Wonders of surface coatings by speciality polymers

Surface coatings by polymers can do wonders as they change the surface properties of the substrate such as metal, glass, wood, plastic etc. to that of the Polymers or combination of the polymers with which they are coated. At the same time user can have advantage of the material of substrate such as LOW COST, EASE OF FORMATION AND STRENGTH ETC.

Initially the surfaces were coated to give aesthetically good look and weather resistance to the components. But now the surfaces are coated for specific requirements i.e. to change or modify the surface properties of the components such as

 To impart NON STICK Properties

 To lower water absorption and vapour permeability.

 To alter electrical properties and dielectric Strength.

 To improve resistance to

                 a) Abrasion      
                 b) Radiation     
                 c) High Temperature

 To extend application life.

 To improve mechanical strength, elasticity and surface hardness.

 To alter thermal conductivity.

 To save surface from Fouling

 To increase lubricity

 To reduce system cost.

For some components the surface coatings are so important that the parts and machine can not work without the coating. The spoiled coating of a small component or part can render the entire machine useless e.g. Fuser Rollers of office equipments. If the coating of the office equipment is spoiled the equipments such as copier and printers stop working.
