Initially, while covering surface
areas,liquid paint was the preferred coat
of choice. However, with time, most people have started preferring powder
coating over other options.
This is
because, the three-step application
process used by the powder coating companies make the coats last long and provide an even finish over
surfaces.
For powder coating, a free-flowing dry powder is applied
thermostatically on the surfaces, and then it is heated and cured to form a
hard skin.
There are various types of powder
coating used by powder coating services
for the surfaces. Amongst them, the 6 most common types are as follows:
Type 1: Epoxy
type:
The first kind of coating to become
widespread commercially, epoxy type powder coating is the best for interiors.
It provides excellent corrosion and chemical resistance
offeringlong-term durability. The best for covering metal surfaces, it is the coat
of choice for various industrial equipment.
Type 2: Polyester
type:
Powder coating companies popularly use polyester type powder coating for automotive. The two types of polyester
coatings- TGIC and Urethane, offer great chemical resistance, impact resistance
and flexibility. Also, because of their resistance to UV, they are ideal for
exterior use.
Type 3: Acrylic:
If you are looking for a thin and
clear coat, acrylic is the best for you. This powder coat, used especially for cars and other automotive, offers
excellent clarity and makes the surfaces chip resistant. It is even used as an additive for other types of
powder coating.
Type 4: Fluoropolymer:
This type of coating is the best for
application on the exterior of buildings because of its superior weathering
properties. Since it retains its colour and gloss for a long time, it is ideal
if you are looking to coat your doors, windows, wall, etc. However, since it is
difficult to bond while producing metallic powders, it needs an application of
primer beneath it.
Type 5: Epoxy-Polyester
hybrid type:
The powder coating services mix both epoxy and polyester type powder to
create this hybrid. Even though it mostly retains the properties of epoxy, it
comes with superior weather resistance properties. The two types of resins are
mixed in different ratios to enhance the properties of either epoxy or
polyester. This hybrid mix is ideal for application over furniture, stoves,
shelves, washers, etc.
Type 6: Urethane's:
Urethane resins are quite similar to
polyesters in nature. They offer a smooth and even finish, with high corrosion
and chemical resistance. This type of powder coating is vastly in use for air conditioners, doorknobs, car rims, etc. The reason it is so popular for coating doorknobs,
oven knobs, etc. is that it prevents impressions of fingertips on objects.
So, choose from any of these
powder-coats and say goodbye to liquid coating today!
