Sherwin-Williams launches water-based epoxy
floor coating system for static control
Sherwin-Williams has launched the industry’s first static control
water-based epoxy floor coating system, the company said. The
General Polymers 3425E Static Control Water-Based Epoxy
Coating and 3424 Conductive Water-Based Epoxy Primer, developed by the company’s protective and marine coatings business, offer better performance and environmental attributes
compared to conductive solvent-based epoxy coating systems.
Sherwin-Williams 3425E Static Control Water-Based Epoxy
Coating is a high solids, two component epoxy coating designed as a coating or topcoat over standard flooring systems
to provide a static dissipative flooring system in the range of
106 to 109 ohms resistance. It is an ideal flooring finish in
computer rooms, circuit board assembly areas, hangars and
where highly sensitive electronic equipment is used regularly.
3425E Static Control Water-Based Epoxy Coating provides resistance to wear, abrasion and chemical attack from most common alkalis and acids.
The new water-based coating also can be used as a conductive
coating in the range of 25,000 to 106 ohms resistance when applied over the 3424 Conductive Water-Based Epoxy Primer. Conductive flooring is required in flammable material handling areas,
black powder storage areas and other areas where highly explosive materials are present.
In tests, the new water-based system has performed better
at static dissipation than solvent-based systems. In addition,
the coating is breathable, which makes it a better choice for
older concrete floors or where moisture has been an issue in
the past. Because the new primer and coating are low odor,
they can be installed in occupied spaces without disrupting tenants. The coating and primer are very easy to apply, can be
cleaned up with soap and water, and do not sacrifice dry time
and speed-to-cure when compared to traditional conductive
solvent-based epoxy systems.
Organa Gardens’ IGT develops Duraspeed
powder coatings for boat propellers
Integrated Green Technologies LLC (IGT), the powder coating and
equipment division of Organa Gardens International Inc., has completed field trials for its newly developed Duraspeed powder coating for boat propellers, drives (IPS), shafts, bow thrusters, trim tabs
and keel coolers. The trials were conducted under the control of
the Volvo Penta (Inboard performance system) warrantee facility in
Fort Myers, Florida. The coating was applied using the patented
IGT #100-B electrostatic thermal spray powder gun system, which
allows for the powder coating of parts without the need for a bake
oven. IGT’s proprietary foul release coating contains no environmentally harmful components and is designed to hinder the growth
of marine life on the surface of the parts while at the same time, due
to the smooth surface of the coating, allow for minimum resistance
between the part surface and the water. This feature, in test data
running in parallel with other smooth coatings, has proven to equal
or exceed all others both in RPM increase and fuel efficiency, the
company said. The minimum expected service life is several years
