All About Protective Coating In Williston

By Mattie Knight


Protective coating is more commonly called industrial coating in most parts of the world because of its properties. As the name suggests, protective coating in Williston ND is mostly used for protective purposes rather than aesthetic properties although it may be used to achieve both tasks. As a result of the properties of the product, its application is very different from other normal coatings.

Mainly, these coatings are used to protect structures made of steel such as bridges, offshore platforms, and underground pipes. Protection is provided against weather elements like sun rays, rainfall, and frost. Protection may also be provided against water from salty or fresh water bodies like in the case of offshore platforms. Today people talk of fire resistant coatings because they do not burn like other coatings that act as fuel to the fire.

Polyurethane, epoxy, and moisture-cure urethane are among the major polymers used in the manufacture of industrial coatings. Besides the three polymers named above, fluoropolymer is also included in some brands. Other substances are also included in the manufacture. Xylan dry-film lubricants for instance contain thermoset polyimide, polyamide binder resins, and fluoropolymers. Fluoropolymers are of different types and the major ones include PFA, FEP and PTFE. Various solvents are used to keep polyamide binders in suspension when they are used. Examples of solvents include xylene, ethyl acetate, dimethlformamide, and N-methyl 2-yrrolidone.

The market today, is filled with industrial coatings of different brands. Xylan, PVD, inorganic zinc, and phosphate coatings are some of the major examples. Basically, there are variations among the various brands that make them different. That is why one should research before making a purchase. Compatibility between the product and the surface must be ensured.

Typically, the coating system is comprised of three items, that is, a top coat, an intermediate coat and a primer. The applied coat functions as protection for the steel on which it is applied against corrosive agents such as soil, water, and the atmosphere. Besides providing that kind of protection, they are also used on garage floors to protect against wearing caused by feet. Examples of products used on garage doors include polyaspartic, polyuria, and epoxy.

There are four main stages involved in the procedure of applying a three coat system. The four stages are abrasive blasting, application of primer layer, intermediate layer, and the final top layer. Abrasive blasting helps in the removal of unwanted surface materials such as dirt, grease, oil, graffiti, mold, and old paint. It also readies the surface for the primer by roughening it.

The primer functions to wet the surface and create a layer over which to apply the intermediate coat. Consequently, the intermediate layer makes the surface impermeable and helps to build the thickness. The final top coat offers aesthetic value and helps in resisting chemical attack.

NACE International and The Society for Protective Coatings (SPC) are the two major professional organizations in this industry. Practitioners are certified by them in addition to regulating industrial practices. For one to become a Protective Coating Specialist, they must master skills in reviewing bidders lists, creating paint maintenance programs, and conducting site surveys. Additionally, they must understand issues concerned with health, environmental, and safety.
