Product Technical bulletin

METAL BRITE HD   (RXSOL-16-1011-025) 

Product Description:-  A superior heavy duty and highly Concentrated liquid blend of surfactant & organic compound containing rust penetrating agent, solubilizer and inhibited phosphoric acid.

Field:- specially designed for removal of rust from any steel surface area and rust stain from Brass , Copper , S.S wood , ceramic and aluminium surfaces , painted or not . And act as surface brightner.

Procedure for Use:-RXSOL-16-1011-025 is highly concentrate

Dilute in water (always use plastic jar and RXSOL-16-1011-025 should be added to water never add water to RXSOL-16-1011-025.)

Surface should be sound clean and free from oil, grease, dirt etc.

Diluted materials apply on rusted area for 15 to 20 minutes then wash off with water repeat if necessary. (For stubborn rusted stains.)

Note:- For steel surfaces; remove oil, grease and old paint. Wet down entire surface with neat Metal Bright- Rx and allow to dry. Second wash may be necessary. Surface should have a grey/white appearance when the Metal Bright- Rx is dry. Steel surfaces will have a resistance to rust and will render a good base for paint. For removal of rust stains on painted surfaces and wood, Metal Bright Rx should be applied at full concentration for heavy stains, or diluted to 20-50% for light stains. Allow to soak for 15 to 30 minutes and wash off with water. A second application may be necessary to remove the stubborn stains.

Spraying Direction: – Using an empty / clean 210 liter drum, fill with 190 liter of fresh water and add 20 liters of Metal Bright Rx This makes a 10% solution, which can be sprayed onto areas in coated tanks where rust stains are showing and over actual rusted areas. Once spraying is completed, wait 20-30 minutes and fresh water rinse with lots of water, if possible use butterworth machines for a more efficient result. This method can be used in stainless tanks to “freshen up” the look of the stainless materials. Make sure to rinse the tank very well, as residual detergent within the Metal Bright Rx will show up in a Wall Wash.

Injection– Not suitable.

Re-circulation: – When hand spraying is inadequate (too much area to cover), prepare a 2% – 5% solution in the tank using fresh water, heat solution to 50o C, then circulate the solution through butterworth machines for 3 x 45 minutes drops minimum. When using fixed machine recirculate for a minimum of 3 cycles. Rinse out the tank using hot seawater 85o C for 2 hours making sure that there is no form remaining in the water at the pumpstack drain cock. After the hot wash, the tank must be rinsed with fresh water and dried.

* If the mixture is allowed to overheat, it will soften epoxy / phenolic coating. *

Use a strainer at the pumpstack when circulating any solution. Tank Lining – Stainless / Epoxy, Phenolic

Product label
In general terms and thumb rule for Metal Brite is MORE RUST required more Metal Brite. Chemically Rust { iron oxide (FeO) } is soluble in pH values below 4.0, . Thus, the oxide (oxygen) dissolves as it is formed instead of depositing on the metal’s surface. So it is clear more rust required more Metal Brite to get dissolve. In practical if the area is fully rusted corroded then direct Metal Brite can be used to dissolve rust particles, while in light contaminated part Metal Brite can be diluted in between 20 to 70% .

2nd factor is the time which is directly affecting the cleaning result. If base metal is aluminium then use Metal Brite concentration 10 to 30% for not more then 5 Minutes. For removal of rust stains on painted or iron surfaces, use 10–30% of Metal Brite soultion for 15–20 minutes. And for heavily rusted and corroded or soiled surfaces and tarnish on copper and brass, use a solution of 20–50%, for 15–40 minutes.

The 3rd important point always be noted, After cleaning of rust from Metal Brite all area should be fully rinsed and clean properly with fresh water. And for best long time result to keep rust free surface, Surface can be chemically neutralized with RXSOL-41-8896-025 ( dilution ration 1 Ltr RXSOL-41-8896-025 with 10 Ltr water ). The scientific reason behind that is As With the Rust oxide gone with Metal Brite, the metal surface is in direct contact with the acidic solution, and the corrosion reaction proceeds at a greater rate than it does at higher pH values. For increasing pH values greater than pH 10, the rusting rate seems to fall as pH is increased with help of RXSOL-41-8896-025.(http://www.rxmarine.com/Professional-Heavy-Duty-Alkaline-Cleaner)
