Polyester resin is a liquid that hardens when mixed with a catalyst like MEKP. It is widely used in marine and automotive industries to form hulls, body panels, and other parts due to its strength and flexibility. Polyester resins are inexpensive, offer some corrosion resistance, and are forgiving to use compared to epoxies. They are easy to use, fast curing, and tolerant of temperature variations. Properties can be formulated to achieve the required strength and weight targets for a particular application.

1. POLYESTER RESINS

2. Polyester Resin is a liquid which will
cure to a solid when the hardener is
added. It has been specially
formulated to cure at room
temperature. The hardener, MEKP
(Methyl Ethyl Ketone Peroxide) is
added to cure, or harden the resin.

3. Polyester resins are popular and widely
used, especially in the marine industry to
shape and form hulls and outer layers of
ships. Other industries also employ
polyester resin thanks to its numerous
beneficial properties. They are used in
the auto industry, as an adhesive and
even as wood filler. The following are
some of the properties exhibited by
polyester resins.

4. Polyester resins are, across the board,
pale in color. This could be a pale gray
color to a dull and diluted white.

5. Polyester Resins are the most widely
used resins in the composites industry.
Sometimes referred to as Fiberglass
Resins, Polyester Resins are less
expensive, offer some corrosion
resistance, and are more forgiving than
epoxies. The majority of all fiberglass
parts are constructed using Polyester
Resins because they are easy to use,
fast curing, and tolerant of temperature
and catalyst extremes.

6. Technical Details:
A wide range of surface qualities are
possible to satisfy different application
needs, from a cosmetically beautiful
Class A automotive/truck body panel to
a rugged underground utility
box. Polyester formulations offer
tremendous flexibility.

7. Properties can be formulated for your
product specification targets. Typical
SMC properties with standard 28% glass
reinforcement result in 12,000psi tensile
strength and 25,000psi flexural
strength. Strength-weight ratio is very
good and because of its low density
(from 1.70 grams/cc formulated) it often
replaces metallic parts that are close to
five times heavier.

8. Polyester resins are unsaturated
synthetic resins formed by the reaction
of dibasic organic acids and polyhydric
alcohols. Maleic Anhydride is a
commonly used raw material with diacid
functionality. Polyester resins are used
in sheet moulding compound, bulk
moulding compound and the toner of
laser printers.
