With the growing momentum of urban renewal and home modifications for the elderly, "invisible protection" for architectural surfaces and everyday items has become a focal point. Unlike traditional organic coatings—which are prone to yellowing and lack weather resistance—IOTA-130 (Si28), a tetraethyl orthosilicate (TEOS) product from the IOTA silicone family, offers a robust inorganic solution. This high-purity liquid (≥98% purity) undergoes gentle hydrolysis upon contact with atmospheric moisture, self-crosslinking to form a silica network akin to silica sol; the only by-product is evaporating ethanol, leaving behind no irritating residues. Beyond penetrating stone and concrete to reinforce the substrate, it transforms into an ultra-hard, scratch-resistant coating on resin lenses, plastic lamp covers, and automotive touchscreens, alleviating concerns about daily scratches. In the home, marble countertops and shower glass treated with this product become stain- and wear-resistant; water spots and oil stains wipe away instantly, keeping surfaces looking new for the long term. Through this innovation, IOTA Silicone creates a reassuring "silicone shield" for households, returning protection to its inorganic, authentic roots.
