Comparative Performance Evaluation of Steel Guard “nanocoat” with Phospate Treatment of Iron & Steel for protection against Corrosion.

Phospating Treatment

Steel Guard “nanocoat” Treatment


Phospating process is classified in 5 (Five) classes i.e. Class A1 (Heavy Weight) , Class A2 (Heavy Weight) , Class B (Medium Weight) , Class C (Light Weight) , Class D (Extra Light Weight) as per IS : 3618 - 1966 in accordance to the nature of protection required.

Steel Guard is single handedly capable of taking care of all the types of protection provided by the different phospating processes.

Steel Guard is a superior because as a single product, it can take care of multiple aspects.

The process consists of 5 (Five) stages i.e. Surface Preparation, Phospate Treatment, Rinsing , Drying and Sealing

The process essentially consists of 3 (Three) stages i.e. Surface Preparation, Steel Guard treatment and drying. Sealing with organic coatings are required only for extreme heavy duty corrosion protection purposes.

Steel Guard is an economical and time saving product as the process requires a lesser number of stages.

The strength of the phospating solution, measured as Pointage is to be checked periodically and the repleshiment is to be done accordingly.

No checking of the strength of the Steel Guard solution is required and it is suitable for repeated use without any replacement due to the lack of strength.

Steel Guard is superior since it highly economical and very less supervision is required.

After phospating , the organic sealing by paint , varnish or lacquer is to be done immediately. If an interval is unavoidable between the first stages of sealing, the phospated components shall be stored under conditions that
preclude contamination & condensation of the moisture on the surface. The above stipulation is under IS : 3618 -1966 , clause 4.6.

After Steel Guard treatment, no organic sealing is immediately required. The coated material can be left without any organic coating under any atmospheric
condition week after week.

Steel Guard is much superior in terms of protection against corrosion.

Heating arrangments are required for phospating.

No heating arrangements are required whatsoever.

Steel Guard is much more economical and less time consuming.

Phospated material gets corroded within 24 hours without sealing.

Steel Guard coated material shows no sign of corrosion even after 15 days.

Steel Guard is much superior in terms of protection against corrosion.
