“Steel Guard Nanocoat™” – A Replacement for the Phospating Process :

“Steel Guard Nanocoat™” Antirust compound can replace the tedious 7 (Seven) stage Phospating Process and we only need to follow the below mentioned steps to make the applied surface Corrosion free & stronger adherence to the finish coat.

 
Cleaning / Degreasing of the surface
Sand Blasting (If Required)
Steel Guard “nanocoat” chemical treatment
Dry off (At room temperature)
Final painting with Enamel / Epoxy etc (If. Required)

Steel Guard “nanocoat” Treatment

Remarks

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.
Phospated material gets corroded within 8 hrs when subjected to Salt Spray Test Steel Guard coated materials won’t get corroded even till
48 hrs when subjected to Salt Spray Test.
Steel Guard is much superior in terms of protection against corrosion.
Dry film thickness of Phospate coating can go upto 50 microns Dry film thickness of Steel Guard
coating goes only upto 5 microns
Steel guard coated material is superior as it shows least possible
change in the dimensions of the applied surface
Phospate coating norms are not laid down by the Pollution Control Dept. Steel Guard is an RoHS complied
coating and comes under the Pollution norms.
Steel Guard is an eco friendly product
Information about non inflammability not available. Steel Guard is non inflammable.

 

Steel Guard gives protection against fire hazards.

Phospating is a tedious, time consuming, labour intensive job involving large amount of money & labour.

Steel Guard coating is a short easy, simple coating job involving a very small amount of money & labour. Steel Guard is much more economical and less time consuming.
 

Cross Cut Test :

To check the Adhesion of any paint & primer with the substrate of the surface to be painted, Cross Cut Test (ASTM D 3359) is to be conducted to check the adhesion & bonding of the paint with the surface.

 

The mentioned picture explains the entire Cross Cut Test process wherein cuts are made (Both Horizontally & Vertically) with the help of a blade and then with the help of sticky plastic papers & cellotapes the cross cutted portions are peeled off.

The results can be evaluated in terms of the nos. of squares which adhere to the paint. If the nos. of squares attached to the plastic paper is high, the adhension is said to be poor and if the nos. of squares attached to the plastic paper is less, the adhesion of the paint with the substrate is said to be higher & good.

 
 

The results of the above Cross Cut Test need to be classified on the basis of the below mentioned 5 categories which are as follows:

 
 
Cross Cut Test conducted on Normal Phosphate Coating :
 
 
Cross Cut Test conducted on Steel Guard “nanocoat” Coating :
 
 

The above mentioned results clearly state a much better performance of Steel Guard coated surface as compared to normal Phospating process and we can safely conclude that Peeling of the paint from the substrate will be reduced drastically , which will thus lead to a much higher corrosion resistance over a long period of time.
