ISTN’s Anti-Reflection technology combines the high transmission properties of a vacuum coating with the ease of processing associated with liquid coatings (dip, spin, roll). This allows ISTN’s liquid AR coating to be applied to many different substrates with various sizes and shapes. Some of the key applications that benefit from increased transmission include flat panel displays, solar panels, and eyeglasses.
ISTN’s CSMG™ (Chemically Surface Modified Gel) technology, selectively removes heavy metals from water using a unique nanopore reactive adsorbent structure that combines the superior adsorption capacity of open-channel silica, which has a surface area between 50 to 100 m²/g, and the ability to reduce heavy metal ions to metallic form, to deliver superior capacity, selectivity and speed. CSMG is synthesized by combining freshly produced silica gel with molecular recognition functional groups and can be used in standalone form or as part of an existing operating system. By integrating the adsorption and reaction functions and utilizing a powerful yet cost-effective recipe, ISTN has created a high-potential platform technology that will impact a variety of niches within the multi-billion dollar water treatment market, including the recovery of precious metals such as palladium, gold and silver and the removal of highly toxic elements such as mercury to trace levels to comply with strict environmental regulations.

ISTN's newly formulated water treatment material based on CSMG platform technology is currently in late-stage product development. These nanopore reactive adsorption beads target applications involving slow-moving aqueous wastewater containing low level of lead, cadmium, zinc, or copper.

Anti-Fog (AF) PET Film Product Features • Outstanding Long-Lasting AF Performance – Pass EN 168 for Mist Retardant Anti-Fog coatings. • Excellent Water Resistance, Superior Durability – The coating will retain effective Anti-Fog properties after repeated cleaning with water and normal commercial glass and lens cleaners. • Excellent Scratch Resistance, Hardness, and Impact resistance – Scratch resistance better than most plastic substrates such as PC, TAC, PET. This coating provides reasonable mar protection to substrates without hard coat. • Excellent Mechanical Integrity in Wet State – Scratch resistance in wet state outperforms most AF coatings available in the market. Coating will not swell and cause failures under very humid conditions and relatively high temperatures. • Easy to Clean – No dust tenaciousness, and easily cleaned under running water. • Excellent Formability and Good Chemical Resistance • Excellent Coating Appearance – Improves the transmission of the PET substrate. No haze, blushing, and other optical defects.

ISTN proudly offers TRI-CLEAR™, an optically clear adhesive film with permanent anti-fog properties. Because fog impairs the use of many everyday products – while often being unavoidable – TRI-CLEAR™ is a necessity for maximizing visibility in applications that range from bathroom mirrors to ski goggles. TRI-CLEAR™ is more cost-efficient than anti-fog heating devices, and also easily replaceable and removeable (unlike permanent coatings). The film represents the highest optical quality among the FOGuard ® family of products, and is ideal for anti-fog uses that require optimum clarity. RECOMMENDED APPLICATIONS Protective Eyewear: Military helmets and masks; Safety lenses; Sporting goggles Glass Panels: Bathroom mirrors; Freezer display doors; Window glass Electronic Devices: Camera enclosures; Incubators; LCD panels THE TRI-CLEAR™ ADVANTAGE NO FOG: Effectively prevents fogging from both intermittent (e.g. breathing) and continuous exposure in most applications. CLARITY: Uses same optically clear substrate as photographic film, providing superior visibility compared to other anti-fog films. RESISTANT TO WATER / CHEMICALS: Retains anti-fog properties after exposure to water and a number of chemicals, including bleach and other cleaners. DURABILITY: High thermal stability and resistance to extreme temperatures, scratches and impact, permitting long-term use. SAFETY / COMFORT: Hypoallergenic and safe to the touch –favorable to applications on visors, eyewear and other headgear. AVAILABLE NOW: FOGuard ® TRI-CLEAR™ anti-fog film is currently available from ISTN in custom sizes and master rolls. Tiny water droplets form, creating fog. Adsorbs water droplets, forming thin, transparent film.
