Who Can Use Our Products?

nanoGriptech has had a long-standing and valued relationship with the U.S. Department of Defense (DoD). Recognizing nanoGriptech’s technology, DoD has supported development of fastening solutions for chem-biohazard suits worn by first responders and military personnel. nanoGriptech’s products can be used in a wide range of applications related to personal safety and biohazards. nanoGriptech’s products are less permeable to chemical and biological contaminants, thus providing enhanced safety.

Product Applications

Face Masks

Masks are a critical tool for first responders, miners, HAZMAT teams and the military. These safety and defense users need a mask that is tight and secure and grips their skin without using sticky adhesives or rough abrasives.

The Technology

Elastomers which have been molded into nanoGriptech’s Setex Gecko Grip™ structures demonstrate up to 3X the coefficients of friction on wet, sweaty and oily skin. For such materials, the company developed and patented a method to produce micropatterned tooling surfaces using injection molding or other molding processes.

The technology enables our customers to mass-produce molded parts with friction enhancing Setex Gecko Grip surfaces using the same materials, processes and vendors they currently use.

Setex Gecko Grip is a high friction microfiber surface inspired by the microscopic hairs, or setae, of a gecko’s foot that can be incorporated into injection molded parts.

nanoGriptech uses the molded tool’s surface so the resulting molded part is produced with high friction microfibers on the surface, directly integrated and made from the same material as the part. These microfiber molded parts, using custom plastics, gain a significant increase in the coefficient of friction, typically over 200% to skin in slick conditions.

Hazmat and Surgical Suits

A high pressure resistant, flexible, hermetic closure system is required to protect against hazardous gas exposure. These barriers include seals on collective protection systems, inflatable shelters, vestibule attachments, body bags, chemical/biological protective apparel, or systems for transportation of sick individuals. Conventional fastening options for such applications generally consist of zippers, hook and loop closures, or zip-track systems, which can allow permeation of chemical and biological contaminants.

The Technology

Setex Ultra-Thin Fastener™ is a unique, conformable bonding system. This two-part closure solution consists of a mating surface component and a dry adhesive microfiber component. Setex Ultra-Thin Fastener is created on a thermoplastic polyurethane (TPU) film. The TPU film can be bonded to a wide variety of substrates, including textiles, plastics, natural products (paper, leather) and metals, and is resistant to home washing and dry cleaning.
