• 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)

Product Development History

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 2013 - UltraTech International, Inc. obtained the worldwide, exclusive commercial rights

• September 2014 – Product is optimized for standard applications and commercial production commences.

Ultra-Ever Shield™ 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+)

Key Performance Results

10

Conformal Fabric Coating

Ultra-Ever Shield™ establishes a polymer coating that encapsulates each fiber of the material and creates durability through cross-linking the individual polymers in a protective matrix.
