Rubber coating is one of the most widely used
processes of coating in various applications. Such protective coating is
applied onto or impregnated into a substrate or an object for protective,
decorative or functional purposes. Rubber coating medium 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.
Rubber as a Coating Material- Liquid, Natural, Synthetic Rubber Coating
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.
Natural and synthetic rubber coating both are done in various applications.
However, synthetic rubber coating is more prevalent than natural coating. As
natural rubber can not be used directly for coating purpose, most of the
time latex concentrate that contains roughly 60% rubber are used for the
purpose.
Due to their versatile nature, synthetic rubber coatings, mostly made of
liquid rubber, can be easily sprayed onto any surface for long term sealing,
insulation and protection against moisture, dust and other air borne
materials preventing leakages etc. Liquid rubbers are widely used to create
protective coatings on various materials as well as in caulking and
weatherproofing.
Rubber Coating Selection
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.
How to Apply Rubber Coating ?
Rubber Coating Buying tips When selecting appropriate rubber
coating, the following factors should be considered:
- Temperature
- Friction
- Material being coated
|
Rubber coating is applied to seal tools, flooring, and various
other surfaces. The rubber coating is liquified having consistency of glue.
Applying rubber coating to surfaces needs to be done evenly and quickly so
that all the sides of the surface might dry at the same time. This prevents
formation of bubbles of wet rubber coating. There are a few methods of
applying rubber coating to surfaces, main of which are applying rubber
coating by dipping and by paint brush.

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 coating is widely applied
accross industries and even in homes. Rubber coated fabrics and roofs are
the best examples of applications of rubber coating in homes. Rubber spray
coating and rubber coated rollers can be taken as examples of industrial
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 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 in form of rubber spray coating. Sprayable urethane is
produced to protect all surfaces and equipment which are exposed to any kind
of abrasive and corrosive environments. These spray rubber coatings are easy
to repair and they form and add reinforcement to other highly durable
protective linings. Spray rubber coating 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.
Popular Rubber Coatings
Rubber coating manufacturers always try to
bring in unique and more usful protective coatings to the market. Some of
these products have more advanced features that make them more beneficial to
apply. These popular rubber coatings can be found almost with all the rubber
coating suppliers. Some of such rubber coatings include the following:
- Plasti dip
- Loctite Rubber Coating
- Blue Magic Rubber Coating
- Gardner-Gibson Rubber Coating
