The Differences Between Fluorocarbon Coating and Powder Coating for Window and Door Profiles
Release date:
2025-09-01
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:
Fearful of UV radiation from the sun—long-term exposure can lead to natural fading—window and door profiles often show a noticeable color difference between their sun-facing and non-sun-facing sides after just a few years, typically within 2 to 5 years. Today, the market offers colored aluminum profiles that are created using powder coating, enhancing both the variety of available colors for windows and doors and significantly boosting their resistance to corrosion. 
Fluorocarbon Coating:
High-end coatings come with a higher price tag but have long been widely used abroad. In China, they’ve only recently begun to be extensively applied to aluminum panel curtain walls and window/door materials. Thanks to their outstanding features, these coatings are 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 is stabilized by strong carbon-fluorine bonds, which are among the shortest and most robust chemical bonds known. This inherent stability at the molecular level gives fluorocarbon coatings unique physical properties that set them apart from conventional paints. In addition to exceptional durability and impact resistance in terms of mechanical performance, these coatings also exhibit outstanding longevity in resisting fading and UV degradation, making them particularly well-suited for harsh climates and environments.
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% higher stability and durability, respectively, compared to the other two types of coatings, ensuring reliable performance even in some of the most challenging conditions.
