Applications & Uses
- Amount to Use
The concentration required to adequately preserve your product depends on several factors. These include the susceptibility of the system to microbiological degradation, the extent to which microorganisms can gain access, the species involved, pH, temperature, and length of time for which protection is required.
Results of initial studies indicate that a concentration of PROXEL MB4 Antimicrobial in the range 0.1-0.3% should be sufficient for most applications. Since the effective concentration can be dependent on several factors it is recommended that a testing program can be undertaken to determine the most cost-effective dose for your application.
Testing should take into account chemical compatibility/stability, plant hygiene conditions, susceptibility of the product to contamination, and the typical organisms involved.
- Applications
The product is effective in polymer emulsions, paints, adhesives, pigment dispersions and household products.
Properties
- Physical Form
- Typical Physical Properties
- Preservative Properties
This product is effective against a range of problem microorganisms some of which are listed in Table 1. Please note that Minimum Inhibitory Concentrations (MIC) do not represent effective in-use concentrations which should be discussed with your local Arch representative.
PROXEL MB4 Antimicrobial has a non-specific mode of action which means that bacterial resistance is very unlikely to occur. Detailed information on the mode of action is available on request.
- Compatibility
- Avoid strong alkaline conditions, oxidizing agents, reducing agents, amines and mercaptans.
