Features and benefits

High-quality butyl sealing compound with powerful adhesion and plasto-elastic properties.



TEROSON® RB 81 is a high quality, strongly adhesive sealing tape based on butyl rubber with plasto-elastic properties. The particularly strong tackiness provides a firm lamination between the contact surfaces and, therefore, a reliable sealing effect. RB 81 is self-welding. Higher temperature influence for a short time has no adverse effect on quality and function.
