives are low on hazardous 
air pollutants. 
It is important that the adhesive for each of the 
applications be chosen keeping in mind the 
rubber materials and the metals used in the 
process. 
It is also to be remembered that the adhesive 
chosen should be able to withstand the potential 
use and wear and tear of the components that 
are to be bonded.
Adhesives are available both in single coat and 
double coat system, each catering to specific 
needs. Two coat systems are generally used in 
instances wherein the component is used in 
harsh conditions.
