Frequently Asked Questions
Corrosion or degradation involves a deterioration of metals when exposed to an environment resulting in the loss of that metals, the most common cause being the corrosion of metals and steel by water. To protect the metal from corrosion, Metal required a protection layer that stops the deterioration of metals. Hence coating /paint on steel or any other metal substrate gives a layer of protection to stop the corrosion
Usually, there are 2 or 3 types of coat systems used by industries. primer, intermediate and topcoat or primer and topcoat.
Primers: high pigmented coatings that apply to metal surfaces, prior to the application of intermediate coats or topcoats.
The main function of primers is to achieve adequate adhesion to the substrate and to provide intermediate coat adhesion for subsequent coats.
intermediate: With high filler and excellent leveling properties, the intermediate coat prepares the primed substrate for the further application of a topcoat.
It not only contributes to the final appearance but also improves the mechanical properties of the paint system as a whole, especially its resistance to chipping. It also provides an additional barrier against moisture and oxygen thereby further inhibiting corrosion.
Topcoats: final coats for use over primers and intermediate coats. They are formulated to provide good adherence to the undercoat or intermediate coat, the desired appearance (color, gloss, finish) to the painted object, additional protection from the exterior weather, and aid in other protective performance requirements.
Usually sprayed on top of a Primer or Intermediate coat, a topcoat is a glossy, semi-glossy, satin, or matt coating that forms the final interface with the environment. For this reason, the clear coat must be durable enough to resist abrasion and corrosion and stable enough to withstand the combination of UV as well as chemical condensation area.
Recommended product selection criteria :
- Substrates to be painted/coated.
- Purpose of use – Decorative or protection.
- Location – interior or exterior.
- The base of the product – Solvent or Water-based.
- Back Bone of product – Epoxy / PU / Acrylic / Alkyd /Resin.
- Finish – Matt / Glossy / Semi-Glossy/ Satin /Textured, etc.
Epoxy coatings are often used in industrial and automotive applications since they are durable, anti-corrosive, and more effective for heat resistance than latex-based and alkyd-based paints. Epoxy paints are extremely protective in high hummerite, Chemical explosive, Seaboard, and the harshest environment, It also tends to deteriorate, known as “chalking out”, due to UV exposure.
There are various standards available for paint application and testing. Some are below.
SSPC, NACE, AMPP, ASTM, SA, ISO 12944, ECISS (Coatings for steel tubes & Internal liquid epoxy lining), IS 2932, IS 14428, AWWA, and OSHA.
There are major causes of paint failure are paint application defects, several types of defects occurred due to inappropriate paint application, for detail please see the video available on the below link for a better understanding of the causes.
Generally, the cause is moisture contained on the surface during paint application, However, it can also be caused by inadequate surface preparation, using low-quality paint, painting in direct sunlight, and dust or fume exposure location.
Epoxy / PU / Synthetic Enamel / QD/ Wood Enamel / Heat Resistance / Stoving / Lacquers / Anticorrosive / Specialty Coatings / Thinners / Bituminous Coatings/ Floor Coatings/ Construction Solution.
Even minor rust adhering to the surface will spoil the paint in the long run as rust will propagate through the paint. Hence it is always advisable to make proper surface preparation before painting/coating a substrate/surface. Loose rust particles must remove by wire brush/sandpaper and rust adhering / cleaning to the surface are removed by use of surface treatment products. Post required wiped clean to carry primer & topcoat application.
Matte Finish: Matte finish provides a smooth and clear look.
Satin Finish: Satin finish paints are the slightly shinier counterparts of Matte finish paints.
Semi-Gloss: Semi-gloss paint finishes are known for both their durability and flexibility. This finish is more reflective than satin and less glossy than high gloss.
High Gloss: They are the epitome of providing a good amount of durability and aesthetic product look.

The most important benefit is the tremendous saving in hours of maintenance work and cost, Two factors affect this time saving:
- High-quality paint generally covers better than less expensive paints – so less is needed. And less time is needed to apply it.
- High-quality paint can provide extensive life to your product, in some cases, no frequent maintenance is required which benefits the customer to save extra cost, and time and saving structure, Installation, or Machine from replacement.
