+ What is Plasma Guard STV®?

Plasma Guard STV® is a Water-based Rust and Corrosion Inhibitor. 

Plasma Guard STV® is a environmentally friendly, biostable, water-based rust and corrosion inhibitor and coolant for plasma/oxy/waterjet cutting table systems. Great for cooling cutting surfaces, protects ferrous machinery components and processed parts from rust, corrosion, bacteria, mold, and fungus for extended periods.

GREAT FOR: Ferrous, Stainless Steel, Non-ferrous, & Galvanized surfaces.

+ Concentration, pH Levels and Water

The Anti-Rust Solution is designed to be used for cutting steel in stagnant or agitated water tables to eliminate steel corrosion, rancid odors and insect infestation. Plasma Guard STV® is formulated to be used in large open tanks commonly for plasma torch, oxy–acetylene and M.A.P.P. gas metal cutting operations where water is employed as a coolant and sound suppressant. A built in blue indicator aids in the proper control of the solution concentration. One can also monitor concentration levels with Test Strips that check the pH Level.

WATER: For best results, we recommend using Reverse Osmosis (RO) water, but Plasma Guard STV® can be used in all water types if RO water is not available.

MATERIAL: Plasma Guard STV® exhibits comprehensive surface coverage to improve cutting, appearance, quality, and protection when used in recommended concentrations and practices.

+ Staining

Plasma Guard STV® provides a comprehensive integral coverage to leave a clear, non-discernible, non-staining, non-tacky, dry-to-the-touch protective film on the surface after drying.

+ Flammability

Plasma Guard STV® is a Non-Volatile Organic Compound, free of oil and petroleum. It DOES NOT contain oils, solvents, waxes, silicones, nitrites or formaldehyde, and is non-toxic, non-hazardous, non-flammable, and biodegradable.

+ Dry Time and Finishing Operations

Dry time is normally within 60 minutes in most conditions in temperatures above 70°F (21°C) on exposed parts after cutting.

Plasma Guard STV® does not normally need to be removed for further processing or handling, i.e. pickling, painting, welding, and has no adverse effect to weld integrity or the atmosphere.

You can weld, paint, pickle, etc., over Plasma Guard STV® surfaces. It has no adverse effect to weld integrity or the atmosphere and produces good integral bonding.

+ Handling/Storage/Disposal

HANDLING: Wash thoroughly after handling. Wash hands before eating. Avoid contact with eyes. Use with adequate ventilation. Follow all SOS/label precautions. Observe good hygiene practices daily.

STORAGE: Keep container closed when not in use. Store in a dry, well-ventilated place. Normal shelf life is ONE YEAR when stored in temperature ranges of 32°F (0°C) to 100°F (38°C).

DISPOSAL: Plasma Guard STV® improves environmental compliance and reduces waste treatment and disposal costs. Stop the flow of material, if this can be done without risk. Dike and prevent material from entering drains, sewers, or waterways. Absorb with dry/inert absorbent material, and transfer into recovery drum for disposal. Dispose of in accordance with local, state, and federal regulations.

+ Coverage and Protection

Maximum protection is subject to acid-free, weather-protected environments with an Indoor Protection Term of up to 6 months, depending upon dilution and use conditions. Not recommended to be mixed with other metalworking coolants / additives, which may cause adverse effects in performance. The length of time depends on the activity and use rate at which the table operates and the filtering and maintenance performed. If the solution is kept free of heavy oil buildup, debris filtered, and the solution aerated when not in use, this will add to its useful length. Many heavily used tables can run for extended periods with good maintenance practices. When systems start to accumulate metal particle and/or slag buildup, the Plasma Guard STV® solution can be reused (after filtering and checking solution concentration) before adding back to the cleaned system.

RECHARGE: If you should for any reason see any signs of corrosion or rust, please test for correct concentration (send sample to PICO for evaluation), or it may be time for a clean-out and fresh recharge.

+ Evaporation and Maintenance

The recommended water level for your STV®CNC Plasma table should be right above the slats and making contact with the material. Adding the Anti-Rust Solution will help extend the life of your water pans and prevent rust, debris and excess fumes. Knowing evaporation may occur, maintaining an acceptable level of water or submerging your material in water during a cut will help keep the material cool, minimize warping of your metal sheet, reduce the amount of excess fumes and decrease the noise emitted by the Hypertherm® torch. Check periodically to maintain proper concentration of the solution.

Evaporation rates help to evaluate health & fire hazards of a material. A solution with a high evaporation rate will readily form a vapor which could be inhaled or explode. The relative evaporation rate of butyl acetate is 1.0. (butyl acetate (BuAc) = 1.0) 

Plasma Guard STV® has a [MEDIUM] Evaporation Rate of 0.40.

*Important: Depending on your production use of the table, it is recommended to replenish your table every 1 to 3 months time. 

+ Important

Do Not Use Bleach or Swimming Pool Chlorine as a Biocide or Sump Cleaner Additive. Bleach can react with water and a variety of other chemical compounds to generate a gas that is harmful to workers. As bleach degrades, it causes high levels of chlorides to accumulate in the water and other fluids, which will corrode ferrous metals and lead to fluid instability. Bleach should never be directly inhaled, and unprotected exposure (PPE) can cause skin irritation (dermatitis). Overexposure to bleach/ chlorine results in difficulty breathing, coughing, sneezing, throat and nose irritation.

+ Quenching Improves Cut Area Tensile Strength

(This specific paragraph details how an example of General Material Quenching Techniques or Cooling Factors that test alloy steel samples are beneficial. The content in this paragraph is solely to drive the value of the quenching process; it does not necessarily reflect the exact results from using Plasma Guard STV®.) “In order to improve the tensile properties of PCrNi3Mo steel, plasma surface quenching technique was used to treat its surface. The tensile properties of the PCrNi3Mo steel before and after plasma quenching were investigated by using MTS tensile tester, and the stress-strain curves obtained at the same strain rate were compared. The residual stress on the surface of the PCrNi3Mo steel was measured by X-ray diffractometer, and the microstructure and morphology of hardened area after quenching were observed by optical microscope. The results show that the yield strength and tensile strength of the PCrNi3Mo steel after plasma quenching increase by 27.3% and 28.6%, respectively, and the section shrinkage and elongation after fracture decrease by 76.4% and 69.4%, respectively. The fracture surface of the original PCrNi3Mo steel sample shows obvious necking phenomenon, which is ductile fracture, and the toughness of the quenched PCrNi3Mo steel sample is obviously improved but the plastic deformation ability decreases; the surface stress of the sample changes from tensile stress (496.9 MPa) to compressive stress (-942.2 MPa) after plasma quenching; the section of the quenched sample forms crescent-shaped hardening belt, and the fine martensite structure in the crescent replaces the coarse ferrite structure. The deeper the hardened layer formed after quenching is, the higher the tensile strength of the steel is. © 2018, Editorial Office of Transactions of Materials and Heat Treatment.

+ Quenching Reduces Metal Distortion and Warping

Prevent warping/bowing by:

  • Maintaining your Plasma Guard STV® Anti-rust Solution and water levels to help cool the metal during cuts
  • Practice Pausing for Intermittent cutting to allow time fit between long cuts to avoid warping
  • Using Clamping & Restraining fixtures to keep sheet in place to minimize distortion
  • Increasing the speed of the cut if possible.

Expansion, Contraction, conductivity and change of strengths have a combined force to produce distortion. If a high temperature heat source runs across one side, the metal on the heated side will expand in all directions. The plate will bend due to the pressure of the expanding metal. The unheated portion of the sheet will resist bending and place pressure on the heated portion. This pressure on the weakened expanding metal causes metal to flow and thicken the cut area. As the plate cools and contracts, the thickened cut area regains its strength and becomes shorter than its original length because there is no force to reduce the cut area to its original dimension. This produces a curve/bow/warp in the plate in the opposite direction. Final result varies among the metal sheets’ thickness, size, weight, frequency and proximity of cuts.

Important: Underwater cutting is recommended not to exceed 2″ inches in depth of submerged material.
