TECO ADDHESIVE SYSTEM
TECO ADDHESIVE SYSTEMCTS offers you an integrated 4-component bonding system for the assembly bonding of tunnel segment gaskets. It consists of of a spraying system, assembly adhesive cleaning agent and lubricant.
TECO-BOND-PLUS3was developed especially for bonding elastomeric sealing profiles to concrete surfaces. The styrene-rubber adhesive is characterized by high initial strength and very good long-term adhesion.
LUBRICANT GM-95Shortly before installing the tunnel segments, the sealing frames on the longitudinal joint sides must be lubricated with a suitable lubricant to reduce the surface friction forces. This applies in particular to the so-called "keystone". Cordes GM-95 is an ideal product for this application.
CTS ANCHOR SHA combined self-healing compression seal (SH = self-healing) with a separate insertable round cord made of water-swellable (hydrophilic) material as an integrated version for glueless instal-lation directly into the segment mold.
CTS ANCHORA "mono-compression seal" integrated into the tunnel segments for adhesiveless & direct installation into the segment mold.
CTS SHA combined self-healing compression seal (SH = self-healing) with a separately insertable round cord made of water-swellable (hydrophilic) material
CTS STANDARDA classic "mono-compression seal" for installation on the tunnel segments using the conventional contact and wet-bed bonding methods.
