High Transfer Efficiency (HTE) Powder

Surface Finish Options Overview

With exceptional adhesion and strength, MT HTE powder coatings are engineered to electrostatically wrap around and penetrate deep recesses and angles of intricately shaped parts, achieving first-pass efficiency rates of up to 85% or higher.

Compared to standard powder coatings, these next-generation polyester-based formulations reduce per-item powder consumption by 20-25%, enhance finish quality, improve line speed, and minimize downtime required for cleaning, resulting in impressive first-pass build rates.

Developed with an exclusive cross-link polymer, STD provides uniform coverage on complex metal parts and assemblies such as refrigerator racks, shelving, patio tables, architectural components, and other finished goods.

A standout in the coatings industry, STD powder coatings are available in both durable and ultra-durable polyester formulations and are suitable for cold-rolled steel, hot-rolled steel, aluminum, and iron substrates.

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.
