Innovative High-Temperature Product from DENSO

In the past, the composition of cold-processed corrosion protection tapes meant that they were of limited use at extremely high temperatures.

With its new product DENSOLEN®-AS40 HT, DENSO Group Germany is setting a new global standard. Used in combination with a new primer, the cold-processed, butyl rubber-based corrosion protection tape DENSOLEN®-AS40 HT achieves excellent performances. Even at extremely high operating temperatures of up to +100°C (+212°F), the product guarantees reliable protection against corrosive media and mechanical loads after just one wrapping process. The product satisfies the requirements of the ISO 21809-3, type 12A-3 standard after just one wrapping process; a second wrap meets the class C80 requirements of EN 12068 and DIN 30672. DENSOLEN®-AS40 HT boasts an exceptionally high resistance to mechanical loads and is easy to apply thanks to its highly tear-resistant and adaptable carrier film.

DENSOLEN®-AS40 HT has been developed over 5 years – a process that was not without challenges, as the product had to satisfy a number of different requirements. DENSOLEN®-AS40 HT is applied by hand or using a DENSOMAT® wrapping device, which means that it is also suitable for large-scale use for rehabilitations or complete coatings on oil, gas and water pipelines. The product is outstanding at exceptionally high operating temperatures, such as those in power stations, refineries and pipeline stations. DENSOLEN®-AS40 HT is also ideal for applications at high ambient temperatures, in areas such as Central Asia, the Middle East and Central America.
