- Alkyd coatings are a
class of polyester coatings derived from the reaction of an alcohol
(alkohol) and an acid or acid anhydride. Alkyd coatings today are
typically manufactured from acid anhydrides such as phthalic anhydride
or maleic anhydride and polyols such as glycerine or pentaerythritol and
are modified with unsaturated fatty acids to give them air drying
properties.
- The unsaturated oils
react with oxygen from the air which cause the oils to polymerize or
crosslink with each other. The drying speed of the coatings depends on
the amount and type of drying oil employed and use of organic
metal salts or "driers" which catalyze crosslinking between the
unsaturated oils used to modify the base polyester resin.
- Alkyd coatings are
produced in two processes; fatty acid process and the alcoholysis or
glyceride process. Higher quality higher performance alkyds are produced
in the fatty acid process where the composition of the resulting resin
can be more precisely controlled. In this process an acid anhydride, a
polyol and an unsaturated fatty acid are combined and cooked together
until the final product has achieved a predetermined level of viscosity
as suitable for its intended use.
- More economical alkyd
resins are produced from the alcoholysis or glyceride process where end
product quality control is not as paramount. In this process raw
vegetable oil, high in unsaturated component, is combined with
additional polyol and heated to cause transesterification of the
triglycerides into a mixture of mono- and diglyceride oils.
- Alkyd coatings are
typically sold in three classes; Long, Medium, and Short. Long oil
alkyds have a high percentage of drying oil content and are generally
sold as medium duty coatings for the consumer market. Medium oil alkyds
have less drying oil and have a higher percentage of large molecular
weight polyester backbone. They dry slower and are employed as high
gloss coatings and wood finishes. At the bottom end are short oil alkyds
where the percentage of drying oil is very low in relation to the base
polyester polymer or backbone chain. These coatings will not air dry or
harden unless heated. Short oil alkyds are employed as baking enamels
for finished metal products.
- Alkyd resins are used
in solvent-based paints. These paints incorporate driers which cause the
alkyd to crosslink with itself using atmospheric oxygen as the solvent
evaporates, resulting in a polymer that is no longer soluble in the
original solvent.Alkyds are also used in stoving enamels where they are
crosslinked with amino resins.
- The paint and coatings
industry is a mature market, growing at an estimated 2% per annum, or
about the same rate as durable goods. Although a number of paint and
coating manufacturers have captive resin manufacturing capabilities
today, increased costs of product reformulation and updating of resin
manufacturing processes to comply with environmental regulations are
causing a shift from captive
manufacturing to outsourcing.
- Alkyd resins and
copolymers are formulated and engineered according to customer
specifications for various purposes and the same product can be used in
different applications depending on the product's formulation.
