BRIEF DESCRIPTION
APPLICATION
Inorganic Zinc Silicate is a water-based, fast drying, high zinc content anti-corrosion coating developed by NASA (see NASA Article) and is used in harsh environments, primarily on exterior steel surfaces exposed to marine atmosphere, high humidity, sea water and weather. It should be noted that in the 80s this product had been commercially promoted as IC-531; however, it has been enhanced over the years and is no longer marketed under that name.

It performs well in demanding pH range 5-9 corrosion environments. It acts as a moisture barrier and self heals to continue protection when damaged. It provides cathodic sacrificial protection and thus prevents corrosion of the underlying steel, like galvanizing. It contains 90% zinc by weight in the dried film.

CTI has been at the forefront in the application of this galvanized replacement coating. It is comparable to federal Department of Defense specification DoD-P-24648 and meets Class B requirements for Slip Coefficient and Creep Resistance, 0.69. This is an environmentally friendly, water based coating that contains 0 VOC (Volatile Organic Compounds) and no flash point. There are two prevailing classifications with regard to protective coatings - barrier coatings and sacrificial coatings. Inorganic zinc silicate is a sacrificial coating and can be over-coated. Coating thicknesses can be reasonably controlled for maximum design flexibility.

Industrial-Utility, marine, military, transportation (railroad, bridge, highway) parts and structures. These industries have utilized CTI's expertise and application services, particularly when steel is exposed to salt spray corrosion. This coating outperforms galvanized coatings in highly corrosive wet/dry/wet environments.

In process environments, inorganic zinc typically is used as a one coat system for fresh and salt water immersion or as a primer for harsh corrosive environments. Use where abrasion resistance and hardness are required. Acts as an economical substitute for galvanizing. Ideal for bridges, tanks and structural steel. The coating has a high performance to cost ratio. As a result, industries are experiencing significant cost savings in terms of labor and maintenance reductions in the replacement and repair of corroded parts.
