TRIPHOS-C

TRIPHOS-C (Class-C) is a Liquid Degreasing, Derusting, and Brush-type Phosphating Chemical suitable for removing Rust, Oil and producing a lightweight phosphate coating on Iron and Steel Surfaces. The coating conforms to Class C/D of IS: 3618, 1966, and the coating weight ranges from 1.1 to 4.3 gms/m² depending upon the concentration used for application. It is ideally suitable for large structural works such as Rail Coaches and Bus Bodies etc.

CONCENTRATION : 30 to 50% by volume as received, depending on the degree of rust/oil present on the surface, average 1:2.

 

METHOD : By brushing/swabbing.

 

APPLICATION : Apply the solution to the metal surface and swab or brush thoroughly to remove rust/oil. Allow the chemical reaction to proceed to air-drying. Then wipe with a wet rag and then with a dry cloth. Once the film is dry, further operation such as Primer/Paint application can be carried out.

 

TESTING :

FREE ACID : Take 10ml of 1:2 bath solution and titrate vs 1 normality Sodium Hydroxide using Bromophenol Blue Indicator. Titration value should be 10 to 15ml, when the color changes from yellow to blue.
