Dicyandiamide Cured Epoxy Powder Coating

Surface Finish Options Overview

Product Overview

Dicyandiamide Cured Epoxy Powder Coating is a thermoset coating system designed to provide you with reliable corrosion resistance, strong adhesion, and stable mechanical performance for indoor metal components. Using dicyandiamide as a curing agent, this epoxy system forms a dense crosslinked network during baking, resulting in a hard, chemically resistant protective film.

When you select Dicyandiamide Cured Epoxy Powder Coating, you gain a cost-effective and technically proven solution for industrial equipment, electrical enclosures, and fabricated metal parts operating in controlled environments. It is particularly suitable for applications where durability, chemical resistance, and long-term substrate protection are essential, while continuous UV exposure is limited.

Application

You can apply Dicyandiamide Cured Epoxy Powder Coating across multiple industrial sectors:

• Industrial equipment – Machine frames, housings, brackets, and protective covers

• Electrical cabinets and enclosures – Control panels, distribution boxes, and switch cabinets

• Pipes and valves – Indoor fluid handling components requiring corrosion protection

• Home appliances and electronics – Internal metal frames and structural parts

• Construction metal components – Indoor railings, supports, and fabricated steel parts

• OEM production lines – Batch or continuous coating systems requiring consistent curing behavior

Performance testing can be conducted in accordance with internationally recognized standards such as ISO 9227 for corrosion resistance, ISO 2409 for adhesion, ISO 6272 for impact resistance, and ASTM D3363 for hardness evaluation.

Parameters

Note: Final coating performance depends on substrate preparation, curing control, environmental exposure, and film thickness.

Features

• Proven Curing Technology
  Dicyandiamide curing provides stable crosslinking and consistent film performance in standard industrial baking conditions.

• Strong Corrosion Protection
  You obtain a compact epoxy barrier that protects steel substrates in humid indoor environments.

• Excellent Adhesion
  With appropriate pretreatment such as phosphating or chromate-free conversion, the coating bonds securely to metal surfaces.

• Mechanical Strength and Hardness
  The cured film resists impact and surface wear, making it suitable for equipment subjected to handling and assembly.

• Cost-Effective Industrial Solution
  This system offers reliable indoor protection with balanced performance and controlled production costs.

Case

In an industrial equipment manufacturing facility, you required a durable coating for electrical cabinets and machine housings installed inside a production workshop. The environment involved occasional oil mist and mechanical handling during installation and maintenance.

After applying Dicyandiamide Cured Epoxy Powder Coating at an average film thickness of approximately 80–100 μm over properly pretreated steel substrates, adhesion and corrosion resistance were verified according to ISO 2409 and ISO 9227. The coated components maintained structural protection and surface integrity during regular plant operation, supporting long-term equipment reliability.

Types of powder coating

Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).

Powder coating colours and effects

Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.

Powder coating process

The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.

Powder coating benefits

Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.

Applications for Powder Coatings

Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.

FAQ

What is Powder Coating?

Powder coating is a dry finishing technology where finely ground powder is electrostatically sprayed onto a metal or non-metal surface and then cured at high temperature. After curing, the powder melts into a continuous, durable, and decorative coating layer.

What does powder coating do?

Powder coating protects the substrate from corrosion, weathering, chemical attack, and mechanical wear. It also provides decorative appearance with rich colors, gloss levels, textures, and special effects.

Is powder coating better than paint?

In many industrial applications, powder coating outperforms liquid paint. It forms a thicker and tougher coating, resists corrosion and chemicals better, and does not contain VOCs. It also provides excellent consistency and cost-effective mass production.

Why is it called powder coating?

It is called powder coating because the coating material is a solid powder instead of a liquid paint. The coating is formed by melting and curing powder particles under heat.

What are the different types of powder coating?

Powder coatings include several families depending on resin chemistry:

• Epoxy powders

• Polyester powders

• Epoxy-polyester hybrid powders

• Polyurethane powders

• Acrylic powders

• Fluorocarbon (PVDF) powders

Each type has its own performance features such as corrosion resistance, UV resistance, chemical resistance, outdoor durability, or decorative properties.

Which material is used in powder coating?

Powder coatings are based on thermoset or thermoplastic resins combined with pigments, curing agents, fillers, additives, and in some cases metallic or effect particles. Common substrates include steel, aluminum, galvanized metal, MDF, and certain heat-resistant plastics.

How long will powder coating last?

The lifespan depends on powder type, film thickness, application method, pretreatment, and service environment. Indoor coatings can last more than 10–20 years. High-grade outdoor polyester or fluorocarbon powders can last 15–25 years or longer under UV exposure.
