Epoxy Coatings Manufacturers In Kolkata

Epoxy Coating is a durable, protective finish made by mixing two components: a resin and a hardener (also called a curing agent). Once mixed, the chemical reaction creates a hard, plastic-like material with excellent adhesion, chemical resistance, and mechanical properties.

🔹 Key Features of Epoxy Coating

Durability: Highly resistant to wear, abrasion, and impact.

Chemical Resistance: Withstands oils, solvents, acids, and alkalis.

Adhesion: Bonds strongly to concrete, metal, wood, and other surfaces.

Water Resistance: Impermeable to moisture, making it ideal for waterproofing.

Glossy Finish: Offers a high-sheen, professional look (though matte options are available).

Corrosion Protection: Widely used on metal surfaces to prevent rust.

🔹 Common Uses

Industrial floors (factories, warehouses)

Garage floors

Commercial kitchens

Aircraft hangars

Marine applications (boats, ship hulls)

Steel pipelines and tanks

Electronics (as an insulating coating)

🔹 Types of Epoxy Coatings

Solvent-Based Epoxy:

Durable and chemical-resistant

Contains VOCs (requires proper ventilation)

Water-Based Epoxy:

Easier to apply, low VOCs

Slightly less durable than solvent-based

100% Solids Epoxy:

No VOCs, very thick and durable

Often used in industrial settings

🔹 Application Process

Surface Preparation:

Clean and degrease surface

Remove existing coatings, if needed

Ensure the surface is dry and slightly roughened for better adhesion

Mixing Components:

Resin and hardener must be mixed in correct ratios

Pot life (time before it hardens) is usually 30–60 minutes

Application:

Applied using a roller, brush, or sprayer

May require multiple coats

Curing Time:

Touch dry in 6–12 hours

Full cure in 5–7 days (varies by product and temperature)

🔹 Advantages

Long-lasting

Resistant to harsh environments

Aesthetic appeal (custom colors, flakes, textures)

Easy to clean and maintain

🔹 Disadvantages

Sensitive to UV light (can yellow over time unless top-coated)

Requires thorough surface prep

Can be slippery when wet (unless anti-slip additives are used)

Pot life is limited after mixing

🔹 Safety & Environmental Notes

Always use PPE (gloves, mask, goggles) during application

Work in well-ventilated areas if using solvent-based epoxy

Dispose of leftovers and containers according to local regulations
