The WEICON WL epoxy resin system is used to coat surfaces that are subject to stresses. It has a high adhesive strength, especially on stainless steel. It is liquid, sprayable, spreadable (can be applied with a brush), self-levelling, retains residual elasticity, is ceramic-filled and chemical-resistant. Owing to its long pot life, WEICON WL can be used for applications with higher ambient temperatures or for larger surfaces. Due to the high flowability of WEICON WL, it is important to ensure a low layer thickness and to observe the layer sequence time. WEICON WL is well suited for a system build-up in combination with other Plastic Metal types. For example, the 2-component epoxy resin can be used as a primer when lining pump casings made of stainless steel that are subject to heavy stress. The surface coating can be used in the field of wastewater technology, on pumps, in water pumping, in mechanical and plant engineering, in apparatus engineering and in many other areas of industry.
