MT-85B one-component primer is a one-component polyurethane primer. MT-85B one-component primer cures by reacting in moist air to form a tough coating with corrosion and wear resistance. MT-85B one-component primer can thoroughly penetrate porous and water-permeable surfaces and has high adhesion to concrete surfaces. MT-85B one-component primer is one of the ideal primers for polyurea and polyurethane elastomer coatings.

All surfaces must be clean and dry.
All previous paints, coatings or lacquers on the substrate must be completely removed unless they are strong and tightly adhered.
Supply form: MT-85B one-component primer is a one-component paint, packed in 200-liter barrels, 200 kg per barrel.
Smaller packages (20 liter and 50 liter packages) can also be configured as needed.
From the time of transportation, the storage period is 6 months, and the storage conditions are: storage in a ventilated room at 5-35℃.
Before use, do not open the lid. Open the lid and use it.
MT-85B single-component primer should be applied by brush or roller. It can also be applied by single-component spraying.
For mortar base surface, it is generally necessary to apply one coat of MT-85B single-component primer at a coating rate of 0.2-0.25kg/square meter, and then proceed with subsequent construction.
MT-85B single-component primer should be topcoated within 12-48 hours after construction. If the topcoat construction cannot be completed within 48 hours, it is recommended to re-apply MT-85B single-component primer.
After painting, it should not rain within 24 hours. If it rains, it is necessary to check the curing of the coating film and re-apply the primer if necessary.
MT-85B one-component primer is susceptible to moisture and must be protected from moisture contamination. Keep sealed. Containers must be sealed with a volatile gas to prevent contamination. After opening, if all components have not been used up, fill with nitrogen or dry gas and seal with wax.
MT-85B one-component primer in the can is flammable. Use only in well-ventilated areas. Avoid heat, fire, flames and fireworks. Use explosion-proof construction equipment. Avoid prolonged or repeated inhalation of vapors or sprays. Applicators should wear approved gas masks. Avoid contact with eyes and skin.
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.
