WEICON Easy-Mix HT 180 is a 2-component adhesive based on epoxy resin with high temperature resistance up to +180 °C (+356 °F); short-term up to +230 °C (+446 °F). The adhesive is highly viscous and stable which also makes it suitable for vertical applications. It is impact- and shock-resistant, has a long pot life, cures at room temperature and is machinable after curing. The adhesive is particularly suitable for the bonding of composite materials and metal and can be spot-welded while curing. Easy-Mix HT 180 can also be used on plastics, ceramics, glass, stone or wood and is suitable for adhesions where larger tolerances have to be bridged. Due to special fillers, it is possible to achieve a non-varying and reliable adhesive joint of at least 0.20 - 0.25 mm. The high temperature resistance enables the bonding of components, which are thermo-coated (powder-coated) after curing.
