I1 Smart Fabric protects all kinds of fabrics from water-based stains. It is breathable and extremely durable, thanks to Gtechniq’s unique scientific formula. I1 makes ordinary fabrics waterproof and easy to clean. Use it to prevent soaking, swelling or rotting on any fabric. Ideal for use on your cars convertible roof or interior. Smart Fabric is colour safe. Nano particles that make up I1 Smart Fabric coat each fabric fibre individually, leaving the texture unaffected, allowing the material to breathe. This means stale air will still be able to escape, while repelling water and and oil-based liquids. Even more hydrophobic than its predecessor, I1 Smart Fabric V2 leaves no remnants of a spillage and moisture simply falls off a coated surface. Laboratory testing reveals that I1 V2 repels water to the highest standard set by the American Association of Textile Chemists and Colorists (AATCC) – ISO 5. And wash tests reveal the product remains at its full performance level after being washed on a 40 degree cycle, and even after five washes still performs better than its predecessor. On average I1 will last on a car’s interior for between 6 and 12 months - depending how ‘used’ the surface is. On convertible roofs the product will last for up to 2 years.
