Weicon has recently developed a wear protection epoxy resin, Weicon B4AS. Used to protect surfaces against wear and corrosion, B4AS is suitable for coating heavily stress parts such as rollers, pumps, chutes, conveyors, lifting screws, separators, hoppers, propellers, fans, and heat exchangers.
The system has a high abrasion resistance and protects surfaces in industrial areas where they are exposed to heavy loads and stresses. B4AS is a liquid, antistatic two-component epoxy resin system with a high content of fine mineral fillers. Weicon GmbH states that by combining high-strength particles with a viscoplastic polymer matrix, the system offers high-wear protection.
The epoxy has a good chemical resistance and adheres very well to a wide variety of surfaces – even under extreme loads, such as vibration and elongation. The wear protection system is non-dripping, free of tar and solvents, and cures with virtually no shrinkage. Also, the epoxy resin system can be used wherever chemicals or other aggressive media are conveyed through pipes. Therefore, the product is suitable for applications in the chemical industry, in refineries, in sewage treatment plants and in many other areas.
Plastic metal
The term ‘plastic metal’ describes epoxy resin systems, which consist of two components, one resin and one hardener. Depending on the type, the resin component is mixed with steel, aluminium powder or mineral fillers, all of which improve the technical characteristics, such as the compressive strength and thermal conductivity. With this feature, the B4AS epoxy resin system is suitable for a broad range of applications in different industrial areas.
Plastic metal can be used, for example, in industrial series production for adhesive bonding, coatings and durable repairs on different materials. After mixing the two components, the plastic metal cures at room temperature to a solid, metal-like material, which can then be machined. Once cured, it can be drilled, milled, sanded or filed, if required.
