NanoPrime How It Works Printable File

WHAT IT IS AND HOW IT WORKS

• NanoPrime is a single pack, water based, primer that uses phosphoric acid (PH 3.5) as its main reactive agent, in an acrylic polymer matrix. Nanoprime is assisted by nanotechnology, which helps the reaction continue long enough to create a meaningful layer of protective, insoluble, phosphates. The Nanoprime polymer matrix is all composed of very fine, micro scale particles.
• NanoPrime is environment friendly, ultra-low VOC and non-toxic.
• NanoPrime is a single product that is universally effective for practically all substrates. This eliminates the need for the large number of different primers currently required and offered by all major suppliers. This fact greatly reduces costs, complexity and chances of failure.
• NanoPrime requires minimal surface preparation and can be applied directly over oxidized surfaces and old paint that still has good adhesion.
• About 75% of paint failures are due to issues with surface preparation. Nanoprime not only reduces costs by eliminating the need for extensive surface preparation, but it also prevents most paint system failures due to its low surface requirements and insensitivity to chlorides.

ABOUT CHLORIDES AND WHY NANOPRIME IS INSENSITIVE TO THEM

The presence of chlorides, even in very small amounts, is one of the main mechanisms of paint system failures.

The phosphoric acid in the Nanoprime matrix dissolves and neutralizes salts and contaminants. Then, the acid chemically reacts with the metal substrate to form impermeable phosphates that provide protection from further attack.

Iron Phosphate, Aluminum Phosphate and Zinc Phosphate are insoluble salts that provide excellent bonding and adhesion to the substrate, as well as excellent corrosion protection.

NANOPRIME ON STEEL

The reaction of phosphoric acid in Nanoprime and Iron Oxide Fe2O3 produces Iron Phosphate Fe(PO4)2.

The reaction of phosphoric acid in Nanoprime and Iron (Fe) produces a different form of Iron Phosphate Fe(PO4)2.

In general, a layer of steel that is has a clean surface that is free of oils and loose dirt that has light rust (Iron Oxide) is the ideal substrate for Nanoprime as it results in a thicker layer of Iron Phosphate. Once the oxide is consumed by the phosphoric acid in Nanoprime, that acid then reacts with the underlying base steel to provide excellent adhesion and corrosion protection.

NANOPRIME ON ALUMINUM

The reaction between Aluminum or Aluminum Oxide with the phosphoric acid in Nanoprime produces Aluminum Phosphate AlPO4, that is a very stable, insoluble crystalline solid, providing extremely good corrosion protection with excellent adhesion to the base metal.

To the best of our knowledge, Nanoprime is the only primer that produces a chemical bond with Aluminum and does not require any surface preparation or "profiling," other than a water wash to remove oils and dirt.

NANOPRIME ON GALVANIZED STEEL

The reaction of the phosphoric acid in Nanoprime with Zinc or Zinc Oxide results in Zinc Phosphate Zn3(PO4)2 that has extremely good corrosion protection. With Nanoprime, the Zinc Phosphate layer is chemically bonded to the substrate, offering excellent adhesion and protection.

Based on tests, Nanoprime extends the life to any galvanized structure by a factor of 3 to 5.

Nanoprime is a solution to corroding galvanized structures that no other product can offer. It does this by reacting with both the corroding steel and the remaining galvanized structure.

NANOPRIME ON EXISTING PAINTED STEEL

Typical paints including epoxies and polyurethanes are alkaline. The phosphoric acid in Nanoprime chemically reacts with those paints to form a bond to the surface.

After high pressure washing, existing paint that remains is assumed to be sufficiently bonded to the substrate. The phosphoric acid in Nanoprime will react with both corrosion and the remaining paint. Any rust will be converted to corrosion resistant Iron Phosphate and Nanoprime will chemically bond to the remaining paint. This provides a low-cost tool for preserving existing structures where the existing paint system is starting to fail. This feature of Nanoprime prevents having to sandblast the entire structure down to the base metal.

NANOPRIME ON CONCRETE

The phosphoric acid in Nanoprime reacts with the alkaline calcium compounds in the concrete, to form Calcium Phosphate and other byproducts. The fine grain nature of Nanoprime helps it get absorbed in the concrete.

Calcium Phosphate Ca(PO4)2 is an insoluble salt which, along with the polymer matrix of Nanoprime, seals the concrete to protect it from further penetration of water and chlorides and other contaminants.
