FAQs | ACP Sheets & Metal Composite Panels | Aludecor

The width of Aludecor ACP is 1220 mm and length can be up to 6100 mm. Customized width of 965 mm is also available on request.

We source Aluminium Alloy from Hindalco, and PVDF paint from PPG, AkzoNobel, Berger Becker and Nippon

Dupont Adhesive of Bynel series is used as an Adhesive Film.

• AA 1100/AA 3003: The alloy of this grade is a manganese alloy which has a minimum tensile strength of 120 N/mm2 and to be used for buildings below 10 meters.

• AA 3005/ AA3105: the alloy of this grade is a magnesium and manganese alloy which has a minimum tensile strength of 150 N/mm2. This is to be used for external façade solutions as magnesium decreases the chances of oxidation of aluminium and the tensile strength enables it to handle wind loads of 2.25 KPa easily.

• AA 5005: this alloy has the magnesium content nearing to 1% which is required in coastal regions for not letting the aluminium oxidize and paint to sustain high salty moisture content. Also, it has the minimum tensile strength of 150 N/mm2 which enables it to handle wind loads of 2.25 KPa.

Tensile strength of the material is defined as strength required to resist the tensile forces acting on any material. It is expressed as Force per unit area. Tensile strength is expressed as N/mm2. When load is applied on a body, the body experiences compression and this generates an equal resisting force to regain its shape and this is known as Tension or Tensile strength

There are 5 types of coatings used:

• PVDF

• Lumiflon

• SDP (Super Durable Polyester)

• HDP (High-Density Polyester) Polyester

For measuring the coating properties AAMA 2605 is used for 10 years warranty, AAMA 2604 for 5 years warranty and AAMA 2603 for interiors

PVDF stands for Polyvinylidene Fluoride. It is a resin added to paints to increase its UV – resistant properties. This happens due to the C-F electrovalent bond

The performance of paint increases with an increased thickness under a stipulated range set by AAMA. Two coats PVDF has a durability of 10 years and by increasing it to three coats the durability increases by 5 to 10 years.

The paint of the ACP will peel off in case of the following reasons:

• Improper cleaning

• Incorrect Routing

• Contamination of coil

• Inappropriate cutting

Metallic colours obtain their gloss from organic pigments. These pigments have higher quantity of polyester contents compared to PVDF which provides the gloss, however, it reduces the life of the paint when used in the exterior. This is the reason why metallic colours have lesser life than solid colours. They lose their gloss much early than solid colours. This is in accordance to AAMA 2605 which states that in 10 years gloss remaining should be 50% of the original
