Rubber coating is one of the most widely used processes of coating in various appliccations. Coating is applied onto or impregnated into a substrate or an object for protective, decorative or functional purposes. Rubber coating application is a very important consideration in the selection of coating material. This type of coating is used on many elastomeric components like seals, gaskets, o-rings, stoppers and plungers, which are used in a variety of industrial applications like electronics, medical, automotive, military industries etc.

The purpose of the coating and the kind of rubber required for coating are chosen on the basis of the technological equipment. The design of rubber coating application place is chosen considering both the equipment exploitation and equipment design departments. You can coat anything with a flexible rubber coating by spraying, brushing or dipping. Rubber coatings provide a barrier against the leaching of elastomeric bi-products, and at the same time protect surfaces from organic solvents and inorganic reagents, acids and solutions.

Buying tips When selecting appropriate rubber coating, the following should be considered: Temperature Friction Material being coated

Types of rubber used in rubber coating

• Silicone Rubber (SiR)
• Neoprene
• Ethylene Propylene Diene Monomer (EPM, EPDM)
• Natural Rubber
• Viton
• Butyl Rubber (IIR)
• Hypalons

Rubber as a coating material
Rubber is a preferred material for coating application because of two reasons:

• Rubber is resisted to mechanical wear and tear.
• Rubber is resisted to the influence of strong aggressive environment.

Advantages of Rubber Coating

• It is flexible.
• It won't crack, chip or become brittle.
• Coating insulates from electrical shock, vibration, heat.
• Coating nullifies sound.
• It provides safe, non-slip comfort and control.
• It is durable.
• Rubber coating resists weather, chemicals, impact and abrasion.
• Improved lubricity which means lower coefficient of friction.
• Reduces stickiness.
• Rubber coating gives protection from oils, dirt and contamination.
• It has excellent dielectric strength.

Applications of rubber coating

• Rubber roof coating
  An important application of rubber coating is rubber roof coating. Rubber roof coating is used to repair or recoat rubber roofs as well as to reseal protrusions in the roof. This type of coating can also be applied over galvanized steel, bituminous built-op roofs, concrete, wood, polyurethane foam and asphalt roof shingles. Rubber roof coating is applied wherever a flexible durable and long lasting protection is required. Rubber Roof Coating is applied using a brush, roller or spray equipment.
  
• Rubber Spray Coating
  Rubber spray coating or specialty coating is the answer for applications that require on-site repair. Huge tanks, launder systems, and equipment with intricate detail work all use specialty coating. Sprayable urethane is produced to protect all surfaces and equipment which are exposed to any kind of abrasive and corrosive environments. These rubber coatings are easy to repair and they form and add reinforcement to other highly durable protective linings. Sprayable or specialty coatings extend the operating life, replacement as well as maintenance costs of equipment and structures in areas with vibration, impact, bending, flexing, and thermal cycling. This type of coating is available with superior tensile, elongation, and tear strength properties.


• Rubber Coated Rollers: Rubber coating is also applied on rollers. Rubber coated rollers are used in printing , textile, wood pocessing, paper and pulp industry, plastic foil production, long-distance belt conveying etc


• Rubber Coated Fabrics: Rubber coated fabrics are widely used in textile industry. The properties of the rubber are added to the performance characteristics of the fabric. They are also known as rubber coated textiles, proofed fabrics, proofed textiles or technical coated textiles. The rubber coating on fabrics provides specific performance attributes required for the operating environment e.g. flame retardancy, fuel resistance.
