The differences between powder coating and fluorocarbon coating for door and window profiles

2025-09-01
Many people aren’t familiar with either powder coating or fluorocarbon coating—so today, the editor will provide a detailed explanation of the differences between the two.
Powder Coating
The raw materials for powder coating are:
Polyurethane, polyurea resin, epoxy resin, hydroxyl polyester resin, and epoxy-polyester resin can be formulated into a wide variety of colors.
Characteristics of powder coating:
The spraying equipment includes manual models as well as automatic suspension systems, offering easy operation. It delivers a coating thickness of 30 microns or more, with excellent resistance to impact, abrasion, corrosion, and weathering—plus, the paint used is more affordable than fluorocarbon coatings.
The biggest weakness of powder coating:
Concerned about UV exposure from the sun—long-term irradiation can lead to natural fading—color differences between the sun-facing and non-sun-facing sides of window and door profiles become noticeably apparent after just a few years, typically within 2 to 5 years. Today, the market offers colored aluminum profiles that are produced using powder coating, significantly expanding the variety of available colors while also enhancing the material's resistance to corrosion.
Fluorocarbon Coating
Fluorocarbon coating is a high-end, premium-grade spray finish that comes with a higher price tag—but it has long been widely used abroad. In China, it has only begun to be extensively applied to aluminum panel curtain walls and window/door materials in recent years. Thanks to its exceptional qualities, it’s increasingly gaining attention and popularity among both the construction industry and end-users.
Characteristics of fluorocarbon coating:
It boasts exceptional resistance to fading, frosting, atmospheric pollution (such as acid rain), and corrosion, along with strong UV protection, excellent crack resistance, and the ability to withstand harsh weather conditions—features that far surpass those of conventional coatings.
Fluorocarbon spray coatings are formulated using polyvinylidene fluoride resin, represented as [nCH2CF2]n (PVDF), as the base material—or alternatively, with metallic aluminum powder added as a pigment. The chemical structure of the fluorocarbon base features strong carbon-fluorine bonds, which are inherently short and highly stable, forming one of the most robust and durable chemical linkages known. This exceptional stability at the molecular level gives fluorocarbon coatings unique physical properties that set them apart from conventional paints. Beyond their outstanding mechanical durability, including superior abrasion resistance and impact strength, these coatings truly excel in harsh climatic conditions and environments, delivering long-lasting color retention and unparalleled resistance to UV degradation.
Fluorocarbon coating manufacturers have seen their warranties on coating lifespan evolve—from an initial 10 years and 15 years, now extending to guarantees of up to 20 years.
U.S. research institutions conducted comparative tests on fluorocarbon coatings, super coatings, and conventional paints. Samples coated with each type were exposed for 12 years—first under the scorching sunlight of Florida, USA, and then in a harsh, humid, salt-laden environment. The results clearly demonstrated that fluorocarbon coatings exhibited 30% and 80% greater stability and durability, respectively, compared to the other two types of coatings, ensuring their reliability even in the most challenging conditions.
