NOF’s new range of Geokote coatings provide optimal corrosion protection.

MGI Coutier, a manufacturer of door check straps for the automotive industry, parts that are highly stressed, wanted to develop a very high performing anticorrosion solution, and in the end relied on two solutions: the application of Geomet 321 Grade A coating and a clear or black Geokote topcoat.

“We wanted a new coating combining
both strong corrosion and mechanical re-
sistance,” said Sébastien Leclerc, project
manager at MGI Coutier. “The Geomet 321
zinc flake coating with a Geokote topcoat
provides us with the compromise sought re-
garding the preservation of the corrosion
performance after the numerous mechanical
stresses exerted on parts. From the tests per-
formed, we have selected two options: a
black topcoat and a clear topcoat.”
NOF said the Geokote topcoat is also
particularly well adapted for manufactur-
ers and users of fasteners (screws, nuts,
tightening clips, etc.) by providing them
optimal strength and mountability prop-
erties. It enables among other properties
the ability to avoid the stick-slip effect
when tightening.

The range of Geokote topcoats is available worldwide and can be used with dip or spray processes on the lines of NOF’s global applicators network.

New Spies Hecker Permasolid 2.1 Surfacer 5157 Spies Hecker has introduced Permasolid 2.1 Surfacer 5157 is a 2K acrylic urethane with low VOC levels and is designed for use with both waterborne and solvent-borne base coats.

Permasolid 2.1 Surfacer 5157 is ideal for refinishers because of ease of application and increased productivity the company said. Spraying requires two to four coats and flash-off time is five to 10 minutes between coats. Its leveling properties means less sanding is required.

“Permasolid 2.1 Surfacer 5157 gives
shops a low VOC, productive surfacer
that will help increase productivity and
improve final results,” said Debbie Curry,
product manager, North America. “This
new surfacer is not only fast and easy to
spray, it also provides good absorption of
overspray and exceptional feather edge
capabilities, enabling technicians to
achieve optimal final results.”
Permasolid 2.1 Surfacer 5157 is avail-
able in white and dark gray.

Based in Cologne, Germany, Spies Hecker is one of the world’s leading manufacturers of refinishing paints.

Dunn-Edwards improves Suprema interior flat and velvet paint Dunn-Edwards has improved its Suprema product line. The Flat and Velvet finish levels ( 10 and 20) now provide better hide, burnish resistance and touch up that will go a long way to ensure that painting professionals can provide the best possible interior paint for their client’s homes the company said. The high quality resins in its formulation provide better scrub resistance by creating a harder film. Suprema has excellent flow and leveling because it uses a special thickening agent that interacts better with the resin particles to allow the paint film to flow better. This ensures a smooth, even finish. Suprema is eco-friendly, ethylene glycol (EG)-free and produced in the

nation’s only LEED Gold-Certified paint manufacturing plant. Suprema is ultra-low VOC at 50 grams per liter, and has very low odor both during and after application. The improved Suprema Flat and Velvet are now available in Dunn-Edwards’ stores.

PPG launches new CRE Series
primers

PPG Commercial Coatings has introduced an enhanced version of its CRE Series cor-rosion-resistant epoxy primers. The new primers replace all versions of the CRE products currently sold in North America. The CRE-X21 Series primers provide a range of performance features that include improved chemical resistance, enhanced corrosion protection, a broad 96-hour recoat window, and excellent adhesion to galvanized, galvaneal and stainless steel as well as to current compatible substrates. Also, with a 2.1 lbs/gal blended VOC, the new series meets current regulations in the U.S. and Canada in PPG target markets.

“This series of greatly improved
primers is the result of new raw material
technology we are utilizing at PPG,” said
Steve Podlas, marketing manager for PPG
Commercial Coatings. “We have com-
pletely redesigned both sides of the
primer/hardener package in making the
improvements.”
According to Podlas, the CRE-X21 Se-
ries primers offer higher film build capabil-
ities and excellent sag resistance. The fill
properties make the primers an ideal choice
for application over sandblasted profiles.
The primers also provide a smoother ap-
pearance allowing for a better finish ap-
pearance after the topcoat is applied.

The CRE-X21 Series primers are offered in three standard colors—black, gray and white—in addition to a tintable version. They are intended for use on trailers, cranes, service bodies, cryogenic equipment, and a variety of other manufactured items. The primers can be applied using conventional equipment, pressure pots, airless, air-assisted airless, or electrostatic spray equipment.
