CORROCOAT’S SUCCESS IS BACKED BY 40 YEARS OF OWN RESEARCH & DEVELOPMENT
Corrocoat is driven by own research and development. The “CORROCOAT” solution has evolved into a specialized package comprising design, engineering, manu-facture and testing, all of which are comprehensively structured to meet the exacting demands of industry. Our Corrosion Prevention service technology coating systems, coupled with the use of skilled engineering techniques are backed up by advanced levels of technical expertise.
WHAT DIFFERENTIATES CORROCOAT’S MATERIALS FROM OTHER COATINGS?
Apart from Chemical Resistance, the most important characteristic for coating life expectancy is the coating’s resistance to moisture vapour permeation. The time for small molecules, such as oxygen or water to diffuse through a barrier film, can be measured and quantified allowing a direct comparison between different types of coating.
Corrocoat materials contain multiple layers of micro flakes of glass, bound together with high performance resins. The resins are solvent free, 100% solids polymers. Many different types of flake glass filler exist. The thickness of the flakes, quality of flakes, quantity of flakes and number of layers of flake will affect the permeation resistance and subsequent long-term life expectancy of the coating. Other factors such as the packing density of flake and optimum flake loading levels also influence the rate of moisture vapour transmission. The flakes are relatively impermeable and create a long tortuous winding path for small molecules to follow when they pass through the coating to the steel. The longer the winding path length, the longer the time to permeate the coating and the longer the life expectancy.
