There is a wide assortment of materials that are used in the processing and manufacturing industry. When the various products have been created, they will require protective coating so as to ensure their finish stays intact and does not acquire undue superficial damage. This is where protective coatings come in. Typically, protective coatings will be referred to according to the resin used in creating them. Some of the most popular resins include alkyd, acrylic, epoxy, and polyurethane. It should be noted that two similar resins that come from two different manufacturers would have varying properties. This is because the other components used, such as additives, pigments, solvents and more will create differences in the serviceability of the protective coating. The following are some of the features to look for in protective coatings.
Chemical resistance of the protective coating
This feature refers to the coating's capability to resist breaking down when exposed to chemicals. These coatings are suited for surfaces or items that are exposed to chemicals on a constant basis.
Water resistance of the protective coating
Most materials will have their surface compromised when exposed to copious amounts of water for an extended period of time. Water resistant coating function to ensure that this exposure to moisture does not compromise the structural integrity of the surface. Water resistance is especially prudent when trying to protect the material from premature corroding.
Ease of adhesion of the protective coating
Another feature to establish when in search of a protective coating is how easily the coating will adhere onto the substrate of the material. Typically, the adhesion rate of the coating will depend on both chemical as well as physical interactions between the material and the protective coating. It should be noted that the poorer the adhesion, the poorer the performance of the coating. Therefore, only seek put protective coating that will easily and completely adhere to the substrate.
The cohesive strength of the protective coating
The protective coating that you choose should have high cohesive strength. His mean it should be capable of withstanding the temperature changes as well as stresses of the curing process without it becoming adversely affected.
Abrasion resistance of the protective coating
If you would like to ensure that the surface of the material will not be prone to superficial scratches and chips, then you should consider protective coatings with high abrasive resistance. These types of coatings will be best suited to items that will be exposed to high impact.
