Polyester Coated Aluminum Coil

Polyester Coated Aluminum

LITONG are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Polyester coated aluminum can create aesthetics and design concepts, allowing architects and builders to create eye-catching and stunning structures as it can be adapted to any shape.

It is an anti-UV paint that uses high molecular polymer as monomer and adds alkyd resin. It can be matte or glossy depending on your needs. The dense molecular structure makes the dot surface glossy and smooth, ensuring good printing effects on the paper surface.

Polyester Coated Aluminum Coil

Polyester Coated Aluminum Coil is a versatile material widely used in construction, transportation, and other industries. The aluminum coil is coated with a polyester resin layer, offering durability, resistance to environmental elements, and an attractive finish.

We use advanced equipment and technology to produce polyester (PE) coated aluminum coils. Continuous roller coating to avoid color difference. In a baking chamber at 240 degrees Celsius, polyester paint can form a solid, high-performance protective layer on the aluminum surface to prevent corrosion and contamination. The polyester layer thickness is 16±1μm.

Applications of Polyester Coated Aluminum Coil

• Polyester PE coated aluminum coils are used to produce aluminum ceilings, aluminum tiles, aluminum plastic panels, aluminum honeycomb panels, aluminum insulation panels, aluminum roller shutter foam insulation slats, aluminum gutters and downspouts, etc.

• Polyester PE coated aluminum coils are also suitable for interior decoration and advertising boards.

Film thickness
The proper paint film thickness is critical to the long-term performance of the paint film. For primers, low film thicknesses may result in premature corrosion or poor adhesion. For topcoats, low film thicknesses may cause premature failure due to weathering.

Color
One of the main reasons for purchasing prepainted aluminum coil is for its various bright colors. Since it is common for customers to match prepainted metal to other components of a building, matching specified color standards is important to the aesthetics of the final assembled product.

Color must be consistent across the width of the strip and different aluminum coils. Many factors can affect color: paint formulation and quality, film thickness, substrate color, curing temperature (PMT) and dwell time in the curing oven, and even contamination from other paints.

Gloss
Gloss consistency is important to provide clients with a uniform look. The final product may consist of several components made from different coils. If the gloss level is not consistent, the final product will have a poor appearance and will not look good.

Adhesion
Several tests are performed to check various aspects of adhesion, including T-bend, impact and various scratch tests. One of the main advantages of prepainted coil is that it can be formed after painting, so these tests are very important to ensure that the paint will not be damaged or removed during subsequent processing.

Factors that affect adhesion include paint formulation, film thickness, curing temperature (PMT), line speed, quality of treatment, plain aluminum coil quality, and cleanliness.

Curing degree
Curing is a term referring to the degree to which a material transitions from its initial state to its final cured state.
All coil coatings are baked, during which two things happen:

• The solvent in the paint evaporates and burns in the afterburner.
• Chemical reactions in the paint film bring the resin molecules together (polymerize or crosslink) to form a strong crosslinked solid paint film.

Routine maintenance can go a long way in protecting the surface of your coated aluminium coil. Regular inspections can help to identify any potential problems, such as chips or scratches on the surface. If any such issues are found, they should be addressed as soon as possible to prevent them from becoming larger problems that may require more extensive repairs. Following these simple tips can help to ensure that your coated aluminium coil remains in good condition for years to come.
