2An Anti-Microbial Monomer/Polymer Offering
Cleaner, Faster, Safer, More Comprehensive
Anti-Microbial Protection
- Not a serious toxin and danger like Triclosan
- Cheaper, faster-acting than silver/copper-based
compounds - Non-leaching stays within the material
- Extends functional life of product treated
- Produces self sanitizing materials
- Can be applied as spray, in solution, or as
powder
3Benefits
- Non- leaching, permanent antimicrobial surface
- Biocide has been proven to be nontoxic, to
contain no carcinogens, teratogens, mutagens or
reproductive toxins - Active kills instantly by disrupting the cell
membrane, eliminating any possibility of
mutation, adaptation or resistance - Broad kill range
- Environmentally friendly-EPA and FDA approved
- The technology can be used on wide range of
materials. - Provides both collective and individual
bio-defense protection. - Added cost is modest compared to benefit.
Approximately 2-5 cents per square foot of
coating or 5 to 50 cents per pound of plastic or
resin.
4Typical Applications
- Individual and collective protection
- Clothing, Uniforms, and other Wearable Fabrics
- Carbon filters
- Tent Webbing and canvas materials
- Painted Surfaces
- Laminate and counter tops in field operations
- Contamination avoidance
- Bulk polymer Resins/ Plastics
- Resin Concentrates
- Sanitation and Health Safety Equipment
- Medical treatment
- Medical Devices
- Surgical drapes and wound dressings
- Nano coatings
- Interior surfaces/ walls floors
- HVAC ducts
- Filters
5Action The Poly-Quat AntimicrobialIs bound to
the product controlling Microbes on contact
- Is substantive to the product substrate
- Is not consumed when challenged by microbes
- Mechanically destroys the cell
- Will not cause microbial adaptation
- Functions equally in a nano coating or bulk
substrate treatment process - Can be added into manufacturing process or
applied later - Can be combined with other surface protectants
(e.g., water repellant, anti-static)
6The Antimicrobial AgentWhy did we choose this
antimicrobial?
- 3 (trimethoxysilyl)propyldimethyloctadecyl
ammonium chloride - Unique in the scope of its kill range/broad kill
- Bacteria (gram positive)
- Staphylococcus Aureus
- Bacteria (gram negative)
- Salmonella Typhosa
- Yeast
- Algae
- Fungi
- EPA Registered
- Chemically active
