Product information
ROCOL Metal Enriched Paints have a Triple Protection formula, which has been developed by ROCOL scientists to exploit the chemical properties of Zinc and an advanced resin system to shield steel from corrosion.
Excellent corrosion protection. This heavy duty cold galvanising spray can be used to repair the surface of galvanised components that have been damaged or removed due to welding or other mechanical operations.
The differences between standard paints and ROCOL Metal Enriched Paints are significant.
Standard paints create a passive barrier, which when breached will offer no protection against corrosion. Rust will begin to form underneath the paint, quickly removing it from the surface.
What is Triple Protection?
1. OPTIMUM CATHODIC DEFENCE
In order to protect steel from rust, Zinc can be engineered to sacrifice
itself; oxidising in place of the steel which it is protecting. Galvanisation
performance is determined by the purity of the Zinc and its concentration
in the formula. ROCOL uses high purity Zinc at concentrations of up to 95% in
order to maximise performance. ROCOL COLD GALVANISING Spray continues to
protect metal surfaces even when scratched* through the action of an invisible shield called a galvanic cell which covers
the damaged area.
2, ENHANCED WATER RESISTANCE
Unprotected steel surfaces are prone to the pooling of water, which if left, will cause corrosion within hours. This pooling
is due to microscopic pits on the metal surface which trap water droplets, this accelerates the rate of corrosion.
ROCOL metal enriched paints fill the pits, smoothing the surface, allowing the water to run-off more easily.
3. MECHANICAL TOUGHNESS
The binder within a metal enriched paint determines the strength of adhesion to steel. ROCOL metal enriched paints have
an advanced resin system which increases their durability and resilience to abrasion, therefore providing an exceptional
protection life time.
