To tackle the challenges of urban graffiti ("urban psoriasis") and metal corrosion, IOTA Silicone has launched the polysilazane resin IOTA 9150, providing a long-lasting anti-graffiti solution for architecture. Unlike traditional high-temperature curing coatings, this product cures at room temperature by reacting with surface hydroxyl (-OH) groups to form a cross-linked structure. It achieves a hardness of 9H and is non-flammable and UV-resistant after curing, while remaining transparent so as not to obscure the substrate's original appearance. It features a water contact angle of 105°, allows for the easy removal of oil-based spray paint, and resists alcohol and ketone solvents; with Grade 0 adhesion, it also provides effective rust protection. Ideal for the current peak season of urban renewal and summer cityscape maintenance, this single-component product is easy to apply: it is touch-dry in just 2 hours, reaches 6H hardness in 3 days at room temperature (or 8H with heat treatment), and is suitable for applications such as streetlights and viaducts. IOTA 9150 is now in stable mass production and has passed authoritative testing, leveraging silicone technology to help create cleaner cities.
