COATIX® EP 4565 Top Coat
COATIX® EP 4565 Top Coat is a two-component, solvent-free, epoxy resin-based top coat material that forms a glossy film. Thanks to its special resin/hardener composition, it offers outstanding resistance to inorganic and organic acids, alkalis and many aggressive chemicals. Its distinctive features are high surface hardness, water and chemical resistance, high mechanical strength and an easy-to-clean, hygienic surface. Being impermeable to carbon dioxide, it protects concrete against carbonation and increases the corrosion resistance of metal surfaces.
Areas of Use
• Chemical and pharmaceutical industry facilities, acid/alkali filling, dosing and storage areas
• Treatment plants, wastewater structures, chemical tanks and plant rooms
• Battery, galvanising, surface finishing and metalworking facilities
• Food, beverage, dairy and paper industry facilities, laboratories
• Factories, warehouses, workshops, aircraft hangars and car parks
• Internal surfaces of water tanks, silos and storage tanks
• As a protective paint on machinery, equipment and building components made of metal
• On wall and floor surfaces; in horizontal and vertical applications
• Areas with heavy forklift traffic and corrosive chemicals
Applied as a top coat on concrete, screed and mineral-based surfaces, and on metal/steel surfaces after a suitable primer coat.
Advantages
• Outstanding resistance to inorganic and organic acids, alkalis, salt solutions and many aggressive chemicals
• Solvent-free; low-emission, can be applied safely in enclosed spaces
• High surface hardness, mechanical strength and abrasion resistance
• Resistant to wastewater, sea water and mineral oils
• Impermeable to carbon dioxide; protects concrete against carbonation
• Increases the corrosion resistance of metal surfaces
• Forms a seamless, hygienic and glossy surface; easy to clean, suitable for steam cleaning
• Can be applied on horizontal and vertical surfaces
• Applied by brush, roller or airless spray
• Can be produced in a wide range of RAL colours

Refer to SDS |
* Excluding metallic, fluorescent and 4000 series colours. The colour shade may change under direct sunlight; this does not affect the performance of the coating.
The technical values stated were obtained at +23°C ambient temperature and 50% relative humidity; times are extended as ambient and surface temperatures fall and shortened as they rise. As viscosity increases at low temperatures, consumption also increases. Consumption values are theoretical; they vary depending on the absorbency and roughness of the surface and the application method. For exact consumption, a controlled trial application must be carried out on site.
