A covering that is applied to the
surface of an object.
Eg: Industrial Flooring,Waterproofing
Also called "epoxy" or "polyepoxide".
Thermosetting Polymer, Copolymer
High Mechanical Properties: large cohesive force
Good Adhesive Performance: great number of polar group
Excellent stability: without impurities(base and salt)
Flexibility and diversity in Designing
Because of the stability and mechanical properties, epoxy resin
coating owns great chemical and physical resistance.
“Marketability” of the Epoxy
Epoxy coatings are chemically resistant to water,
saltwater, organics, and acid
Also resistant to mechanical damage (scratches)
Also does not deform at high temperatures, due to
its thermoset polymer nature
Thanks to this wide variety of desirable properties
and applications, epoxy coating are marketed in
industrials, commercial, and residential sectors
The Industry of Epoxy Resins
China produces 30% or the worldwide market.
$5 Billion industry in North America
Hexion (Shell Development Company)
Dow Chemical Company
Huntsman Corporation’s Advanced Materials
Some current applications are on “under-the-hood”
automotive components, floor coatings, underground
tanks/pipes/cables, electrical connectors, circuit boards,
adhesives, structural support additive in high stress areas
like wind turbines and aerospace frames
Protective coatings are therefore usually based on
primers containing a linseed oil or alkyd binder
and anti-corrosion pigments such as red lead, lead
chromate, zinc chromate, potassium zinc
chromate, and zinc dust.
The completed coating system will have a dry
thickness of 5 to 10 mils.
Waterproofing – roofing, sealing, bonding
Concrete repairs – weather, lightweight yet
Metal protection – corrosion resistant
rubber carpet: playgrounds, water parks,
bathrooms chemical resistant and hard-wearing
non-slip flooring: stadiums, gyms, industry
As for Epoxy Resin Coatings...
Epoxy coatings were developed for heavy duty
service on metal substrates and use less energy
than heat-cured powder coatings.
Their low volatility and water clean up makes
them useful for factory cast iron, cast steel, cast
aluminum applications and reduces exposure and
flammability issues associated with solvent-borne
Epoxy Resin Coatings' Performance:
As a result, epoxy resin coatings has been
widely used in many different conditions.
