ACP is known as Aluminium Composite Panel. It is made out of Aluminium sheets.
LPDE is known as Low Density Polyethylene. It is one of the core materials used in the Aluminium Composite Panels.
Protection Film, PVDF/Polyester Resin Based Coating, Primer Coating (Used in case of PVDF Only), Aluminium Coil, Adhesive Film (Polyolefin), Polyethylene Core (LDPE), Service Coating (Anti-corrosive)
It is accessible in 4mm, 3mm and 1.5mm. 5mm and 6mm are accessible on solicitation.
The width of ACP is 1220 mm and length can be up to 6100 mm. Altered width of 965 mm is likewise accessible on request.
The thickness of the paint fluctuates with the sort of paint utilized:
Polyester: 15-18µ (µ-micron)
PVDF: 25-28µ, goes up to 30-35µ when given the third coat
We source Aluminium Alloy from Hindalco, and PVDF paint from PPG, AkzoNobel, Berger Becker and Nippon
Dupont Adhesive of Bynel arrangement is utilized as an Adhesive Film.
The different dimensional tolerances of aluminium composite panels are as follows
Width – +/- 2.0mm
Length – +/- 4.0mm
Thickness +/- 0.2mm
Bow maximum 0.5% of the length/width
Squareness maximum 5.0mm
ACP as a building material is utilized to improve the look and feel of a building. Its purpose is to give an all-around characterized, savvy and an advanced look to your façade.
Aluminium composite panels are Fire resistant relying upon the kind of core material being utilized. Generally Mg(OH)2 is added as a non- flammable material.
Timex Bond has taken EN 13501-1 for flammability and response to fire, for protection from fire on the total framework Timex Bond has 2 hours ASTM E119 rating. These ratings are in contrast with BS 476, ASTM E84, NFPA, DIN 4102 and so on
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 utilized for structures under 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 utilized for outer façade arrangements as magnesium diminishes the odds of oxidation of aluminium and the tensile strength empowers it to deal with wind heaps of 2.25 KPa without any problem.
AA 5005: this alloy has the magnesium content approaching to 1% which is needed in coastal front districts for not allowing the aluminium to oxidize and paint to support high high salty moisture content. Likewise, it has the minimum tensile strength of 150 N/mm2 which empowers it to deal with wind heaps of 2.25 KPa.
Tensile strength of the material is characterized as strength needed to oppose 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 encounters compression and this generates an equal resisting force to regain its shape and this is known as Tension or Tensile strength.
Flexure implies bending or bending strength of material. This is again determined utilizing bending strength formula.
ASTM is known as American Society for Testing Material.
There are 5 kinds of coatings utilized:
SDP (Super Durable Polyester)
HDP (High-Density Polyester) Polyester
AAMA 2620/2605 is followed. AAMA is known as American Architectural Manufacturers Associations.
For estimating the coating properties AAMA 2605 is utilized for 10 years warranty, AAMA 2604 for 5 years warranty and AAMA 2603 for interiors.
PVDF is known as Polyvinylidene Fluoride. It is a resin added to paints to build its UV – safe properties. This occurs because of the C-F electrovalent bond.
It has a scratch resistance of up to 4H.
The performance of paint increases with an increased thickness under a specified 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.
No, the paint weathering has nothing to do with the sub-surface.
The paint on the ACP may peel off due to various reasons, to name a few:
Metallic colours get their shine from natural pigments. These pigments have higher amount of polyester substance in comparison to PVDF which gives the gloss, nonetheless, it decreases the existence of the paint when utilized in the exteriors. This is why metallic colours have lesser life than strong colours. They lose their gleam 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.
