A Comprehensive Guide to Understanding Exterior Aluminium Composite Panel Coatings

2023/07/10

Exterior aluminium composite panels (ACP) have become increasingly popular in recent years as they offer numerous advantages over traditional building materials. Their durability, versatility, and aesthetic appeal have made them the top choice for architects and builders in modern construction. However, the performance of ACP coatings on buildings in exterior applications can vary widely, based on the quality of installation and the type of coating applied. Therefore, it is essential to understand the different types of coatings available for exterior ACPs before selecting the ideal one for your project. In this guide, we will provide you with a comprehensive understanding of the different types of ACP coatings that are available and tips to help you make the best decision for your project.


Understanding Aluminium Composite Panels (ACP)


Before delving into the types of coatings available for ACPs, let's first understand what ACPs are. ACPs are lightweight sandwich panels made of two aluminium sheets bonded to a core of non-aluminium material. These panels are highly durable, have excellent insulation properties, and can be customised with different finishes, colours and patterns according to a client’s needs. They are widely used in commercial, industrial and residential buildings around the world.


Different Types of Coatings for Exterior ACP


1. PVDF Coating


Polyvinylidene fluoride (PVDF) coating is the most popular type of coating used for exterior ACPs. PVDF is a resin-based fluoropolymer that provides excellent weather resistance, colour retention, and durability. PVDF coatings are resistant to fading, weathering, and damage due to exposure to UV radiation. They are available in a wide range of colours and finishes, including metallic and pearlescent finishes. PVDF coatings are also easy to clean and require minimal maintenance, making them a popular choice for exterior facades and cladding.


2. Polyester Coating


Polyester coatings are also widely used for exterior ACP applications. They are generally less expensive than PVDF coatings and come in a wide range of colours and finishes. Polyester coatings are ideal for buildings with low maintenance requirements, as they tend to fade and dull over time, making them less suitable for high-traffic or exposed areas.


3. Nano Coating


Nano-coating technology has been in use for more than a decade, but it is only recently that it has found its way to the construction industry. Nano coatings are made up of tiny particles that are around 1 billionth of a metre in size. They are applied like a paint but form a dense network of nanoscale particles, which provide a very fine and an almost smooth surface. Nano coatings are known for their hydrophobic properties, which makes them resistant to water, oil, and other liquids. They offer superior UV resistance and protect the ACP surface from dirt, algae, and other air pollutants.


4. FEVE Coating


Fluoroethylene vinyl ether (FEVE) coatings are also popular for exterior ACP applications. These coatings are highly durable and provide excellent weather resistance, allowing them to last for decades without significant fading or deterioration. FEVE coatings are also resistant to chemicals, UV radiation, and abrasion, making them an ideal choice for areas with high traffic or exposure to environmental pollutants.


5. Anodized Coating


Anodized coatings are created by electro-chemical processes, which alter the surface of aluminium to create a hard, durable, and corrosion-resistant layer. Anodized coatings are more expensive than other types of coatings and are less flexible in terms of colours and finishes. However, they offer superior hardness, durability, and resistance to abrasion and corrosion. Anodized coatings are typically used for architectural accents or low-traffic areas and can also be used to create metallic finishes.


Guidelines for Selecting a Suitable Coating for ACP


Here are some important guidelines that will help you in selecting the right coating for your ACP project:


1. Consider the Location


Different types of coatings respond differently to various environmental factors such as humidity, wind, temperature variation, water, and air pollutants. Therefore, the location of the building should be considered in selecting an appropriate coating.


2. Consider Longevity and Maintenance Costs


Longevity and maintenance costs should be also considered when selecting the ideal coating for the ACP. Costlier and higher-quality coatings require less maintenance, and thus, additional long-term savings should be considered.


3. Colour and Finish


The colour and finish selected is a crucial aspect of coatings, as it defines the overall appearance and aesthetics of the project while ensuring the project's durability. Because of the availability of a wide range of colours and finishes for different types of paint coatings, the right choice of colour and finishes should be selected.


4. Fire Safety


In selecting a coating for exterior ACP, the fire safety risk of the building should be considered. Appropriate coatings that meet national and international fire safety regulations should be selected.


Conclusion


Exterior aluminium composite panels are becoming increasingly popular due to their simplicity, versatility, and durability. Coating is an integral part of these panels and ensures their longevity, easy maintenance, and aesthetic appeal. The type of coating selected will profoundly affect the product's durability, appearance and life cycle cost. Nevertheless, there are a wide range of types of coatings available, so you must consider the location, longevity, colour and finish, fire safety, and maintenance costs of your project to make an informed decision about your coating selection.
