Epoxies first appeared in 1942 when epoxy
resins were discovered. Two part epoxies were introduced in 1947
and earned a reputation for having excellent durability, as well
as high chemical and corrosion resistance. Epoxies are especially
effective in corrosive environments in that they act as a barrier
and filter of ions contained in corrosion cells.
The need to cure two part epoxies at temperatures
below 40F was solved in the 1970s with the advent of amine
cure agents. This remained the dominant technology until the
late 1990s when 100% solid epoxies cured with innovative
cycloaliphatic amines entered the marketplace.
When properly formulated these new epoxies
exhibited excellent resistance to highly aggressive petro-chemicals,
solvents, fatty acids, as well as hydrochloric and concentrated
sulphuric acids.
Proprietary curative agents for these new
epoxies can impart a balance between rapid cure and crosslink
density allowing the formulation of high performance environmentally
friendly coatings
Epoxy
Fact Sheet
IAG's solventless 100% epoxy coatings offer
the following advantages over the other coatings
* "0" VOC's
* absence of flammable or combustible solutions
* high build capability
* superior chemical and corrosion resistance
* ease of application
* cost effective
Although the cost per gallon of IAG's coatings
may be higher than other coatings the overall applied cost of
these coatings is lowered by the following factors:
* surface tolerant and self priming features
allow single-coat application
* less coating losses due to over spray
* no coating volume losses due to solvent
or water evaporation
* no special VOC containment equipment
required
* high-build characteristics reduce labor
* no special spray or heating equipment
needed
