Weicon B4AS 2 Kg

WEICON B4AS is a liquid, antistatic 2-component epoxy resin system with a high proportion of fine mineral fillers. It is used to protect surfaces against wear and corrosion. Due to the combination of high-strength particles with a viscoplastic polymer matrix, the system offers a high level of wear protection. It has good chemical resistance and high abrasion resistance. The coating adheres very well even under vibration and stretching on a wide variety of surfaces and is no-dripping. The wear protection system is free of tar and solvents and cures almost without shrinkage. B4AS is suitable for coating a wide variety of parts, such as rollers, pumps, chutes, conveyors, lifting screws, separators, hoppers, propellers, fans and heat exchangers.

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 B4AS intensively into the surface in crosswise layers by using the Contour Spatula Flexy, in order 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.
