Bioban® P-1487 Antimicrobial

• Uses in Metalworking Fluids - In laboratory tests, repräsentative metalworldng fluid emulsions and Bioban® P-1487 Antimicrobial were placed in a continuous circulating System containing iron Chips to simulate industrial use conditions. The System was inoculated initially and at weekly intervals thereafter with a heavily- contaminated emulsifiable metalworking fluid. In such tests, most oil-based fluid emulsions containing 1000 ppm of Bioban® P-1487 Antimicrobial resist gross microbial contamination for at least six weeks. At a concentration of 500 ppm, its effectiveness lasts from two to four weeks. In similar laboratory tests, 100 ppm - 200 ppm of Bioban® P-1487 Antimicrobial introduced at weekly intervals usually is effective in controlling gross microbial contamination over a period of several weeks at ambient temperatures.
• Storage Stability in Concentrates - A dosage rate of 1000 ppm in the undiluted fluid is recommended. Representative oil-based metalworking-fluid concentrates containing 2.5 % concentration of Bioban® P-1487 Antimicrobial were stored for two months at 50 °C. Another set of samples was stored for one year at ambient temperatures. Emulsions prepared from these concentrates still resisted gross microbial contamination for at least six weeks when tested in the circulating system as above. Specific formulations of metalworking fluid concentrates must be examined to determine their individual stability with Bioban® P-1487 Antimicrobial under storage conditions. Likewise, emulsions prepared from these concentrates should be tested for the most practical concentration of Bioban® P-1487 Antimicrobial to control microbial contamination.
• Addition to Concentrates - Bioban® P-1487 Antimicrobial is highly miscible with metalworking fluid concentrates. However, it is recommended that Bioban® P-1487 Antimicrobial be added to the concentrate as the last ingredient. Also, the concentrate should be cooled to a temperature of less than 32 °C which will lessen the chance of decomposition. Linder some conditions of use, Bioban® P-1487 Antimicrobial will decompose to release a vapor which causes tearing of the eyes. Some practices which will lessen the possibility of such an occurrence are:

1. Do not add Bioban® P-1487 Antimicrobial to diluted fluids with a pH of less than 7.5.
2. Do not add Bioban® P-1487 Antimicrobial to fluids undergoing "Ammonia Blush."
3. Whenever a fresh Charge of fluid is made, pretreat dilution water with AMP-95TM (2-amino-2-methyl- 1-propanol) to achieve a level of 1000 ppm (0.1 %).

• Die Cast Lubricants and Mold-Release Agents - Bioban® P-1487 Antimicrobial is effective against bacteria and fungi which can cause Problems in die cast lubricants and moldrelease agents for plastics. For efficient antimicrobial activity, a concentration of 100 ppm is suggested. Stability testing should be performed to ensure compatibility in specific formulations. A pH of 7 or above should be maintained.

Bioban® P-1487 Antimicrobial can be shipped and stored in ordinary Steel Containers. While there maybe some darkening on prolonged storage, this does not impair its antimicrobial activity. Do not subject to pH below 6.0, or decomposition will occur. Bioban® P-1487 Antimicrobial can be shipped and stored at normal ambient temperature (above 10 °C) without phase change. At lower temperatures, crystallization in the product may occur because of extreme cooling. Should this occur, the product may be liquefied by immersing the drum in warm water or storing it in a heated area until the crystals thaw, If Bioban® P-1487 Antimicrobial is frozen or partially frozen when received, do not heat above 35 °C in any thawing Operation. Under no circumstances should steam, open flame or band heater be used to thaw Bioban® P-1487 Antimicrobial.
