3 ECC Durable treatments for ceramic and glass surfaces 3Innovation
Easy Clean Coating 3ECC products are fluoropolymer based materials that chemically react with siliceous substrates Resulting in a durable, invisible nanocoating providing the substrate with water, oil and stain resistance Keeps things looking good longer
Easy Clean Coating Treated with ECC Untreated Liquids roll off ; limestone and stains are easily removed 3Innovation
Easy Clean Coating Treated with ECC Limestone deposits clean off easily Untreated 3Innovation
Consumer benefits of ECC (Sanitary ware - ceramic tiles - glass) Typically applied as optional treatment (V&B ~ 10%) Stains do not spread - easy to remove Hard water deposits easy to remove Less time and effort needed to clean Potential for reduced cleaning frequency No aggressive cleaners needed Lower need for water and detergents Improved hygiene (less residue moisture)
Application of ECC Alcohol or water based dilution containing 0.1-1.0% of ECC and some acid as catalyst Typically applied by spray coating Final thickness of the coating will be less than 100 nm (<0.1 µm or 0.0001 mm)

Quality check on invisible ECC coating? => Contact angle measurement Krüss Drop Shape Analyser DSA-100 (5 µliter water droplet) Untreated ceramic tile Contact angle: 38 Ceramic tile treated with ECC-4000 Contact angle: 110 Due to the fluoropolymer coating, the surface obtains a low surface energy, repelling the droplet and causing a drastic increase in contact angle 3Innovation
Contact angle measurement A measure for the substrate s surface energy Enables to check the coatings integrity Initial (homogeneous) Durability (after abrasive cleaning test) Bonding of ECC to substrate? Adequate coating thickness?
