Pure polyester powder coating developed for exterior metal products where weathering, color retention, and corrosion-system durability matter. The exact durability grade, finish, pretreatment, film build, and cure profile are selected and validated for the project.

DAMEI outdoor pure polyester powder coating is developed for metal products exposed to sunlight, rain, temperature changes, and industrial handling. Typical applications include architectural metalwork, aluminum profiles, outdoor furniture, agricultural equipment, guardrails, enclosures, gates, and fabricated steel components.
Outdoor durability is a property of the complete coating system, not the resin name alone. The correct grade must be chosen for the climate, exposure class, substrate, pretreatment, film thickness, color, gloss, and required test method. No fixed service-life claim should be applied before those conditions are known.
Surface preparation is decisive. The metal should be clean and dry with a pretreatment suitable for the substrate and exposure class. During the trial, measure actual part temperature, coating thickness, adhesion, color, gloss, and coverage at edges and recesses. If corrosion performance is critical, validate the whole pretreatment-plus-powder system on representative parts rather than relying on a generic powder claim.
Weathering data must be interpreted against the exact formulation, color, gloss, film thickness, and test standard. Accelerated laboratory tests help compare systems but do not translate directly into a guaranteed number of outdoor years.
For the selected formulation, request the available technical data sheet, safety data sheet, approved color panel, sample test record, and batch documentation. If a regulation or customer standard is mandatory, name the exact document and acceptance criterion before ordering so applicability can be checked.
DAMEI's published ISO management-system certificates can be reviewed on the About page. They describe the certified management scope and should not be represented as product-specific weathering or compliance certificates.

There is no responsible universal answer. Service life depends on formulation grade, color, pretreatment, film build, climate, part design, installation, and maintenance. Define the exposure and test requirement first.
Polyester systems are normally the starting point for UV-exposed applications. The exact grade still needs validation for the project.
A match can be developed, but the team needs to know whether the target is the original color or the aged surface. A retained original panel is preferable when available.
No. Substrate preparation, pretreatment, edge design, film thickness, cure, and damage control are all part of corrosion performance.
Include the substrate, exposure, color reference, finish, test requirements, line conditions, expected usage, and destination market.

Hybrid epoxy-polyester powder coating for indoor metal products that need a smooth finish, reliable adhesion, and a practical balance of appearance and mechanical performance. Color, gloss, texture, cure window, and line settings are confirmed through samples and production trials.
Decorative metallic and special-effect powder coatings for metal products that require controlled color, sparkle, texture, or visual depth. Samples and line trials establish the approved appearance because equipment, reclaim, film build, and viewing angle can change the result.
Powder coating systems for external valve and pipe surfaces, developed around the substrate, pretreatment, service environment, geometry, and required corrosion tests. Potable-water, internal-contact, or regulated applications require separate documented approval for the exact formulation and end use.
