WEICON HB 300 is pasty, steel-filled and high-temperature-resistant up to +200°C (392°F) (up to 280°C/536°F for a short period of time). It is processed with a mixing ratio of 1:1. The epoxy resin system is also suitable for applications on vertical surfaces and can be used for the repair and bonding of cast and metal parts, for filling in blow holes, for repairing damage on containers, carriages and machine parts and for sealing pumps and pipes. The product can be used in mechanical and plant engineering, in equipment engineering, and in many other areas of industry.
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 HB 300 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.
