Dry Coat Rust Preventative is a water-based rust preventative liquid for ferrous metals (such as steel and iron). It is easily applied using spray or dip and upon drying Dry Coat leaves a clear, protective coating that protects against rust and corrosion. Dry Coat will dry-to-touch within 30 minutes at ambient condition and it does not attract dirt or dust on metal parts such as other sticky or tacky products. It is non-hazardous and easily washes off using mild detergents or common metal cleaning solutions. Dry Coat is safe to use on stainless steel and chrome and will not harm most elastomers or plastics. Dry Coat protects for up to one year for items stored indoors.

Dry Coat prevents rust from forming on ferrous metals in two ways.

1. Once Dry Coat is physically applied, it adheres to the surface of the metal leaving a protective film. Upon drying, Dry Coat forms a hydrophobic layer that provides a barrier to water and other rust-causing substances.

2. One component of the Dry Coat formula is Vapor Corrosion Inhibitors (VCI), a class of rust-preventing compounds that release molecules from the compound into the air. The VCI molecules attach themselves to the metal’s surface to form an invisible, thin film that works to protect metal from rust. If metal parts are kept enclosed during storage (e.g. using a bag, box, storage tub), the VCI vapor is kept contained and able to attach to any non-coated metal surface.

- A superb and safe water-based rust preventative

- Dries to the touch – no sticky, messy liquids to clean up

- Keeps metal parts clean and free from corrosion

- Displaces water and oil from metal surfaces

- Saves time and money compared to other messy rust preventative methods

- Replaces hazardous oils, flammable solvents and sticky rust preventatives

- Formulation is non-hazardous, non-flammable and environmentally friendly

- Ready to use and VOC free

- If necessary, can be removed easily with mild detergents or cleaners

In the commercial setting, Dry Coat can be applied via:

1. Non-atomizing Spray

2. Dip

3. Flowcoat

If using spray application, entire surface of metal must be covered. If applying via dip or submersion, allow excess Dry Coat to drain or “flow off” of metal part leaving the correct amount of Dry Coat on the metal surface. While it is always best to use Dry Coat on a clean, metal surface to ensure the optimal rust prevention protection, it is not a requirement for product to work.

In simplest terms, Dry Coat will protect metal items stored indoors for one year. The effective time of Dry Coat’s protection can be impacted by the degree of exposure to ambient conditions (such as the humidity level, temperature, and air-flow as well as temperature cycles of condensation or evaporation). Dry Coat’s protection can be extended when metal parts are enclosed in storage or when combined with other ARMOR products.

Dry time depends on ambient conditions such as temperature, humidity and airflow. When conditions are ideal, dry time is approximately 30 minutes. If needed, the use of a fan on a low setting or low heat from an industrial oven or heated blower (recommended temperature and exposure limit for Dry Coat is 180˚ F (82˚ C) are suggested options to help to accelerate the drying process.

Proper storage temperatures for Dry Coat are between 40°F and 140°F. Once applied and dry, Dry Coat will withstand temperatures up to 300°F for short durations (30 minutes or less). For longer durations, a maximum temperature of 180°F is recommended.

Dry Coat was designed to dry-to-the-touch, however, dry time is directly affected by how fast the water portion of Dry Coat’s water-based formula is able to evaporate into the air. The more humid the conditions the longer this will take. Dry time depends on ambient conditions such as temperature, humidity and airflow. When conditions are ideal, dry time is approximately 30 minutes. If needed, the use of a fan on a low setting or heat via an industrial oven or blower (recommended temperature and exposure limit for Dry Coat is 180˚F (82˚ C) are suggested options to help to accelerate the drying process.

Dry Coat provides a protective coating that is approx. 0.5–0.8 microns, or 0.02–0.03 mils thick. For comparison a human hair is 40-50 microns or a piece of photocopy paper is approximately 80 microns thick.

Dry Coat offers two forms of rust protection to help eliminate the need for concern as to whether your application method was precise in covering the entire metal part. The first is the physical barrier provided through the application of Dry Coat to the metal’s surface. The second is the release of a Vapor Corrosion Inhibitor (VCI) that is a component of the Dry Coat formula.When your Dry Coat-covered metal part is stored inside a container (bag, box, storage tub), the VCI vapor that is a part of the chemistry of Dry Coat will attach to any metal surface that wasn’t physically covered and form an invisible, thin film to protect metal from rust. This combination of the physical coating on the metal’s surface and the VCI chemistry that works in vapor offer peace of mind that your metal part is protected.

It depends–depletion of active ingredients, contamination and bacteria growth would be the major concerns. Depletion and contamination causing corrosion issues can be determined by the ARMOR ASTM D4627 modified chip test. This test could be performed at the end of a shift and read the next day to determine if the Dry Coat is still performing as desired. The results could be used to set a scheduled cleaning routine and once that is determined, you would not have to perform this chip test as often. Bacteria/mold growth can be determined by standard BioSticks or any other dip bacteria test indicator. Follow guidelines on test packaging to determine ranges that meet your needs

Excessive blowing could remove the Dry Coat from the metal’s surface–only use the minimum necessary to achieve desired results.

Dry Coat dries to a tack-free finish that is clear and nearly undetectable and it will not interfere with advanced processing such as stamping, grinding, cutting, welding, or burnishing. It does not require removal before the part is placed in service. Dry Coat will be easily removed with standard industrial pre-treatments or common metal cleaning solutions.
