Fixing the four-metre bronze-effect sundial that graces the wall of the new Bridport Community Hospital, Dorset, required some intensive care - stainless steel Bighead bonding fasteners.
As of 2007, trains will whisk passengers and rail cargo through the new Lotschberg base tunnel at about 200 kilometres per hour.
The latest technology for tunnel and rolling stock construction, precision work - and Collano specialty adhesives ensure safe travel through the mountain, said the company.
Signalling and communications are handled by equipment placed in 136 climatised control units situated at intervals along the tunnel.
The enclosures protect sensitive electronic circuitry against the harsh tunnel environment where temperatures can exceed 35 degrees C and relative humidity can rise to more than 80 per cent.
The control units must also withstand pressure waves, vibration and fire.
The walls of the control unit enclosures are a NiCr steel sandwich construction designed especially for the tunnel project.
FHS E Frech-Hoch AG, the manufacturer of the sandwich elements, selected Collano A8 7110 to bond the elements.
With a mixing and metering system, the adhesive is applied to the pre-cleaned CNS panels and then uniformly distributed.
Subsequently, rock wool panels, Duripanel elements, and CNS spacers are inserted and bonded with the second CNS panel.
The A8 7110 adhesive, developed especially for this application, features what Collano claimed as excellent adhesion, whilst being flame-retardant (fire class 5.3 Switzerland), remaining elastic, and resistant to moisture, vibrations and temperature fluctuations.
Collano is based in Switzerland and has subsidiaries in Germany, France and the United States.
It generates revenues of CHF 100 million and employs 300 people.
