The effect of
sunlight on paints
Surely it is worrying matter to maintain your
stained and painted walls continuously because of the damage that may happen to
them because of their prolonged exposure to the sunlight. Anybody of us wants
to spend at once and forget and most of us don’t want to buy paints every
period of time and go to the specialist to apply them on his walls and you know
more money will go out from your wallet. So by this way decoration is so
costing. But no it is not like that and I will tell you at the end of that essay
after discussing how sunlight can effect our paint negatively.
We should understand the harmful components of
the sunlight and even which may be existing in the artificial lights of our
lamps at home. The first one of it is ultra violet rays UV. Such kind of rays
can not be seen i.e. invisible one and its damaging role is in its ability by
breaking molecular bonds between the atoms which forms the paint chemicals and
pigments. How does that happen ? The electrons which are existing in paints
will absorb the UV photons and this will lead them to be ejected from their
orbits away from the atoms and so the bonds between the atoms will be broken.
The result is a film of chalk over the surface of paints and the surface which
is behind the paint will be dried to the degree that it can be easily broken.
The surface of paint too will be rippled.
The
infra-red rays will do a heating effect
over the surface of paint. The outer layer of paint will dry quickly while the
under layer will be softer and a result of that such dried surface will be
stressed and make cracks. Also infra-red ray blistering heating will cause the
surface of paint to have blisters. Wind and rain will do its job by removing
such blisters and so ugly patches on the surface of paints will appear.
Fading of color is a problem too that may
happen over years due to the ionization of color which happens as the previous
effect we discussed about UV.
Anyway don’t worry as new science in the field
of chemistry has invented new products that can withstand the harmful impacts
and effects of sunlight. Water-based paints is the solution. They are kind of
paints that is mixed with water and after drying will withstand water. The
leading Turkish company in water-based paints izoyapi has taken into
consideration such problems which tired the customers about the harmful effect
of sunlight. They are producing water-based paints , primers and putties that
have acrylic surface or plastic or silicone ones. Their products contain
chemicals that made their products waterproof as well as sun proof. Varied
types of paint. Color your walls and forget for long years till you think to
change colors. Their surfaces don’t crack . blister or ripple.
