2. Product Development History
In the mid-2000s, an Army General challenged the Soldier Research Center to develop a “self-cleaning” uniform
Small Business Innovation Research (SBIR) Team:
US Army Soldier RD&E Center (Natick, MA)
Luna Innovations, Inc. (Blacksburg, VA)
6 years and over $2M of SBIR funding (Phases I – IIB)

3. Product Development History
Goals:
Highly repellent, durable coated textiles that resist attraction of liquid and solid contaminants
Minimize battlefield logistics burden - less laundering; detergents unnecessary

4. Product Development History
Coating was lab and field-tested by US Army
Mid 2013 – Product is determined to be ready for commercialization
November UltraTech International, Inc. obtained the worldwide, exclusive commercial rights
September 2014 – Product is optimized for standard applications and commercial production commences.

7. EverShield™ the first Durable Omni Repellent
A new category of High Performance Textile Treatments: Durable Omni Repellent (DOR)
Omniphobic = Hydrophobic + Oleophobic
Water, 155o Octane, 133o
Dual structured coated Nomex fabric showing resistance to water and octane (oil/hydrocarbon).

8. DOR vs DWR
Durable Water Repellent (DWR) treatments repel water and few other liquids (but have limited durability). Durable Omni Repellent (DOR) exceed DWRs by producing performance in textiles that:
Are superhydrophobic
Are oleophobic
Repel debris and resist staining
Retains most performance after numerous washings (50+)

10. Conformal Fabric Coating
EverShield™ establishes a polymer coating that encapsulates each fiber of the material and creates durability through cross-linking the individual polymers in a protective matrix.
