What is the best paint for aluminum veneer surface treatment

Aluminum veneer can use fluorocarbon paint.

The spraying process is the best.

There are three commonly used forms of exterior surface coating for aluminum veneer curtain walls, namely powder, polyester, and fluorocarbon. Each of these three coatings has its own uses, such as indoor ceilings.

Powder or polyester is used for suspended ceilings, while fluorocarbon paint is commonly used for aluminum veneer for outdoor curtain walls.

No matter how harsh the climate of fluorocarbon paint is, such as high temperature exposure, high air humidity, and acid rain.

Heavy storms and rains. It's all as good as new. The outdoor climate is unpredictable, and in order to last for more than a decade, it is wise to use fluorocarbon paint.

If you are greedy for cheap choice of polyester paint, ** is cheaper, but the service life is not as long as fluorocarbon paint, comprehensive consideration may not be as cost-effective as fluorocarbon paint, after all, fluorocarbon aluminum veneer ** is only more than 20 yuan per square meter more expensive than polyester aluminum veneer.

Therefore, aluminum veneer must be selected according to the anti-corrosion needs when making paint, Yasheng paint recommends the use of fluorocarbon paint, which is also the most used one at present, and the performance is also good.

Special color card for aluminum plate spraying - RAL K7

The surface of the aluminum veneer has undergone pre-treatment such as chromization, and fluorocarbon spraying is generally used outdoors, and polyester coating and powder coating can be selected indoors.

Polyvinylidene fluoride (kanar500) of fluorocarbon coating topcoat and varnish is generally divided into two, three or four coats, fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid and alkali, rain salt, fog and various air pollutants, excellent cold and heat resistance, can resist strong ultraviolet radiation, long-term discoloration, no chalking, long service life.

Aluminum veneer can use fluorocarbon paint roller coating process is the best.

Fluorocarbon aluminum veneer is a curtain wall surface that is generally pretreated by chromization and then treated with fluorocarbon spraying. Fluorocarbon aluminum veneer is a polyvinylidene fluoride resin for fluorocarbon coatings, topcoats and varnishes.

The main benefits are as follows:

1. Light weight, good rigidity, high strength, thick aluminum plate weighs 8kg per square plate, and tensile strength is 100-280N mm2

2. Good durability and corrosion resistance. PVDF fluorocarbon paint based on Kynar-500 and Hylur500 can be used for 25 years. Aluminum veneer curtain wall building.

3. Good manufacturability. Using the process of processing first and then painting, the aluminum plate can be processed into a variety of complex geometries such as plane, arc and spherical surface.

4. Uniform coating and diverse colors. The advanced electrostatic spraying technology makes the adhesion between the paint and the aluminum plate uniform, the color is diverse, and the choice space is large.

5. It is not easy to stain and easy to clean and maintain. The non-adhesive nature of the fluorine coating film makes it difficult for contaminants to adhere to the surface and has good cleanability.

6. Convenient and fast installation and construction. The aluminum plate is formed in the factory, and it can be fixed on the skeleton without cutting at the construction site.

7. It can be reused, which is conducive to environmental protection. Aluminum plate can be 100%**, different from glass, stone, ceramics, aluminum-plastic panels and other decorative materials, ** high residual value.

Fluorocarbon spray paint is the best, but the cost is high, and the surface treatment requirements are also high, such as not being able to use hexavalent chromium treatment.

The surface of the aluminum can be oxidized in the air without painting, and the aluminum will be oxidized in the air to form a protective film without further oxidation.

Aluminum veneer. The thickness of the paint film varies depending on the type of spray paint.

Such as: powder coating.

80 150 m, fluorocarbon spraying.

35 60 m, polyester paint spraying: 20 35 m, roller paint: 20 25 m, wood grain transfer: 60 80 m, porcelain: 25 40 m, laminating polymer: 80 220 m.

Dry the aluminum plate after washing.

40-60 m is generally qualified. My side is an aluminum veneer manufacturer.

What paint is used for aluminum plate painting.

Hello! Dear, I'm glad to answer for you! Hello, aluminum plate painting can be done with fluorocarbon paint and polyester paint, but before painting, the aluminum plate oil and rust stains must be removed to ensure its adhesion and protection.

It refers to coatings with fluorine resin as the main film-forming substance; It is also known as fluorocarbon paint, fluorine coating, fluorine resin coating, etc. Among all kinds of coatings, fluororesin coatings have particularly superior properties due to the large electronegativity of fluorine elements introduced and strong carbon-fluorine bond energy. It is resistant to weathering, heat, low temperatures, and chemicals, and has unique non-stick and low-friction properties.

After decades of rapid development, fluorine coatings have been widely used in various fields such as construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, and household goods. It has become a coating brand with the highest comprehensive performance after high-performance coatings such as acrylic coatings, polyurethane coatings, and silicone coatings. At present, there are three main types of fluororesin coatings that are widely used: PTFE, PVDF, and PEVE.

The earliest "fluorocarbon coatings" were actually born as early as 1938, which is the well-known Teflon coating of DuPont, that is, polytetrafluoroethylene (PTFE), polyperfluoropropylene (FEP) and other copolymers. This kind of material is known as "corrosion-resistant, never stick Teflon" due to its unique and excellent heat resistance (180-260), low temperature resistance (-200), self-lubrication and chemical stability, etc., fluorocarbon paint is generally divided into trifluorine and tetrafluorine, and tetrafluorine has higher anti-corrosion performance. Due to the extremely high liquefaction temperature required for use, the dispersion of pigments is very poor, so it has been used only in non-stick pans, medical treatment, aviation and other fields, and has not entered the construction field.

<> "Aluminum plate is a more commonly used material, so before painting it, you still have to understand it clearly.

1. What kind of paint is used for aluminum plate painting

You can use fluorocarbon paint and polyester paint, but you must remove the aluminum plate oil and rust stains before spraying the paint scale, so as to ensure its adhesion and protection. Ordinary paint is more difficult to attach to the surface of the aluminum plate, and it is easy to fall off the paint, so there is no way to achieve the effect of anti-corrosion decoration.

Second, what aspects need to be paid attention to in the construction of aluminum plate painting

1. Before painting, the surface of the aluminum plate should be cleaned first, especially with oil, it should be wiped clean before it can be dismantled, which is also to improve the adhesion of the primer, do not blast or do a grinding treatment on the aluminum plate, and the treatment is relatively simple.

2. When spraying paint on the surface of the aluminum plate, the correct epoxy primer and curing agent should be adjusted together, and then the appropriate residual epoxy diluent should be added, and it must be stirred evenly to spray these mixtures on the surface of the board, about two to three times, until the paint film reaches the thickness.

3. When the primer on the surface of the aluminum plate is dry, before spraying the topcoat, it is also necessary to prepare the fluorocarbon paint and the curing agent according to the proportion, and then add the appropriate fluorocarbon paint thinner to it, and then stir it evenly, spray it on the surface of the aluminum plate about two to three times, until the thickness is reached, after the painting is completed, it is necessary to determine whether the paint film is intact, and when the paint layer is completely dry, the aluminum plate can be used normally.

Spraying aluminum plate is to spray various colors of fluorocarbon paint (or polyester paint) on the surface of the aluminum plate, which is baked and cured at high temperature, also known as baked aluminum plate. It can be used for exterior and interior wall decoration of buildings, indoor ceilings and so on.

Sprayed aluminum alloy profiles have excellent corrosion resistance and weather resistance, strong and durable, beautiful appearance and decoration, simple production process than anodizing, environmental protection, etc., and have been widely used in construction, decoration, transportation and other industries.

Aluminum alloy profiles must be chemically cleaned and corroded in the pre-spraying treatment to remove contaminants such as adhesion, natural oxide film and dust on the grease surface, so that the aluminum alloy substrate is exposed and a uniform activation surface is formed, which is the key to ensure the quality of chromate conversion film and spraying quality.

Spraying of aluminum sheets usually goes through three coatings and two baking: spraying aluminum sheets with three coatings and two baking fingers: opening three sets of spray guns when spraying, the first primer, the second color coat (fluorine or polyester paint), the third coating protective topcoat (varnish), two baking means that the aluminum plate goes through three coats and then two bakes.

But now the spraying line is basically: three layers of one baking, two coatings and one baking.
