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. Galvacote, 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. Galvacote is infused with 99% pure and very fine zinc particles.
GalvaCote 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, rust and other contaminants. When used as a primer, GalvaCote can be topcoated with commonly available water based acrylic and urethane paints. It is important to allow the primer coat to dry completely before commencing with the application of additional coats or the topcoat.
GalvaCote has no fumes, odors or other hazards associated with the use of GalvaCote. All normal precautions for use, storage and handling should be excercised as with any other paint product. Work area, tools, spills, etc. can be easily rinsed with fresh, clean water. When applying DTM400 via spraying, make sure to protect surrounding areas from overspray. Wipe off excess and run-offs immediately with a damp rag or sponge. GalvaCote is also avilable in other metalic finishes on a special order basis.
