Thermal Insulation Nano-Paint

Abstract This interim report documents the formulation and preliminary evaluation of a thin-film thermal-insulation nano-paint based on acrylic and polyurethane binders loaded with porous silica/aerogel fillers, applied over substrate-appropriate primers (metals, concrete, wood/MDF). The scope covers application notes, basic thermal characterization at elevated setpoints, and electrochemical screening under a benign, indoor-service electrolyte. Thermal tests at matched heat input show reduced coated-surface temperatures relative to uncoated controls, supporting energy-efficiency potential in service. At lower operating temperatures, the same effect supports personnel safety by lowering touch temperatures. Electrochemically, EIS indicated a stable, high-impedance barrier over five weeks (including heated specimens), whereas LPR currents were near the instrument noise floor, precluding reliable icorr extraction. No quantitative corrosion-rate claims are made at this stage. A subsequent phase will add validated LPR, extended EIS with equivalent-circuit fits, longer-term and/or cyclic exposures aligned to the intended service envelope, and comparative matrices (bare / primer-only / primer+topcoat) to isolate any incremental contribution of the insulation layer beyond the primer
