Antimold for Wallboard Paper


MycoTek is a proprietary blend of Alkyl Dimethyl Benzyl Ammonium Chloride compounds approved and registered with the Environmental Protection Agency (EPA) for use as an antimold in paper products. These molecules work together synergistically to prevent mold growth by destructive interaction with membranes of the organism. The chemistry is temperature stable with no degradation during normal wallboard manufacturing processes.

  • Premium antimold for wallboard paper (patent pending).
  • Highly concentrated liquid.
  • Readily diluted with water for use.
  • Perfect score of 10 on ASTM D-3273*.
  • Stable and can be stored under a wide set of physical conditions.
  • Environmentally friendly, biodegradable in landfill.
  • Safe to use.
  • Cost effective...cost competitive.

  • MycoTek Binds and becomes resident on cellulose by:
    • Ionic bonds Van der Waal and hydrogen bond interactions.
    • Hydrophobic interaction through long carbon side chains.
    • Concentrated as water is removed during the wallboard paper making process.
  • MycoTek Stops mold growth:
    • Paper is a nutritional source for mold.
    • Mycotek is distributed throughout the paper.
    • Close interaction between mold membrane and MycoTek associated with paper results in degradation of mold membrane.
    • Mold cell death results due to cell rupture.
    • MycoTek remains resident on the paper and in the dead mold material keeping new mold growth in check by repeating the killing cycle.

*ASTM D-3273 is a standard testing method.

When tested, as manufactured, in accordance with ASTM D-3273, MycoTek scored a 10 which is the highest level of performance for mold resistance under the ASTM D-3273 test method. The score of 10, in the ASTM D-3273 test, indicates no mold growth, in a 4-week controlled laboratory test. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting.
