RUST GRIP® is a SSPC E.Crone Knoy Award winning, tough, one-part, single component, moisture-cure polyurethane coating, that absorbs atmospheric moisture to cure.
RUST GRIP® is loaded with a metallic pigment for strength and is also resistant to chemical solvents and acid splash. RUST GRIP® tensile surface tensile strength is 6,780 psi upon curing. (Concrete by comparison is appox. 4,000 psi). RUST GRIP® is used to remedy and prevent corrosion and it is also patented to remedy / encapsulate lead-based paints and other biohazards materials, including asbestos.
Rustgrip also has passed over 27 independent ASTM test, along with an impressive listing of national and international certifications. Rustgrip has exceeded over 15,000 hours of ASTM B117 salt fog corrosion with a perfect score (no corrosion ) and 10,000 hours ASTM D5894 cyclic salt fog , UV testing with a perfect score ( no corrosion). All ASTM testing has independently been done by accredited USA labs.
RUST GRIP® provides a protective coating film of superior adhesion and flexibility, and is resistant to abrasion and impact. RUST GRIP® can be used as a primer or as a one-coat all in one system . RUST GRIP® does not require UHP water-jetting or sandblasting to new or near new metal ( No SP5 0r Sp10 required) for surface preparation. RUST GRIP® can be applied completely over rusted surfaces and firmly bonded commercial paints. A light to medium surface rust is preferred before applying RUST GRIP® to metal surfaces. Flash rust on the metal surfaces allows RUST GRIP® to penetrate into the microscopic pores of the metal.
The reason RUST GRIP® does not require sandblasting or UHP water jetting to new or near new metal is because RUST GRIP® does not use glue for adhesion . RUST GRIP® is designed with propriety additives that allow it to penetrate into the pores of the metal or concrete. Once in the pores of the metal or concrete, RUST GRIP® uses moisture to chemically react, swell and bond with the metal surface, where it prevents air and moisture (the electrolyte) infiltration from the inner pores of the metal or concrete, to the outer surface, thus eliminating the necessary electrolyte component needed for corrosion development.
When compared to traditional three (3) coat corrosion systems, RUST GRIP® provides tremendous advantages in terms of prevention of corrosion long term, at the most competitive total price. Why do we say this? Well, as we all know, surface preparation is very important when remedying corrosion. The surface preparation for all competitive three coat corrosion coating solutions ( zinc primer, epoxy middle coat, and urethane top coat, require the removal of all surface corrosion from the surface of the metal, during surface preparation, to either new or near new metal level (SP5 or SP10). This is typically achieved by sandblasting or UHP water jetting, which is expensive, time consuming and environmentally unfriendly.
Additionally, all 3 coat corrosion coating systems use glue for adhesion. The problem with coatings that require the use glue for adhesion, particularly when the coating’s surface prep requirement is that of sandblasting or UHP water-jetting to new metal or near new metal (SP5, SP10), is that, it is almost impossible during the surface preparation phase, to create a finished metal surface that is truly free of flash rust and contaminants that are in the pores of the metal, and at times, even on the surface of the metal.
In most cases, even after sandblasting or UHP water jetting of the metal’s surface to new or near new metal (SP5 or SP10), before the zinc primer is even applied, the metal’s surface will start to immediate flash rust on the surface of the metal and in the microscopic pores of the metal. If you wait 20-30 minutes, you can visibly see corrosion redeveloping on the surface of the metal before the zinc primer (of the three coat system) is even applied.
Additionally, even after cleaning the metal’s surface of salt to an acceptable level, per the 3 coat coating system’s technical requirement, there is always salt contaminants still left in the pores of the metal.
Because of the difficulty in removing all the contaminants that are in the pores of the metal and the flash rust that reappears shortly after cleaning the metal’s surface to a SP5 or Sp10 level, contractors more often than not are forced to apply the zinc primer directly over the flash rust and contaminants that are in the metals pores.
What happens over time, when 3 coat systems are used, is that the flash rust that always develops on the metal’s surface and the contaminants in the pores of the metal, they will causes the glue, at some point, to give away and you eventually will have coating failure / corrosion development from the inside of the pores to the outer surface of the metal.
This (corrosion developing as a result of the glue giving away over time) does not happen when RUST GRIP® is used to remedy and prevent corrosion, as RUST GRIP® does not use glue for adhesion. Again, RUST GRIP® is formulated with proprietary additives that are designed to allow RUST GRIP® to penetrate into the microscopic pores of the metal, bond with the metal and then become one with the metal. After 21 days of fully curing, the surface tensile strength of RUST GRIP® increases to 12,000 psi, which is 3 times harder than concrete on the surface. So, the idea of a rust bleed through when RUST GRIP® is applied properly, is impossible. RUST GRIP® also has zero (0) permeability (meaning it does not breath), so when RUST GRIP® penetrates into the pores of the metal, bonds with the metal and become one with the metal, it removes the potential of corrosion development by eliminating the required electrolyte (moisture and air) that is need for corrosion to develop. RUST GRIP® does this from the inside pores of the metal, to the outer skin level of the metal, totally encapsulating the metals surface and de-voiding it of an electrolyte (air and moisture). No electrolyte, means no corrosion. If fact, the preferred surface profile, prior to applying RUST GRIP® to any metal surface, is to allow for a slight rust profile on the surface of the metal before applying RUST GRIP®. RUST GRIP® only require that loose mil-scale and pack rust be removed from the surface prior to applying RUST GRIP® so that Rustgrip is applied to a firmly bonded surface.
Rustgrip can be used to patch a hole in a tank or other metal surfaces by simply using Rustgrip and fiberglass mesh to make a steel like patch over the hole (See in video below). You can watch the videos on your smart phone as well, if not able to view the videos on your work computer).
Economically, RUST GRIP® offers tremendous advantages. It is well known that when remedying and preventing corrosion, $7 out of every $10 spent is for surface preparation ( sandblasting , UHP water-jetting) alone.Because RUST GRIP® does not need this level of surface preparation, it provides an immediate savings because it does not require clients to spend $7 of $10 for surface preparation. Rustgrip is typically a minimum of 70% cheaper than a 3-coat corrosion system when all is said and done, while providing better performance (No glue used for adhesion) and significantly faster turnarounds that also impact the financial bottom line. Additionally, the labor cost is 3 times more to apply 3 coatings (as with 3 coat systems) versus 1 coating as with Rustgrip or 2 coatings if our Enamogrip coating is included as part of the solution.
Surface rust is a disadvantage for competitive 3 coat 2 part corrosion systems, but it (rust on the surface) is an advantage for Rustgrip.
It is also important to mention another Rustgrip advantage over 3 coat corrosion coating systems that require sandblasting or UHP, when the goal is to remedy lead-based painted surfaces, asbestos and other bio-hazardous materials, is that, just as with corrosion, no containment or sandblasting to new metal is required for complete encapsulation of lead based painted and asbestos surfaces when Rustgrip is used. Rustgrip is Patented to remedy lead-based paint, corrosion and bio-hazardous material without sandblasting to new metal. Rustgrip has passed the USA federal required ASTM E1795 test for remedy of lead-based paint without sandblasting. Many of the characteristics that are necessary for encapsulation of lead based paint and bio-hazardous material are also useful in preventing and remedy of corrosion. When Rustgrip locks down a surface that has bio hazardous material on the surface, it prevents anything from going out or in, which is another reason that no glue is used. When Rustgrip is used, the surface is devoid of moisture and air, which means there is no electrolyte. No electrolyte means no corrosion.
Ideal for Metal and Concrete applications.
