Painting is sometime known as coating, it is a necessary to surface protection, ranging from building to industrial objects, from structural to non-structural material. Paint functions as a protective layer to block incoming of foreign substances such as sunlight UV, rainwater and chemical. It is important to apply these protection layers because without them, the internal bodies’ properties might have been affected due to the penetration of external materials. Aathaworld as a comprehensive coating specialist in Malaysia, we would like to introduce what is all about coating, types of paint or coating, function and application.
What is Paint
Commonly agreed by painting specialist in Malaysia, paint is a kind of liquid, liquefiable or some other type of composition where thin layer applied on the substrate convertible to solid film. It is highly suitable not only to provide protection of objects, also for colouring and creation of texture onto the surface. Paint is normally produced and stored in liquid form and become solid after dried, it can also be in gas or solid powder form where these are depending on what are their application and results required.
Industrial and automotive application are commonly being observed for this type of solid paint, this paint works in a fine powder form before high temperature baking by coating supplier in Malaysia. The melting process will create adhesiveness of the powder onto the surface, this is also known as “powder coating”. Powder coating also work in a free-flow way, it does not need solvent to keep filler and binder parts like liquid paint does, in a liquid suspension form.
Theoretically, it is spread on using electrostatic method, before it is being cured under heat to permit flowing happens which subsequently forming a “skin layer”. Coating specialist in Malaysia claims that powder can be a thermoset polymer or thermoplastic that applied to generate a tough layer finish which is harder than traditional paint. Common use of powder coating is on metals, for example, aluminium, hardwares, spare parts as well as Medium-Density Fibreboard (MDF) through modern technique.
It is also known as “Spray Painting” where the liquid paint or suspended solid paint is sprayed on the substrate. The few advantages of this spray painting method consist of air mechanism application is involved where no solid item to touch on the object that intended to be painted, no sharp and obvious lines will be formed since the paint distributes evenly throughout the whole object, paint volume can be adjusted easily and therefore enable small painting job to be carried out. According to paint supplier in Malaysia, spray paint has also some other benefits that cannot be substituted easily with other type of paint. This paint shall be sprayed with solvent chemical to ensure smooth spraying process can be done. Hot spray, airless spray or hot airless spray as well as any electrostatic spray are those methods that shall be used depending on the circumstances.
This is one of the most common paint type that allows multiple application method, such as blades, brushes, scrapers, other instruments, paint rollers, body parts such as thumbs and fingers. For instance, roller application for liquid paint normally have adjustable pole length handle. Coloured paint requires two layers of coating if roller is being used, in order to achieve identical colour tone. Painting specialist Malaysia says that thicker nap roller also being utilized during painting job for uneven surfaces. For many substrates, primer need to be applied first before top coat (single or double layers) to ensure perfect adhesiveness and its durability. Paint supplier in Malaysia must always advise the user to handle cautiously, any inappropriate disposal will cause pollution.
Other Product Varieties
As per mentioned, primer works as a preliminary layer coat that applied on substrate before top coat is painted on; besides it works as an enhancer of the adhesion, additional protection layer to the painted surface, overwriting the existing painted colour and hiding the stain on existing substrate too. At the same time, paint supplier in Malaysia does offer also emulsion paint which these are non-solvent based paint which contains minimal toxic, convenient in application, cleaning, fast drying and cost effective since it made up mostly by water (also known as water-based paint).
There are also different paint finishes for various purposes such as wider coverage, durable washability, specific areas such as wall or ceilings in terrible shape; the paints that mentioned here are matte finish and flat finish based paints. Satin and eggshell finish are two other painting finishes can be provided by painting supplier in Malaysia, long-lasting washability, moisture resistant and water repellent, very suitable to bathroom when eggshell finishes are being selected, it is also not easily to get peeled off in wet environment. However, eggshell is more as competitive as pearl or satin finish when come to imperfection hiding on surfaces because the latter is more shining; they are more suitable to be applied to kitchen, furniture and prevent stain, moisture and dirt from penetrating into the surface.
