AUTOMOTIVE PAINT TECHNOLOGY Today's painting systems offer an
innumerable barrage of paint types. It is often very difficult to determine
what type of paint is actually on the vehicle. Even the expert paint and
body man will have difficulty recognizing what type of paint was used. Many
of today's paints are of either an alkali base, water base or solvent based
product. These types of paint cover acrylic enamels, acrylic lacquers,
Imron acrylic urethanes (alkyd enamel found mostly on foreign cars) Glasurit,
polyurethane, non clear coats and 2 or 3 stage clear coat paints. With such
a wide variety of paints it is far easier to learn how to polish these paint
systems rather than learning how to mix and match paint! Now let's take a look at the different type of sealants used to condition and protect the paint finishes. WHAT IS A NATURAL SEALANT? One of the most confusing and misunderstood issues, even in the professional world of detailing, is that technically there are two types of sealants. The standard wax type sealants are made of mostly naturally occurring base products like carnauba, bee's wax, and monton waxes that tend to deteriorate at a rate much the same as paint develops oxidation. Generally speaking, if the owner of the vehicle takes relatively good care of their vehicle by using the proper washing products and sealants the paint finish should go through a complete reconditioning of the paint every 3 to 4 months. WHAT IS A SYNTHETIC SEALANT? Synthetic sealants are simply test tube and manmade products, and when combined create a longer lasting and more durable finish than its natural counter product. Let's take, for example, an acrylic teflon, or polymer product. These are both synthetically derived products but have been proven to outlast ordinary wax products. The physical appearance of the products, when applied to a painted surface are almost identical. However, since synthetic based sealants contain little or no natural waxes which are soft and tend to melt at a much more rapid rate, the life expectancy of a synthetic sealant is far greater. The average life expectancy of a synthetic paint sealant, provided that the vehicle has been well maintained, is between 6 months to 1 year. SILICONES Many of today's advanced products contain a
small amount of silicone oil. Silicones were first developed in Germany in
World War II for the purpose of substituting crude oil with a cheaper and
more readily available artificial lubricant. Later, scientists discovered
that silicone was an excellent substitute for paraffin wax in the pre-1960
years. Paraffin is a derivative of crude oil, and is still used as a
lubricant agent when blending carnauba based products. Silicones proved to
be far superior to paraffin wax since they resist high temperatures and
provide a much higher gloss finish. WAXING - SEALING - GLAZING Waxing and sealing are the final stages in
buffing a car to achieve its most durable shine. A good wax job is what
gives the paint its final brilliancy, and hard protective seal, to protect
the vehicle's finish from harmful enviromental effects due to ultra-violet
radiation, corrosives, and other harmful chemicals created both
synthetically and by Mother Nature herself. A good wax job must have
lasting properties not only to protect the finish from the continuous
onslaught of harmful elements, but to retain its reflective characteristics
and depth of gloss. A good wax or sealant possesses hydrophobic
characteristics or in laymen's terms, the film of sealant or wax helps the
painted surface reject water. This is seen by droplet or a beading action
on the painted surface once the finish has been treated. Today's liquid
waxes have become more sophisticated using a blend of high grade silicones,
polymers and high grade hardening carnauba and monton waxes. Monton wax is
a coal derivative type of wax and is sometimes found in the more expensive
types of polishes and waxes. Carnauba wax is the hardest natural wax known
to mankind, and has an unusually high melting point of 185 deg F. It comes
from a species of Palm that grows in Central and South America. Its natural
color is grey before it is processed for commercial use. Carnauba in its
natural state is a vegetable plant and when it is extracted is very flaky.
These flakes are then formed into blocks by mixing the flakes with a
lubricating agent like parffin, silicone or solvents. Carnauba wax is
unparalleled in giving a paint the deepest, hardest and most dazzling finish
over all other wax products, even today's sophisticated "high tech" paint
sealants. An automobile treated with carnauba wax requires lass mainenance,
because of its prominent durability even after many washings. THE END
