Application

The application fields of outdoor powder coating

Outdoor powder coatings protect metal substrates exposed to sun, rain, and pollution. Applications: architectural aluminum (windows, doors, curtain walls), outdoor furniture, highway barriers, solar racking, charging stations, telecom cabinets, and agricultural machinery.

Superdurable coatings meet Qualicoat, AAMA 2604/2605, or GSB standards, offering 10+ years of gloss retention and low chalking. PVDF fluoropolymer coatings provide top weatherability for landmarks and coastal sites.

Functional types:

Self-cleaning – uses hydrophilic/hydrophobic nano-technology for rain-washable dirt removal.
High salt-spray resistance – >1000h NSS, meets ISO 12944 C5-H/CX.
Chipping-resistant – high impact strength for barriers and machinery.
Heat-reflective (cool pigments) – lowers surface temperature by 15–20°C.
Anti-graffiti – low surface energy for easy marker/spray paint removal.
Antistatic – surface resistivity 10^6-10^9 Ω for flammable environments.
Available in many colors, gloss levels, textures (sand, wrinkle, hammer), with zero VOCs and reclaimable overspray. Combined with proper pretreatment, outdoor powder coatings deliver durable, corrosion-resistant, and attractive finishes for any exterior metal part.

FAQ

Reasons for pricing differentiation of thermosetting powder coatings

First of all, powder coatings are fixed products, and many factors will affect the pricing of thermosetting powder coatings

Reason 1: The difference of different raw materials, such as the grade quality of resin and curing agent, will affect the level of pricing.

Reason 2: the type of powder, different types of powder coating pricing is not the same, and the color, finish, luster of the powder to price.

Reason 3: The difference of spraying effect, powder rate and spraying area will also affect the pricing of powder.
