Corrosion protection for steel and iron no longer requires the logistical burden of hot-dip galvanizing. SK Formulations introduces G-COAT , an advanced cold galvanizing coating system.
Impregnated with high-purity zinc and crafted using our proprietary Grafted Copolymer technology , G-COAT provides robust, sacrificial protection against rust and oxidation.
Whether you are performing field repairs on existing structures or looking for a high-performance zinc rich coating for new projects, G-COAT delivers a viable, cost-effective substitute for traditional galvanizing methods.
The G-COAT Advantage: Sacrificial Zinc Protection
G-COAT works through cathodic protection. The zinc in the coating acts as a "sacrificial anode," corroding in place of the steel substrate. This ensures that even if the coating is scratched, the underlying metal remains protected from the environment.
- Single-Pack, Ready-to-Use : No complex mixing of zinc dust and binders; simply stir and apply via brush or spray.
- Rapid 30-Minute Drying : Touch-dry at room temperature in just 30 minutes , allowing for fast project turnaround.
- Self-Priming Performance : Formulated for direct application to iron and steel surfaces without the need for a separate primer.
- Ease of Rectification : The ideal solution for touch-ups and field repairs where hot-dip galvanizing is not feasible.
- Elite Corrosion Resistance : Provides a long-lasting barrier against salt, moisture, and industrial pollutants.
- Exceptional Weathering & Aging : Unlike standard zinc paints, G-COAT features excellent aging resistance , maintaining its integrity for years.
- UV & Outdoor Stability : Engineered for outdoor exposure; it will not chalk or degrade under intense sunlight.
- Abrasion & Fatigue Endurance : Excellent flexibility and scratch resistance, making it suitable for structures subject to mechanical vibration or movement.
Our cold galva coatings are trusted across critical infrastructure sectors:
- Renewable Energy : Protection for solar structures , mounting rails, and tracker systems.
- Energy Sector : Infrastructure in Oil & Gas industries , refineries, and offshore platforms.
- Transportation : Railway bridges , gantries, and structural steel for transit systems.
- Power Distribution : Electrical transmission towers and substation structures.
- Heavy Engineering : Industrial machinery, MS structures, and OEM equipment.
Frequently Asked Questions (FAQ)
While hot-dip galvanizing involves dipping metal into molten zinc G-COAT cold galvanizing provides a similar level of sacrificial protection through a high-concentration zinc-rich film. It is the preferred choice for large structures that cannot be dipped and for repairing damaged galvanized surfaces.
Yes. G-COAT is a high-performance, weather-resistant system that can be used as a standalone protective layer. It is also an excellent zinc rich primer if you intend to apply a decorative topcoat later.
For the best results, the steel or iron surface should be clean, dry, and free of loose rust, oil, and old paint. Because G-COAT is self-priming , it bonds exceptionally well to properly prepared metal surfaces.
