Superior Products International II Inc. Certified Coating

Rust Grip® was specifically developed in the field to stand up against the harshest environments demonstrating excellent performance and a paradigm shift in corrosion coatings technology. It 100% covers any rusted area to stop corrosion in it tracks and is rated to 6,780 psi (478 bar) surface tensile strength.  

Rust Grip® is a tough, one-part, moisture-cure polyurethane coating that absorbs atmospheric moisture to cure. It is patented and loaded with unique aluminium pigments (not zinc) for strength and is also resistant to chemical solvents and acid splash. 

As a solvent, Rust Grip® completely fills the pits, cracks and pores of the metal substrate unlike a surface topical glue coatings, then using the atmosphere anchors in, cures, seals and encapsulates against any possibility of outside air, moisture or minerals from entering the pores and attacking the surface and causing further corrosion or penetration of any kind to a permeability rating of just 0.24. 

Rust Grip® is tested to encapsulate:

Rust Grip® may be applied to metal, concrete, fibreglass or wood and is extremely easy to use, fast and labor saving. Upon curing, Rust Grip® provides a very, very tough protective coating of superior adhesion and flexibility, and is resistant to abrasion and impact and can be used as a primer or as a one-coating system and is patented to encapsulate lead-based paints, asbestos and bio-hazards. It can be applied over pressure-washed, completely dry flash rust and firmly bonded commercial paints. In most cases, a white or near-white blasting is not required. A light to medium surface rust is preferred as the profile. 

Rust Grip’s coating premium advantages are:

  • One-Coat System
  • Limited Surface Preparation
  • Encapsulation
  • High Surface Tensile Strength

Rust Grip® offers a simple solution for true encapsulation. A one-coat system that can be applied over a variety of surfaces that meets or exceeds stringent registrations, certifications and testing is truly a paradigm shift that lasts over 20 years. We know you’ll love the results!

Rust Grip® Rated No. 1 by the Society of Petroleum Engineers

A long-term lab and field study by Chevron and Workstrings International published by the Society of Petroleum Engineers, tested 18 different coatings on drill pipes for eight years. Drill pipes are the toughest environment anyone can ever imagine and Rust Grip® was the top performer. In that paper they highlight the cascading benefits that came from solving the corrosion problem. You solve the corrosion problem, that’s already millions of dollars in savings and then because you’re not having to swap out these drill pipes so often, you’re saving millions in logistics.

“Beyond the goal of eliminating corrosion and pitting-related damages, the introduction of externally coated completion tubulars has facilitated a paradigm shift in the way operators manage rental completion tubulars.”

“This coating system provides a trouble free solution and significant cost savings to the operator and pipe rental company through reduction in pipe repairs and damages; loss of capital assets; and rig time due to pipe issues, fluid issues and corrosion issues.”

“The savings realized in connection repairs alone is estimated to exceed $250,000 per well.”

Rust Grip® Encapsulates Lead-Based Paint, Asbestos and Corrosion

Numerous steel structures such as water tanks, bridges, aircraft hangars, antennas, ladders, poles, railings, catwalks, fire hydrants, fuel storage tanks, and metal buildings were constructed or installed with lead-based coatings. The removal of lead-based paint from steel structures is currently accomplished through a variety of methods, the most common being abrasive blasting.

Prior to recoating steel structures, abrasive blasting is required in order to remove the old lead-based paint and to provide adequate surface profile for bonding the new paint to the substrate. During abrasive blasting, a tight containment structure is required to prevent lead dust from contaminating air, soil or water. Inside such containment structures, increased worker protection is required due to high lead dust concentrations. The large, concentrated volume of waste generated by abrasive blasting is hazardous and requires additional stabilization treatment prior to disposal. RUST GRIP® eliminates sandblasting. Read More >

Rust Grip® provides protection against conditions where the surface cannot be sandblasted or worked upon extensively. It is a replacement to 3 in 1 coating systems and challenging the standard practices as a much more robust solution so clients can focus on pivotal issues rather than worrying about their assets degradation.

15,000 hours (=30 Years) Salt Fog Test for Rust Grip®

SPI Coatings coated some plates with HPC on it at 12.5mm or 500 mils. This was over-coated with Rust Grip® to seal and prevent water and air from getting to the HPC.

They placed these plates inside a salt-spray cabinet for the ASTM B117 testing to see how well the Rust Grip® would protect the HPC from salt spray and UV cycles.

It has been 15,000 hours and they look like the first day placed inside the cabinet.

The HPC would be both protected and there’d be zero corrosion on any pipes underneath which could manage 500-550°C internal temperatures. This is a great solution to reduce any threat of corrosion under insulation that most companies have using fibreglass jackets etc. See the Report pdf

Rust Grip® vs Surface Coating and Galvanized Metal

With solvent carriers that allow it to penetrate deep into the pores of surfaces, Rust Grip® outperforms typical surface coatings. Traditional coatings adhere to roughness on the surface layers and are susceptible to wearing over time. Oxidation and acid rain can enter and begin corrosion, even though the surface coating remains intact.

After it penetrates, Rust Grip® draws moisture from the atmosphere which reacts with the active ingredients of the base component. This results in a gassing effect of the molecules and expands them swelling into all the pores to block out air, gasses, and moisture and to encapsulate the surface.  The surface cannot breathe, cannot get moisture, and cannot oxidize again.

When other corrosion coatings are applied to surfaces after a completed white metal blast, corrosion redevelops after only 6 months to 2 years under the coating film, causing bubbles on the surface from the corrosion off-gassing.

Galvanized metal and re-galvanized metal has been hot pressure treated with zinc oils. Galvanization doesn’t anchor itself inside the pores, but stays on the surface. Therefore, galvanized metal lacks the strength and durability of Rust Grip® and can start to re-corrode in as little as 2 years. In hot climates (as per US Government Reports), the galvanized metal will crack, peel and deteriorate quickly and over long spans it can also warp or buckle beams.

A surface coated with Rust Grip® is strong and resilient. It is a durable coating that offers long life in extreme conditions, outperforming galvanized surfaces. It’s designed to last over 20 years or more in the toughest environments without a topcoat (source).

Rust Grip® on Fibreglass

You can use Rust Grip® on fibreglass if the surface has porosity. If no pores for the Rust Grip® to penetrate down into, then no way for it to anchor and lock down. You can ‘roughen’ up fibreglass to create pores for penetration.

Rust Grip® and Chemicals

Rust Grip® has been tested against 1,500 different chemicals and is only unsuitable for continuous immersion in ammonia and urea derivates.

Concrete Gas Encapsulation

Rust Grip® tested and patented to seal off biohazards by incapsulating the surface and sealing it down to to a permeability of 0.24 perms. Anything less than 1.0 cannot breathe air, moisture and most gases. With the issue of Radon gases for example, 3 coats should lock it down.

Mould and Mildew

Rust Grip® has the ability to protect against mould and mildew on surfaces that are prone to damage from prolonged exposure. Rust Grip® creates an unsurpassed protective surface, proven time and again through onsite evaluations and real-world applications.

You would need to treat the surface with either bleach or 10-15% hydrogen peroxide to kill the mould then topcoat with 100-150 micron DFT of Rust Grip®. Rust Grip® has a permeability of 0.24 perms. That means it has no porosity. In the ASTM E 1795 liquid encapsulation test there are about 20 tests needed to pass to be considered an encapsulation coating. That’s where the 0.24 perms comes from.

The ASTM E 1795 test verifies Rust Grip® ability to encapsulate lead based paint. If there is paint and is flaking you will need to scrap off the loose bits as Rust Grip® may not be able to compress it then encapsulate. The encapsulation is based on the paint that is adhering to the surface.

What’s the difference between Rust Grip® and a rust converter?

Rust Grip® works by penetrating through and rust, encapsulating it and preventing further expansion.  Rust converters work by chemically changing the rust into a benign form which only lasts for a few months and must be overcoated (source).

Surfaces can Rust Grip® be applied to

RUST GRIP® can be applied to aged or new steel or aluminium, concrete, wood, and rusty or corroded steel and aluminium

Times are estimates of how long it will take Rust Grip® to enter the overcoat window when the next coat may be applied. The definitive test for when Rust Grip® may be over coated remains the “touch” test when the coating may be touched with no colour transfer, and no damage with thumbnail.

Important

Stir product thoroughly before using. Avoid a vortex when stirring to draw in moisture. Rust Grip® can be applied by brush, roller or spray equipment. It should be applied evenly without buildup to 200-300 microns DFT.

Rust Grip® should be immediately cleaned after it is applied. There is no way to remove Rust Grip® when it has set. Brushes and rollers must be thrown away. Flush spray machine, hoses and gun with solvents to clean out. When breaking for lunch, seal off Rust Grip® container (tip: separate lid from tin with heavy duty plastic bag). Use caution when resealing the container, as any Rust Grip® on the seal track of the lid or container may cause the two surfaces to permanently seal.

Because Rust Grip® works rapidly, do not leave a container open to the air for longer than 4 hours, or Rust Grip® will draw in the ambient humidity and begin to cure. A brush or roller used to apply Rust Grip® cannot be cleaned.

SOLVENT: Clean-up or reduction, use MEK, Xylene or MIBK. If sprayed, keep solvent ready to clean equipment before breaks (lunch hour) or at conclusion of job. Run solvent through the machine and hoses and leave gun submerged in solvent pail. *CLEAN IMMEDIATELY OR WILL RUIN EQUIPMENT.

When storing Rust Grip® as it’s moisture cured use Nitrogen gas to expel oxygen in the tin to reduce chances of the coating from curing.

Cautions and Warning

CAUTION: Wear gloves and protective clothing. Extremely tough to clean off skin. Wear eye protection and mask.

Do not take internally. Avoid contact with eyes. If solution does come in contact with eyes, flush immediately with water and contact a physician for medical attention. Avoid prolonged contact with skin or breathing of spray mist. KEEP OUT OF REACH OF CHILDREN. This is a flammable liquid. Keep away from flame or fire or other sources of ignition.

Practice standard safety precautions when working with Rust Grip®, including protective clothing. Rust Grip® will adhere to and cure on skin. Rust Grip® is USDA-approved, but it will wear on skin for several weeks before being sloughed off with normal skin renewal.
