For example, with elastomeric sealants, tear resistance measures how the test specimen resists the growth of any cuts when under tension, it is usually measured in N/mm 12 INTERNAL TEAR PROPAGATION RESISTANCE Tear progagation resistance of various elastic adhesives & sealants 15.0 14.0 13.0 12.0 11.0 10.0 9.0 8.0 N/mm 7.0 6.0 5.0 4.0 3.0 2.0 1.0 0.0 POLYSULPH.

In 2015 the development of the new organic acid-resistant sealant started. After mastering challenges in R&D (2 years) and scale-up (2 years), extensive internal and external testing (1 year) and passing the long certification and approval process (2 years) we are proud to present: Sikaflex®-403 Tank & Silo INTERNAL SIKAFLEX-403 TANK & SILO WHY DO WE NEED A NEW SEALANT FOR TANK & SILO’S Sikaflex®-403 Tank & Silo with significantly increased performance in: Durability Temperature resistance Movement capability Sikaflex®-403 Tank & Silo is synonym for sustainability in all regards: As sealant of biodigesters for carbon neutral biogas production As sealant to protect the ground water from leakage through the joints As more robust, reliable and long-lasting solution INTERNAL SIKAFLEX-403 TANK & SILO APPLICATIONS AND CUSTOMERS – AGRICULTURE & INDUSTRY Segmented & bolted steel tank systems Prefab concrete element solutions System providers: Permastore, Stallkamp, Engineering and design offices Schumann Tank, Henze etc. Concrete precasters (often Sika customers) Installation contractors Installation and joint sealant contractors We are market leaders in providing sealants for such Here we see big potential to grow tanks and we supply all the major payers globally Countless joints that are exposed to organic acids – choose Sikaflex®-403 Tank & Silo INTERNAL SIKAFLEX-403 TANK & SILO WHY IS PU THE PREFERRED TECHNOLOGY? Application properties: Long open time: Essential for segmented steel tank construction Dedicated rheology: Easy to extrude, non-sag and easy to apply and to smooth Curing properties: PU is the only technology that will reliably through cure in the segmented steel tank application. The sealant lies between the steel plates and has only limited access to humidity. The released CO2 will not prevent the polymerization. STP/MS or silicones release chemical substances (e.g., methanol) during curing. If these substances cannot be released the reaction is stopped. In the worst case the reaction is reverted, and the sealant starts do depolymerize Mechanical properties: The unique microstructure of polyurethane sealants consists of with hard and soft segments making the material strong, tough and resistant and at the same time elastic and flexible. There are the key properties for durable and reliable tight joints.
