Tetrahydroxy Ethane Epoxy Powder Coating (Phenolic Type)

Surface Finish Options Overview

Product Overview

Tetrahydroxy Ethane Epoxy Powder Coating Phenolic Type is a high-performance thermoset coating system designed for applications where you require superior chemical resistance, high crosslink density, and strong thermal stability. Based on phenolic-type epoxy resin chemistry, this coating forms a tightly crosslinked network after curing, delivering excellent barrier protection and mechanical strength.

When you select Tetrahydroxy Ethane Epoxy Powder Coating Phenolic Type, you obtain a durable protective layer suitable for demanding indoor industrial environments. It is particularly appropriate for metal components exposed to aggressive chemicals, elevated service temperatures, and corrosive conditions where long-term structural integrity is essential.

Application

You can apply Tetrahydroxy Ethane Epoxy Powder Coating Phenolic Type in environments requiring enhanced chemical and thermal performance:

• Industrial processing equipment – Reactor frames, tanks, and structural supports

• Pipes and valves – Components exposed to chemicals, oils, and process fluids

• Electrical enclosures – Cabinets operating in industrial plants with chemical exposure

• Heavy machinery components – Metal housings and brackets subjected to mechanical stress

• Energy and utility equipment – Indoor structural metal parts requiring corrosion resistance

Performance verification can be conducted according to internationally recognized standards such as ISO 9227 for corrosion resistance, ISO 2409 for adhesion, ISO 6272 for impact resistance, and ASTM D1308 for chemical resistance evaluation.

Parameters

Note: Final coating performance depends on substrate pretreatment, curing accuracy, environmental conditions, and film thickness.

Features

• High Crosslink Density
  The phenolic-type epoxy structure provides a tightly bonded network, enhancing chemical and thermal resistance.

• Excellent Chemical Durability
  You achieve strong resistance to aggressive solvents, oils, and industrial fluids.

• Reliable Corrosion Protection
  The cured coating forms a dense barrier that protects steel substrates in corrosive indoor environments.

• Mechanical Strength and Stability
  The coating withstands impact and mechanical handling when properly applied and cured.

• Consistent Industrial Finish
  Available in smooth, matte, and textured surface effects to meet functional and operational requirements.

Case

In an industrial chemical processing facility, you required a coating system for valve bodies and equipment supports exposed to cleaning solvents and elevated ambient temperatures. Previous standard epoxy coatings showed gradual surface degradation under repeated chemical exposure.

After implementing Tetrahydroxy Ethane Epoxy Powder Coating Phenolic Type at an average film thickness of 100 μm over pretreated steel substrates, adhesion and corrosion resistance were verified in accordance with ISO 2409 and ISO 9227. Internal chemical resistance checks aligned with ASTM D1308 confirmed improved performance. The coated components demonstrated stable surface integrity and reduced maintenance frequency during routine operation.

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.
