RUBBER TO METAL BONDED
                     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 with stand 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.
