Powder Coatings for Agricultural and Construction Machinery MT-601 is an outdoor polyester powder coating series specifically developed for agricultural and construction machinery and related equipment. You can rely on MT-601 to deliver stable appearance, strong adhesion, and reliable corrosion resistance for machinery operating in demanding outdoor and industrial environments.
You can apply MT-601 to a wide range of heavy-duty machinery and structural components exposed to outdoor weathering and mechanical stress, including:
Construction machinery frames and attachments
Logging and forestry machinery components
Agricultural machinery housings and supports
Mining machinery structures
Truck bodies and external metal components
Performance verification is typically conducted on cold-rolled steel panels commonly used in machinery manufacturing. Testing focuses on adhesion, impact resistance, corrosion resistance, humidity resistance, fuel resistance, and artificial weathering in accordance with ISO and ASTM standards.

You achieve excellent leveling, resulting in a smooth and uniform coating appearance.
You benefit from strong adhesion that supports long-term coating stability on steel substrates.
You gain reliable salt spray resistance suitable for outdoor and industrial environments.
You obtain stable aging resistance, helping maintain color and gloss during service life.
You apply a coating system designed for heavy machinery exposed to vibration, impact, and weathering.
We solved a corrosion durability challenge for a construction machinery manufacturer.
The customer required a coating for truck bodies and machinery components that could withstand long-term outdoor exposure, fuel contact, and high humidity. Their previous coating system showed edge corrosion and gloss loss after extended service.
We recommended MT-601 and supported the customer in optimizing curing conditions and film thickness control. After implementation, laboratory evaluations showed improved adhesion, stable salt spray performance, and consistent appearance after artificial weathering and damp heat testing conducted under international standards. This helped the customer reduce coating-related maintenance and improve equipment durability.
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 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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
