FAQs

MDF-500®’s decontamination formula is a complex mixture of organic and inorganic chemicals that produce simultaneous reactions that destroy both the chemical and biological materials on contact. Chemical formulae, such as MDF-500®, that destroy the spore-forming microorganisms, are called sporicides. This is synonymous with the term “sterilizer.”

A sterilizer is an antimicrobial chemical formula that destroys or eliminates all form of microbial life in the inanimate environment, including bacteria spores.

Bacteria spores are the most difficult of the microorganisms to destroy. Therefore, if a formula can destroy bacteria spores it can eradicate all types of microorganisms (all types of bacteria, fungi, mold, viruses and spores).  

MDF-500® destroys microorganisms by punching holes in their membrane, leading to an osmotic imbalance, causing the organism to implode, destroying it completely. MDF-500® then destroys all of the remaining parts of the organism, preventing it from any form of replication. The science is such that when Part A and Part B are combined in equal amounts, a new compound is formed called an accelerated organic peroxygen.

MDF-500® provides these two steps in a single application: the quaternary amines in part A penetrate the cell wall, and the hydrogen peroxide in part B then oxidizes critical substances inside the cell.

The solution kills mold, mildew, and fungal spores at 99.99999 (Log 7 Kill) rating.

MDF-500® then “weighs” down the dead spores, they drop to the surface and can be Hepa-vacced or simply wiped away.

MDF-500® for smoke works in reverse, the peroxide finishes the oxidation process started by the fire (this is what causes the odor) and then the detergent in part A is a very effective tool for the washing away the smoke residue.

Example: anthrax

Anthrax is a spore-forming microorganism called an endospore. An endospore forms a dormant non-reproductive structure produced by certain bacteria. The formation of an endospore is typically triggered by a lack of nutrients and usually occurs in Gram positive bacteria in endospore formation when it divides the cell wall with one side of engulfing the other. MDF-500® destroys endospores by disrupting the cell wall or by weakening the cytoplasmic membrane, which allows MDF-500® to enter the cell, interrupt the cellular metabolism and reproduction. MDF-500® also changes the osmotic pressure around the cell, which causes an imbalance in the internal cellular pressure resulting in the total collapse of the cellular membrane.

Less product, more coverage:

• A gallon of MDF-500® (A+B) treats 2500-4000 sq. ft in a residential and roughly 7,500 sq. ft in commercial and area application depending on the structure contents.
• MDF-500® is both the safest and the strongest product on the market today making it possible to reduce spore counts and neutralize odors in large spaces effectively with a limited quantity of product when compared to the effectiveness and coverage of other products.
• Faster turnaround time. When MDF-500® is used correctly, the first time is the testing rule. Removing equipment before last fogging can save a trip back to the site.
• Because of superior efficacy, fogging with MDF-500® can reduce the need for costly equipment and manpower required to complete the typical mold and/or mildew remediation.
• Non-destructive remediation may drastically reduce the amount of structural removal necessary which saves client costs and reduces the cost of labor and time for the contractor.
• Odorless: once dried, does not leave an odor behind.
• Color free: once dried, does not leave any discoloration behind, drying clear.
• Application by the ULV sprayer is the most effective method for application.
• Will remain active for 8 hours when wet. The mixed product becomes inert after this time.

MDF-500® is a blend that includes ordinary household substances such as those found in hair conditioner and laundry detergent. Once inert, after the 8 hour activation (life), it dilutes to a neutral PH of 9.8 and only carries a biohazard rating of 1.

MDF-500® can be applied through foaming apparatus, low-pressure sprayers, mopping, and soaking systems. Direct liquid infusion may be recommended per treatment situation.

While chlorine and bleach solutions will neutralize many biological and chemical agents, the run-off is still hazardous, and the product itself is highly corrosive. Once applied and cleaned, the run off must be contained and disposed of in accordance with EPA regulations.

WARNING: Do not use bleach!

• OSHA (Occupational Safety and Health Administration and the EPA (Environmental Protection Agency) have stopped recommending the use of liquid bleach for mold remediation. They have edited their publication “A brief guide to mold and moisture and your home” to exclude the use of bleach as a means to kill mold.
• The chemical properties of bleach prevent it from soaking into porous materials.
• Bleach will only remove the stain from the surface, but will not kill the mold spore roots. The remaining roots will continue to grow back worse than before.
• The active ingredient in bleach is chlorine. More than 90% of bleach is water. The chlorine evaporates quickly, and you are left with material you just soaked with water, which mold leaves.
• Bleach will break down wood and weaken structural support.
• When bleach comes in contact with any type of ammonia, a deadly gas is released. Urine contains ammonia!
• When bleach evaporates it releases Dioxins, a known cancer-causing chemical.
• Bleach is highly corrosive to skin and metal surfaces.

Our manufacturer’s decontamination formula, Modec’s MDF-200®, is the EPA-registered commercial version of Sandia Lab’s DF 200, and is a manufactured pursuant to its license number 15-N08036 with the Sandia Corp. Modec’s MDF-200® is registered with the USEPA under FIRFA No. 91899-1/2.

MDF-500® is manufactured identically to the original specifications of the original specifications of the original Modec DF 200 in accordance with Part A and Part B without the Part C, optional accelerator (Diacetin). Combined Parts A, B, and C make the MDF-200® formulation.

Since 1996, under pursuant licenses, we have manufactured the environmentally friendly decontaminates and microorganism inhibitors MDF-200® (DF-200) and MDF-500®. These two decontamination chemicals have a wide range of uses. Our manufacturer represents a skilled team that has more than 65 years of combined experience in the chemical formulation, manufacturing and distribution spheres. Our manufacturer is proud to offer the finest decontamination products available on the market today. Our manufacturer is a disabled veteran-owned small business.

Yes. After the fog dries, all that remains is a microscopically thin (invisible) dry film on all horizontal surfaces. This film is simply damp mopped or wiped from the surfaces and floors usually only recommended (needed) for food service areas as determined by the contractor.

MDF-500® has been tested and is successful on most any non-porous sealed surfaces.

It has specifically tested as safe for application on glass, laminated surfaces, metal, stainless steel, glazed porcelain, glazed ceramic, sealed granite, sealed marble, plastic (such as polycarbonate, polyvinylchloride, polystyrene or polypropylene), sealed limestone, sealed slate, sealed stone, sealed terra cotta, sealed terrazzo, chrome, Plexiglas®, vanity tops, and virtually all sealed wood surfaces.

Yes. All electrical devices such be un-plugged/switched off during the fogging process. Extensive testing has been done on computers and no adverse effects have been shown from our research.

MDF-500® is a skin and mucus membrane irritant. Do not get in eyes, or skin, or on clothing. We recommend the user wear protective eyeglasses (goggles, face shields, safety glasses), protective clothing and waterproof gloves.

MDF-500® is harmful if swallowed. The vapors may cause respiratory irritation. When contamination is discovered in a confined area, the use of a mask or pesticide respirator is recommended. If ingested, contact a poison control center.

MDF-500® will not damage or stain most fabrics and is safe on most non-porous surfaces.

Yes. With a final pH level of 9.8, MDF-500® meets NFPA 1851 and has been tested per NFPA 1971 standards.

MDF-500® will freeze at a 32 Fahrenheit (0 Celsius), with a boiling point at 212 Fahrenheit (93 Celsius). MDF-500® will begin to degrade at a higher rate when subjected to temperatures in excess of 120 Fahrenheit (49 Celsius). When Parts A + B are mixed, the freezing point of the solution remains the same at 32 Fahrenheit (0 Celsius). We recommend storing the MDF-500® components in a cool dry environment protected from dry sunlight or UV light.
