Dicyandiamide Cured Epoxy Powder Coating

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.

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.
