EPOXY COATINGS
Epoxy coatings are manufactured via a chemical reaction of an epoxide resin and a polymine hardener.

Epoxy coatings offer excellent resistance to abrasion, turbulence, toxic chemicals, and extreme temperatures.

Epoxy coatings last for a longer time and also resist deteriorating materials. Epoxy coatings are famous for diverse uses on steel, aluminium, concrete, etc.

FAQs
What are the applications of epoxy?

Epoxy has a wide range of applications due to its strong adhesion, chemical resistance, and durability. It’s commonly used in coatings for floors and machinery, adhesives in construction and manufacturing, composites for automotive and aerospace industries, electrical systems for insulation, and art for resin casting. Epoxy’s versatility makes it valuable in diverse sectors.

What are epoxy coatings used for?

Epoxy coatings are used for their durability and resistance to wear, chemicals, and water. Commonly applied on concrete floors in commercial and industrial settings, they provide a hard, protective surface. They’re also used in automotive, marine, and aerospace industries for corrosion resistance, and in electronics for insulation and protection.

Where do you apply the epoxy coating?

Epoxy coatings are typically applied to concrete floors in garages, warehouses, and industrial buildings due to their durability and resistance to heavy traffic and chemicals. They’re also used on metal surfaces in automotive and marine applications for corrosion resistance, and in electronic devices for insulation and protection against moisture and dust.

What is the best way to apply epoxy?
The best way to apply epoxy is by first preparing the surface thoroughly, ensuring it’s clean, dry, and free of debris. Mix the epoxy resin and hardener according to the manufacturer’s instructions. Apply it evenly with a brush, roller, or sprayer, and ensure a well-ventilated area for proper curing. Follow specific product guidelines for optimal results.
How many coats of epoxy?
The number of epoxy coats required typically ranges from one to three, depending on the application’s specific needs and the product’s characteristics. For floor coatings, two coats are often standard to ensure adequate thickness and even coverage. In some cases, a third coat or a topcoat might be necessary for extra durability or a specific finish.
