Nano-Clear Overcoat

By Nanovere Technologies, LLC

Matte Finish Protective Overcoat Designed to Protect the Warfighter Extends the Service Life of Military Assets Reduced Decontamination by 50X Chemical & Biological Resistance (sarin, anthrax...) Defense Industry Military asset owners commonly apply conventional pigmented CARC (Chemical Agent Resistant Coatings) over steel substrates to mitigate the effects of chemical contamination, chemical attack, environmental exposure including weathering oxidation, corrosion and abrasion. Conventional pigmented CARC coatings alone are currently susceptible to: UV degradation (UV rays, weathering); chemical attack (solvents, acids); chemical absorption (chemical & biological); environmental damage (abrasion, scratching); corrosion damage (salt, chemical attack) Extreme Abrasion Resistance: Only 8.4 mg loss after 1000 cycles, 1 kg Extreme Corrosion Resistance: No Rust After 6000 Hour Salt Spray Testing Extreme Chemical Resistance: Outperformed all CARC Competitors: DEVCOM Weatherproof Technology Matte Clear Overcoating: Return to Service in 24 hours, 99% Retention after 4000 Hours - Xenon WOM What is needed? A high crosslink dense clear matte finish overcoat that protects military assets more thoroughly than conventional pigmented CARC technologies. Nano-Clear Overcoat will dramatically extend the surface life of conventional CARC by 15+ years. Nano-Clear Overcoat is designed to be applied directly "over" pigmented CARC paints, as a clear matte finish overcoating. The Nano-Clear Overcoat dramatically extends the service life of military painted assets by significantly improving decontamination, corrosion resistance, abrasion, scratch, chemical and weathering resistance. Nano-Clear Overcoat significantly reduces decontamination time while preventing biological agents from penetrating into military paint and allows for easier removal during the decontamination process. Nano-Clear Overcoat is manufactured using proprietary 3D nanostructured polymers - producing extreme crosslink density. Nano-Clear Overcoat is a two-component clear matte finish over-coating providing extreme corrosion resistance, abrasion, chemical & UV resistance and reduced surface maintenance. Nano-Clear Overcoat penetrates deep into the pores of CARC paints to dramatically improve corrosion resistance, surface hardness, chemical and long-term UV resistance with 50% reduced surface tension. Nano-Clear Overcoat produces an exceptionally high crosslink dense polymer network designed to withstand harsh environments. Nano-Clear Overcoat is the world's first clear matte finish designed to be applied directly OVER conventional CARC paints. Stonebridge Coatings Laboratory has validated Nano-Clear Overcoat to have the highest scratch resistance and chemical resistance over other leading CARC paints when used alone. What Makes Nano-Clear so Unique? Nano-Engineering Creates Exceptional Crosslink Density. Coatings contain "building blocks" with functional groups. The chemical reaction of these groups during curing forms a network. In most traditional polymers, the network is a linear chain of molecules with low crosslink density. Conversely, we "nano-structured" our clearcoat to have a 3D molecular architecture. The 3D polymer network has an exponentially higher number of crosslinked sites. The result is a tightly knit mesh with unprecedented DMA density. High crosslink density provides highly functional surface properties, including unmatched corrosion resistance, scratch resistance, chemical resistance and UV durability. It also means low surface energy, repelling water (hydrophobic) and aiding in the release of ice, dirt, brake dust, and even concrete dust.
