The most effective and long term corrosion protection is offered via galvanizing wherein molten zinc is bonded with the steel profile forming a tenacious zinc layer on the surface. Zinc provides protection via a process called galvanic action. It passivates the steel and sacrifices itself by interacting with atmospheric moisture, thus preventing corrosion of the steel. The single greatest drawback to galvanizing is that it can only be performed at the galvanizing plant and thus precludes protection for existing structures. 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 Application

Galvazin is extremely easy to apply using a brush, roller or airless sprayer and will air dry to form a tough tenacious film. 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. Because of 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.

Galvazin- Cleanup

Galvazin has 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.
