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 and can be used on many elastomeric components like seals, o-rings, gaskets, 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 according to the kind of 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

Why rubber is preferred 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

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

Types 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.
  • Easy to apply.
  • Equipment cleans easily with water and cleaning must be done before coating hardens.
  • It provides excellent exterior durability.
  • It also resists ultra violet rays.
  • Rubber roof coating expands and contracts with the roof substrate base.
  • It resists cracking and chipping.
  • It also resists dirt buildup.
  • The high tensile strength resists hail and foot traffic.
  • It has a low toxicity and is non-pollutant.
• Specialty/Sprayable coating
  Specialty coating is the answer for applications that require on-site repair. Huge tanks, launder systems, and equipment with intricate detail work are all good candidates for 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.
