Lonza antimicrobials are used to increase the useful life of plastic parts and have been proven effective against micro-organisms in a variety of applications at cost-effective use levels.

Prevent Polyurethane from degradation with Lonza antimicrobials

Moisture and organic matter in and on a polyurethane matrix may provide all requirements for microbial growth: organic matter can collect on the PU surface and provide nutrition for microorganisms.

Some polyurethane based polymers can provide all the required nutrients for microorganisms to flourish; some do not. Those polyurethanes that do not supply nutrients for micro-organisms will still accumulate organic matter and moisture from the end-use-environment. Both cases will benefit from the addition of an antimicrobial.

The direct consequence of such growth for PU applications is a degradation of the aesthetics, with appearance of stains, unsightly growth and unpleasant odors.

Vanquish® and Zinc Omadine® antimicrobials are both effective against mold, fungi, and bacteria and offer a high-level of protection of Polyurethane through:

Polyurethane Foams



In addition, Vanquish® and Zinc Omadine® antimicrobials are:
  • Easy to formulate:
    • Vanquish® antimicrobial grades are liquid products fully miscible in polyols and plasticizers and can be pre-mixed in the polyol-side of the polyurethane formulation
    • Zinc Omadine® is available as a neat powder or a 48% Aqueous Dispersion
  • Regulatory Compliant:
    • U.S. EPA, European Biocidal Products Directive
    • Not based on arsenic, TBT, Triclosan

As illustrated in figure 1 below, Vanquish® 100 antimicrobial demonstrates high performance in Polyurethane foam at high use levels where TBT shows less protection at a higher concentration:

> Zinc Omadine® Antimicrobial is shown to be the best performing additive regardless of concentration in this set.
