Over the years many zinc rich coatings have been formulated to mimic galvanic protection. This is generally attempted by infusing the resin binder with a large volume of fine zinc particles, anywhere from 60% to 95% by weight, in the dry film. Unfortunately the intrinsic insulating nature of the resin binder interferes with the inter-particle conductivity between the zinc particles. Besides curtailing the galvanic activity it severely limits the amount of zinc available for galvanic protection. Furthermore, the large infusion of the pigment reduces the amount of binder available for adhesion and film strength. The result is that besides inadequate galvanic action the zinc rich coatings have poor abrasion resistance and their ultimate performance is reduced to the level of a basic barrier coating.
Galvazin, a new and unique corrosion protection zinc rich coating, formulated by Liquiguard Technologies, offers a multi-modal corrosion protection system. It combines well researched solutions with cutting edge raw materials to combat corrosion on many fronts. As its basic strategy it uses a polymer matrix designed to provide intense vapor barrier properties along with strong metal adhesion. Galvazin is infused with 99% pure and very fine zinc particles.
The zinc particles are combined with cutting edge wetting and dispersing agents that aid dispersion and suspension preventing the hard settling of the zinc, a common problem with zinc rich coatings. In order to permit optimal galvanic action the formula is structured to activate a maximum amount of the zinc within the coating. This is accomplished via proprietary technology designed to overcome the limitations of the binder system, enhancing the inter-particle connectivity between the zinc particles and simulating the presence of monolithic zinc.
Galvazin is a low VOC coating with practically no odor. Surfaces that need to be safe guarded with Galvazin need not be pristine as is the case with galvanizing. Each gallon of Galvazin will provide 2 mils (50 ?m = 0.5mm) of dry _lm thickness. For optimal corrosion resistance, minimum of two coats of Galvazin are recommended. While Galvazin has a bright zing finish and is also available in 12 oz. aerosol spray cans. It is ideal for repairing damaged galvanized surfaces. For a clear, high gloss finish a single top coat of Liquiguard's corrosion protection clear coat, SilCote-CR is recommended. When using Galvazin in combination with SilCote-CR a single coat of Galvazin is considered sufficient for optimal protection.
The standard product has a medium gray color. The coating will become dry to the touch in 10 to 15 minutes at ambient temperature of 77°F. It will continue to cure over the next 72 hours and develop its optimal protective properties. Objects to be coated should be free of all surface dirt, loose rust and other contaminants. Galvazin has a spread rate of 450 square feet per gallon with a dry film thickness of approximately 2 mils. A minimum two coat application is recommended to achieve optimal efficacy when not applying a topcoat.
Due to its aesthetic surface appearance, Galvazin does not need a topcoat although the same is recommended in outdoor and aggressive environments. When Galvazin is used as a primer, Liquiguard Technologies' SilCote-CR, a corrosion resistant primer/topcoat, is an excellent choice for the topcoat. Galvazin can also be topcoated with commonly available water based acrylic and urethane paints. Allow Galvazin to dry completely before commencing with the application of additional coats or the topcoat. Alkyd and oil based paints should not be used as topcoats over Galvazin.
There are no fumes, odors or other hazards associated with the use of Galvazin. All normal precautions for use, storage and handling should be exercised as with any other paint product. Work area, tools, spills, etc. can be easily rinsed with paint thinners or mineral spirits. When applying Galvazin via spraying, make sure to protect surrounding areas from overspray. Wipe off excess and run-offs immediately with a damp rag or sponge. Galvazin can be ordered in single gallon and 5 gallon pails. Due to the very special nature of the galvacote additives please allow sufficient time for order processing. Galvazin is a proprietary product manufactured by Liquiguard Technologies and is available for order directly from our main offices located in Fort Lauderdale, Florida, USA.
