Top 10 secrets of the paint industry
The coating consists of 4 basic parts: –
Binding material: It
is added in order to bind the color to the painted surface.
Dyes: Their purpose is
to transfer color and its stability on the painted surface. Moreover, they have
other purposes of applying them, such as stainless-steel paint, which is dyes
(colored, whether organic or inorganic, and white) and we can include fillers
under it and materials It expands and plays a role in coating formation.
Solvent: The volatile
part of the paint formulation is not an essential part of the formulation, but
is intended to dissolve the binder and adjust the viscosity of the paint.
Addition: It is like a
spice for paint, under which the following falls:
Desiccants: They are
added to speed up the drying process of oxidation-dried paints such as paints.
Anti-dandruff
materials: They are added to prevent the formation of a superficial layer on
the surface of the paint during storage of the package.
Anti-dandruff
materials: They are added to prevent the formation of a superficial layer on
the surface of the paint during storage of the package.
Resistant to settling:
They are added to paint to enhance the diffusion of pigments in the medium.
And the additives do
not depend on the aforementioned only, but there are more as well, such as
dispersants, flame retardants and UV absorbers.
Types of paints
The paint is divided
into a group of different paints that refer to distinct bases, which are as
follows:
Water based paint.
Oil paint.
To get to know them
more accurately, we first mention the water-based paints
It contains some of
the basic components as follows:
Polyvinyl acetate.
Polystyrene acrylic.
Acrylic acid
terpolymer.
Watercolor paints
Classification of
water-based paints:
Constructional or
constructive.
Decor or decoration.
Structural paint
There are basics
before starting, and these basics will be mentioned below:
The main water base is
called a sealant, and it is used as the basis for the surface before painting,
and moreover, it is very important because it prevents moisture and clogs the
pores in the concrete.
Followed by the
water-based putty, it performs the work of smoothing the concrete surface, as
well as filling cracks and gaps in the surface, as well as hiding the defects
of cement rendering, if any.
Finally, it is
waterproof that is used to isolate water, and it is commonly used on the roof
of the house, kitchen or bathroom to prevent water leakage, and it is installed
in a very special way in the building because most of the workers do not know
anything about its working principle, so water leakage occurs.
Decorative paint
Its types are:
Plastic paint or matte
water-based paint, and there are:
Without a glossy
finish.
Semi-gloss water-based
paint.
100% glossy water-based
paint.
It is generally used
as a finishing surface after foundation and putty.
Decorative paints can
be divided on the basis of the percentage of alkyd they contain as follows:
Glossy alkyl oil paint
50-60% (glossy paint).
In the case of semi-gloss,
it contains less than gloss by a proportion of approximately 30-40%.
And they are matte if
they contain a percentage of 20-25%.
It is worth noting
that it is used as a final coating on concrete, wood and iron surfaces.
