Antimicrobials for bacterial and fungal control
OVERVIEW
Aquaserv pioneered the use of fungicides in gypsum wall board to provide mold resistance. In partnership with the Dow Chemical Company, Fungiblock™ was introduced in 2003 and is a still a leading product for this market. Aquaserv has added to this a second fungicide, Klarix™ 4000 which provide added performance. In addition, Aquaserv offers several biocides that are used in plant manufacture and in-can preservation of caulks, adhesives, joint compounds, and other construction related products. Bacterial activity in these products can cause spoiling, loss of viscosity and loss of performance. Additionally, in-plant biocides are useful to control bacterial contamination in incoming raw materials and may also be needed to rework stored product. Whatever your need, Aquaserv is here to help determine the best biocide option, and customer support from the Aquaserv team.
Benefits:
- Preserving product integrity
- Minimizing waste and rework
- Easy product dosing
- Performance against standard testing protocols
FUNGIBLOCK™
Fungiblock™ is a broad spectrum industrial fungicide. It is highly effective against a broad list of fungi and mold. In 2003, Aquaserv discovered the capably of this fungicide in resisting the growth of mold on paper used to produce gypsum wallboard. In partnership with Dupont, Aquaserv became the first to introduce a fungicide to this market. Fungiblock™ remains the most widely used product today. Fungiblock™ attacks the mold organism, preventing the cell from growing, breathing, reproducing, and spreading. Standard industry tests have demonstrated that Fungiblock™ effectively prevents formation of mold on a variety of building materials and offers lasting protection. Beyond the gypsum paper, Fungiblock™ can also be used in the gypsum core and other fiberglass covered boards, joint compounds, caulks, adhesives, paints, and industrial coatings. A key to the success of this product has been the broad spectrum performance, ease of incorporation, low water solubility, low toxicity, and customer support from the Aquaserv / Dupont partnership.
Applications:
- Gypsum board paper
- Gypsum board core treatment
- Caulks and adhesives
- Paints and industrial coatings
- Joint compounds
Benefits:
- Broad spectrum activity
- Low toxicity
- Ease of use
- Proven performance
- Low water solubility

KLARIX™ 4000
Klarix™ 4000 is the result of innovative product development. This fungicide provides increased resistance to molds when it is incorporated with Fungiblock™ in gypsum paper. While it has excellent affinity for the paper as a fungicide, it also has anti-bacterial properties. We have experienced that this product can clean heavily contaminated paper mill systems. Klarix™ 4000 base product chemistry was awarded the Presidents Green Chemistry Award for its outstanding environmental profile. It is easily dosed to systems at very low addition levels, provides both fungicidal and bactericidal performance, and works synergistically with Fungiblock™ to provide the highest performance at the lowest overall cost.
Applications:
- Gypsum board paper
- General paperboard
- Gypsum Board Core treatment
- Paper mill cleanup
Benefits:
- Broad spectrum activity
- Dual Performance Capability
- Low toxicity
- Ease of use
- Low Use cost
- Proven performance
- Low water solubility
Bronopol
1,3-propanediol (bronopol) is a broad spectrum biocide that is highly effective in controlling bacterial growth in industrial process systems such as industrial process waters, recirculating water, cooling towers, evaporative condensers, oil production and transport, and pulp and paper production. Bronopol is primarily used in fluid, filler and pigment preservative applications such as starch, pigment and extender slurries, printing inks, fountain solutions, paints, latex and antifoam emulsion systems. It is particularly effective against Pseudomonas bacteria.
Applications:
- Paint, water-based coating application tanks and latex
- Adhesives
- In-can preservation
- Water-based printing inks and fount solutions
- Absorbent clays, corn cobs, and ground wood
- Paper mill process water
- paper mills-bulk pulp
- Starch, pigment and extender slurries
- Joint compound preservation
- Clay slurry preservation
- Water-based agricultural pesticide concentrates
- Consumer, household, and institutional products
- Industrial recirculating water cooling towers and evaporative condensers
- Industrial process water
- Metalworking fluids
- Oil and gas fluids
Benefits:
- Broad spectrum activity
- Synergistic with Isothiazalinones
- Compatible with a broad range of materials
- Effective against Pseudomonas sp.
- Can be used in elevated pH systems
- Readily biodegradable

CHLORO-METHYL-ISOTHIZAOLINONE (CMIT/MIT)
CMIT/MIT is a broad spectrum biocidal mixture that is highly effective at very low concentrations in controlling both planktonic and sessile bacteria, fungi and algae. It is an excellent in-can preservative at very low levels. CMIT/MIT causes immediate inhibition of growth on contact with active microorganisms. The growth inhibition rapidly becomes irreversible and results in cell death. Even before death occurs, the treated organism is unable to synthesize degradative enzymes or the exopolymers which facilitate surface adhesion and biofilm formation.
CMIT/MIT is effective in controlling a wide variety of algae, bacteria and fungi. This broad spectrum activity reduces the need for multiple biocides and lessens the risk of dosing error. CMIT/MIT provides effective preservation at typical use levels of 15 ppm active ingredient in industrial products. Extensive toxicological testing has shown CMIT/MIT to exhibit low toxicity at recommended use levels.
Applications:
- Paint, water-based coating application tanks and latex
- Adhesives
- Mineral slurries
- In-can preservation
- Caulks
- Defoamers
- Fiberglas sizing solutions
- Emulsion
- Dispersions
- Surface preparation compounds such as joint compounds
Benefits:
- Broad spectrum activity
- Highly effective at low dosage rates
- Readily biodegradable
- Miscible in most systems
- Easy deactivation when desired
- Excellent environmental profile
- Non-bioaccumulative
- Non-persistent
- Good toxicity profile

DBNPA
DBNPA is a broad spectrum, fast-acting biocide that is highly effective at low concentrations against aerobic and anaerobic bacteria such as slime-forming bacteria, sulfate-reducing bacteria (SRB) and acid-producing bacteria (APB). Its biocidal activity is due to the ability of DBNPA to inhibit cell respiration and enzyme activity, resulting in cell death. DBNPA has an outstanding environmental profile due to its fast degradation to carbon dioxide, ammonia, and bromide ion, all of which are considered innocuous to the environment. Aquaserv offers a line of DBNPA-based solutions, containing up to 20 percent active by weight. These DBNPA-based products have found widespread use in a variety of applications for reducing microbiological contamination in raw materials and/or finished products that require EPA approval.

- Raw material clean-up
- Finished product recovery
- Process equipment cleaning
- Water system cleaning
