What is saturated polyester resin?
Saturated polyester resin is formed by the reaction of polybasic acids and polyols, and its feature includes excellent flexibility and hardness. It is mainly used in can coating, rolled steel, non-stick pan, ink, adhesive, PET coil, metallic baking paint such as automotive paint, and so on.
What resin is used for FRP?
Polyester Resins are the most commonly used in the FRP industry. Polyester is a viscous liquid resin combining polyester and a monomer solution, typically styrene. These resins are so popular because they are easy to use, cure fast and are tolerant of extreme temperatures and catalysts.

What is the difference between a saturated and unsaturated polyester resin?
The key difference between saturated and unsaturated polyester resin is that the saturated polyester resins have no double bonds in their main chain whereas the unsaturated polyester resins have double bonds in their main chain.
What is the difference between epoxy resin and polyester resin?
Epoxy is more resistant to wearing, cracking and peeling, and corrosion or damage from chemical or environmental degradation. Polyester is more fragile and useful for temporary fixes, or low-stress use. Epoxy is generally more expensive than resin, due to its strength and formulation requirements.
What is the cheapest type of resin?
For the record, latex is the cheapest casting resin available in the market.
What companies make resin?

Where is unsaturated polyester resin used?
Unsaturated polyester resin: applications Composite materials. Wood paints. Flat laminated panels, corrugated panels, ribbed panels. Gel coat for boats, automotive and bathroom fixtures.
Are all polyester resins the same?
There are several types and grades of polyester resin. DCPD Polyester resin is the most economical. Ortho is better for repairs because of its adhesion characteristics. ISO is a superior grade resin that has a higher heat distortion, better tensile strength, and has more corrosion resistance than ortho grade.
What is Orthophthalic polyester resin?
Orthophthalic resins (abbreviated as “Ortho resins”) are a type of unsaturated polyester resins broadly used for making composite components.
What is the difference between epoxy and polyester resin?
Fiberglass mat should not be used with epoxy because the binding material in the mat will NOT dissolve in epoxy resin.
How long does polyester resin take to harden?
How long does polyester resin take to harden? How long does polyester resin take to harden? During the curing process, the catalyzed resin goes through a series of stages from a liquid to a ‘soft gel’ in about 15 to 20 minutes, a ‘firm gel’ in 20- 30 minutes and finally to a ‘click-hard’ (cured) stage in 1 to 24 hours.
Can I put epoxy over polyester resin?
Therefore it makes no sense to bond polyester resin to cured epoxy as the bond will not be any better than polyester to wood, which is a weak bond at best. Epoxy layed up over roughened cured polyester will fare better. This is done frequently, in fact.
Which polyester resin to use?
Polyester Resins. Polyester resins are formed from the reaction of dibasic organic acids and polyhydric alcohols.
