Characteristics
A black, high quality, strongly adhesive sealing band 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. Terostat-81 is self-welding. Higher temperature influence for a short time has
no adverse effect on quality and function.
Terostat-81 is aging resistant and is used for numerous application
purposes due to its excellent adhesion to cleaned metallic and non-metallic material
surfaces.
For industrial line production Terostat-81 is also available in 50
l hobbocks and can be applied by suitable equipment which can be heated.

Application areas
Terostat-81 is used for sealing and bonding in the areas listed
below:
– sealing, antiflutter and bonding of trim panels, protective and
covering trims, protective panels in the container and tank manufacture
– sealing of overlapping steel, steel sheet, aluminium, glass and
plastic constructions in the sheet fabricating industry, in the electrical industry or in
apparatus and machinery engineering
– bonding of PE foils, plastic sheets (e.g. EPDM) or parts in
plastic engineering and manufacture
– as protection against contact corrosion between steel and
nonferrous metals
– in the electrical industry for sealing and bedding parts with low
vibration.
Preparation for sealing
The surfaces to be sealed must be dry, free of oil, dust, grease
and other contaminants(e.g. release agents). On porous substrates we recommend the use of
Primer-188. Precheck compatibility with the substrates prior to use on plastics.
Application as sealing strip
Cut to the required length and then applied to the substrates to be
sealed and lightly pressed on. We recommend that removal of the release
paper or release foil occurs only after application, and pressing on. In that way, an
unwanted stretching of the strip during unrolling can be prevented, and the sealing band is
protected against contamination as well. After pulling off the release paper the counterpart is put
on and – if necessary – the entire part is mechanically fixed.
