The fluorocarbon color coated aluminum coil has the advantage of long service life compared to the polyester color coated aluminum coil.
Generally, fluorocarbon coated aluminum coils and aluminum sheets have a service life of more than 20 years,
while polyester color coated aluminum coils have a service life of about 10 years.
The fluorocarbon color coated aluminum coil has a long service life, and can maintain a significant chromatic aberration for 20 years.
It is 10 years longer than the polyester color coated aluminum coil.
It is highly resistant to corrosion and is widely used.
Generally used in roofing waves, fireproof veneers, aluminum ceilings, blinds, roller shutters, garage doors, lighting, furniture,
electronics and other different places.
Fluorocarbon color coated aluminum coil a product coated with high-quality fluorocarbon paint on the surface of aluminum foil.
Fluorocarbon paint has better weather resistance and long service life, and is the first choice for outdoor products.
CAMELSTEEL’s fluorocarbon color coated aluminum coil coated with high-quality paints such as Nippon and PPG,
which can better guarantee the service life of color coated aluminum coils.
The history of fluorocarbon coatings is relatively short, but it is growing rapidly. The basic component of the fluorocarbon coating is a fluororesin.
The molecular chain structure of the fluorescein has a C-F bond, and it’s bond energy is 485 KJ/mol.
It is the first among all chemical bonds; it has a spatial shielding effect formed by fluorine atoms, so it has excellent chemical stability,
heat resistance, acid and alkali resistance, flame retardant/fire resistance, aging resistance, and self-lubricity.
Mainly used in household appliances is polytetrafluoroethylene (PTFE), which can be used continuously for a long time below 260 ° C.
It does not dissolve or swell in any known solvent, even at high temperatures, oil and water do not work for it…
Excellent self-lubricating and hydrophobic oleophobic double-solubility, making the fluorocarbon film very “non-sticky” and easy to clean.
Therefore, it is also frequently used in the field of small household appliances, such as cookware inner walls,
electric iron bottom plates, food trays, cooker panels, and the like.
The fluorocarbon paint-coated aluminum coil is produced by a roll coating process.
The roller coating uniformly applied to the aluminum coil by the friction and pressure drop of the roller,
and the coating particles are horizontally arranged on the surface of the aluminum foil.
The surface of the roll is smooth and smooth, the visual effect is good, and the surface is not easy to collect ash.
Another type of coating method is spraying. Compared with the roll coating, the coating is sprayed on the surface of the aluminum coil through the nozzle,
so that the coating particles are arranged vertically on the surface of the aluminum coil,
which makes the surface of the color coated aluminum coil relatively rough and easy.
The accumulation of dust will greatly reduce the quality of the color coated aluminum coil.
There are some advantages to the roll-coated aluminum coil. For example, the surface color difference is small and soft.
Because of the surface very smooth and very clean, it is not easy to be scratched, although the price relatively high, the price is very high.
Fluorocarbon coated color coated aluminum (PVDF) mainly refers to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and
other small amounts of the fluorine-containing vinyl monomer.
This chemical structural stability and firmness make the physical properties of fluorocarbon coatings different from conventional coatings.
In addition to the abrasion resistance in terms of mechanical properties, impact resistance has excellent performance,
especially in harsh weather and environment, showing long-lasting resistance to fading and UV.
After baking at high temperatures, the coating has a tight molecular structure and is extremely weather-resistant.
Quality requirements for fluorocarbon color coated aluminum coils:
The 60° gloss value of the fluorocarbon coating shall be in accordance with the contract, with an allowable deviation of ±5 gloss units.
Fluorocarbon color coated aluminum coil color and color difference:
the coating color should be basically the same as the standard swatch specified in the contract.
When measured by an instrument, the color difference ΔEab* ≤ 1.5 between the monochromatic coating and
the standard swatch, and the color difference ΔEab* ≤ 1.5 between the same batch of products.
Dry film hardness of fluorocarbon color coated aluminum coil:
The coating tested by pencil scratch and the hardness was ≥1H.
Adhesion of fluorocarbon color coated aluminum coil: The dry, wet and boiling water adhesion of the coating should reach 0.
Impact resistance of fluorocarbon color coated aluminum coil:
The front side of the coating should not crack or fall off after the impact test,
but fine wrinkles allowed in the periphery of the depression.
Abrasion resistance of fluorocarbon color coated aluminum coil: After the falling sand test, the wear coefficient should be ≥1.6 L/μm.
The fluorocarbon color coated aluminum coil is resistant to hydrochloric acid:
after the coating tested by hydrochloric acid,
there should be no air bubbles and other obvious changes on the surface.
