Weicon B4NV Anti-Stick 2 Kg

WEICON B4NV Anti-Stick is a liquid, grey 2-component epoxy resin system with mineral fillers for the protection of heavily stressed surfaces against aggressive chemicals, corrosion and mechanical wear. It was specially developed for the application with a low-pressure equipment. B4NV Anti-Stick contains special additives that create an anti-stick-slip-effect. The wear protection system has good chemical and thermal resistance. It is free of solvents and cures almost without shrinkage. B4NV Anti-Stick is applied directly to the parts by sandblasting after thorough preparation of the substrate. The coating adheres very well to a wide variety of surfaces and is suitable for a wide variety of parts, such as pipelines, pumps and exhaust installations. In any case, preliminary tests under practical conditions are recommended; especially if the parts are additionally exposed to increased temperature or mechanical stress.

Application

For processing, we recommend an ambient temperature of 20°C (68°C) at less than 85% relative humidity. The highest adhesive strength is achieved when the parts to be processed are heated to >35°C (>95°F) before application. For a thin pre-coat, work WEICON B4NV Anti-Stick intensively into the surface in crosswise layers using the Contour Spatula Flexy to achieve maximum adhesion. By means of this technique, the epoxy resin penetrates well into all cracks and roughness depths. Afterwards, further applications can be carried out straight away, until the desired layer thickness is reached. Make sure that the epoxy resin is applied evenly and without air bubbles. To fill large gaps or holes, fibreglass, expanded metal or other mechanical fixing materials should be used. Finally, the surface can be smoothed easily with the help of a PE film and a rubber roller.
