Uses Of Protective Paints

The protective paints are pigmented liquids or powders which are used to protect and/or beautify surfaces in industrial or home use. They are normally made of a resin, a solvent, and additives pigments and in some cases diluents.

There are two basic types of such protective paints, the solvent based and the water based ones. The solvent based paints contain one or more volatile organic compounds whereas the water based paints contain mostly water but also some chemicals such as ethers and alcohols.

The protective pains are applied by using brushes and rollers but there are also some that are in spray systems. They can be applied o almost any industrial surface such as asphalt, ceramic, concrete and masonry, fabric and fiber, fiberglass, glass, graphic, metal, paper and paperboard, plastic, rubber and elastomer, and wood, and can have different colors from black, blue, brown, gray, green to orange, purple, red, white, and yellow.

When it comes to discussing the use of protective paints, it is important to remember that they vary in terms of chemistry. Hence, there are acrylic protective paints which are suitable for bonding metal, oily surfaces, glass, ferrite, and plastics. The epoxy paints are used almost exclusively in aircraft components and are more resistant to environmental degradation. Polyester and polyurethane protective paints are used in marine applications whereas the polytetrafluoroethylene (PTFE) based ones are suitable for almost universal use as they have a higher thermal stability. The protective paints are available with a variety of other special features such as being anti-static or conductive, heat resistant, fire retardant, or designed to withstand high temperatures, rust preventive, waterproof, water repellant.

Protective paints are used also in aerospace, architectural and construction, automotive, and electronics industries, as well as in marine, medical, military, optical, pharmaceutical, semiconductor, and textile applications.
