Passivation for stainless steel | Reba Scientific

Passivation of stainless steel has conventionally been accomplished by immersing the steel in a nitric acid bath. This process is both hazardous and environmentally unfriendly.

Now, CitriSurf® citric acid passivation technology has proven to be a vast improvement over the traditional toxic nitric acid formulations.

Learn More about Passivation for Stainless Steel

Using citric acid in the passivation of stainless steel might sound like a new concept, however, it was developed years ago in Germany’s beverage industry, where they needed metal containers that were free of iron on the surface.

Not only that, Citric acid is organic, safe and easy to use. When formulated correctly, citric acid provides excellent performance at considerable cost savings. This acid is the same acid found in oranges and other citrus fruits.

What’s more, stainless steel isn’t the only metal that can undergo passivation with citric acid; it can also serve in the passivation of titanium and others.

Some argue that citric acid isn’t as effective as nitric acid. However, according to a 2011 study sponsored by NASA via the United Space Alliance, LLC, “citric acid most likely performs as well or better than nitric acid.”

A safer, more powerful alternative

BlowOut is a most aggressive line cleaner and descaler, yet non toxic and non corrosive. The potency of BlowOut combined, with its unique safety profile, makes it the natural choice of the U.S. Navy and U.S. Coast Guard. Further, Blow Out removes no trace metals from the system, making it legal to dispose effluent water directly into the sanitary system. Blowout is non-fuming, non-corrosive, non-toxic and biodegradable.

Blowout is the only non-acid solution that the Navy has cleared as their ships’ heat exchanger descaler! It is not just a non-toxic descaler, it is also a non-corrosive descaler with properties that keep your staffs and the environment safe.

Solvent free Degreaser

Unlike others, SC-1000 plant-based degreaser is non-toxic, Solvents free, biodegradable, Non-Flammable, Non-carcinogenic and contains no terpenes, glycol ethers, petroleum distillates, caustic or acidic additives.

Solvent free Degreaser

Unlike others, SC-1000 plant-based degreaser is non-toxic, Solvents free, biodegradable, Non-Flammable, Non-carcinogenic and contains no terpenes, glycol ethers, petroleum distillates, caustic or acidic additives.

This all-purpose plant-based cleaner cleans the grease from vehicles, industrial spaces, kitchens and building exteriors and can be used on ANY surface that is compatible with water. It effectively removes fats, oils, proteins, sugars and other organic refuse, inhibiting the growth of bacteria and fungus, making it a great food degreaser as well as a biodegradable cleaner.

SC-1000 is an affordable option with various dilutions available for heavy-duty and all-purpose cleaning, as well as cleaning glass and acrylic. Its level of concentration makes it strong enough to substitute eight different all-purpose cleaners. It reduce life cycle cost, provide better asset protection, aid compliance to ISO 14000 and ISO 18000.

non-toxic Cleaner and Degreaser

SynClean HD is a powerful water-based cleaner and solvent-free degreaser , patented ingredient and safely lifts grease from any surface without the use of solvents. Non-emulsifying, safe for any surface, SynClean is so safe it is endorsed by truck giants Volvo and Mack to safely clean big rigs. Also, it degrades hydrocarbons as well as animal and vegetable fats.

Non-emulsifying, safe for any surface, SynClean is so safe it is endorsed by truck giants Volvo and Mack to safely clean big rigs. Also, it degrades hydrocarbons as well as animal and vegetable fats.

Synthetic acid in SynClean essentially replace those toxic and hazardous Muriatic (HCl), replace Sulphuric, Phosphoric Acid, Urea Sulphuric, Polymaleic Acid and nasty solvents like Methylene Chloride, perchloroethylene, d-Limonene, NMP, Acetone, MEK, MPK, Alcohols such as Ethanol and IPA, Toluene (thinners).

Instead of using solvents, it grabs hold of hydrocarbon molecules and lifts them out of the material being cleaned. Since it takes the entire hydrocarbon molecules, it doesn’t absorb water or become weighted down at the bottom of containment units.

In addition to its extraordinary degreasing powers, it contains detergents, penetrants, and rust and corrosion inhibitors, for a powerful all-in-one system. It is ideal as a non-corrosive truck wash or for use on trains, buses and as a safe mining equipment wash.

Acid free Truck Wash

For years, the over-the-road truck industry has turned to acid washes to remove heavy build up and grime on its trucks. Of course, these products can streak the truck’s surface, etch the glass and dull the aluminium wheels and chrome.

Now, Torque! an acid-free truck wash & wax provide clean, anti-stick, protective carnauba wax in single application. Torque Super Duty Truck Wash & Wax combines the finest cleaners degreasers, brighteners and protectants, along with the right amount of our patented SynTech®, the world’s only synthetic acid, to offer the finest over road–truck wash available.

In fact, it’s the only truck wash guaranteed by Mack, Volvo, and Oshkosh trucks to not void your rust and corrosion warranty. This innovative 100% acid-free cleaner has a triple-zero HMIS score, is classified by OSHA as skin-safe and is non-D.O.T. regulated.

Other benefits of Torque include that it:

Are you battling zinc residue after galvanising?

That’s because the Hot Dip Galvanising industry often uses tape, silicone and lime for their galvanising procedures.

Finally, there’s a solution to this problem: Galvastop®. It is an easy-to-use paint-on masking product for Hot Dip Galvanising that goes through all pre-treatments and comes out of the kettle as an ash that is simply wire brushed off. Unwanted zinc sticks to the Galvastop® and not the steel, allowing you to easily remove both. No grinding or retapping required.

Chemical engineers developed this product as a stable and convenient stop-off
galvanising material. It’s also safe for use as a heavy-duty corrosion preventative
coating in extreme environments.

The benefits of Galvastop® include:

Non-hazardous polish - Mirror Shine

Polishing copper often involves hazardous industrial cleaning chemicals that put your health at risk. It can even grind down good copper metal, weakening your systems and requiring more frequent repairs!

Reba safe copper polish is the answer to heavily tarnished copper containers, fixtures and machinery. After removing any rust and contaminant with our other non- toxic cleaner, you can bring back its original lustre with just a single mirror shine polish.

Non-toxic quenchant

Induction hardening has never been easier or safer than with Aquatensid BW, the water-based quenchant. Aquatensid BW comes as a thick green liquid that offers non-toxic quenching and doesn’t contain mineral oil, nitrite or other harmful materials commonly found in chemicals used in induction hardening and tank quenching.

Aquatensid BW comes as a thick green liquid that offers non-toxic quenching and doesn’t contain mineral oil, nitrite or other harmful materials commonly found in chemicals used in induction hardening and tank quenching.

Aquatensid BW works because it has a short vapour phase, providing the fast and uniform quenching required by plain carbon and low alloyed steels. It also comes in a high concentration, reducing the quenching speed of water and avoiding any potential for distorting and cracking that can happen to particularly hard alloyed steels.

High lubricating properties and high film strength
