Henkel now offers a significantly more durable alternative with its Terostat 285 sealant based on butyl rubber. Thanks to its completely new formulation, the sealant has built-in protection against damaging mold attack, which substantially reduces the need for later maintenance. In addition, the plastic butyl sealant has a self-welding capability, which allows it to fill cavities and compensate for tolerances, whereas classic rubber gaskets relax over time and lose their insulating properties. Irrespective of the design involved, Terostat 285 can be applied directly to the construction element – either extruded hot or as a pre-cut profile. The one-component sealant is highly tacky, has a high initial bond strength and is suitable for sealing nearly all metal and plastic materials.
