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 INTERN TEAR PROPAGATION Tear progagation resistance of various elastic RESISTANCE 15. 0 adhesives & sealants 14. 0 13. 0 12. 0 11. 0 mm 10.

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 INTERN 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 INTERN SIKAFLEX-403 TANK & APPLICATIONS AND CUSTOMERS – AGRICULTURE SILO & INDUSTRY Segmented & bolted steel tank Prefab concrete element solutions systems System providers: Permastore, Engineering and design offices Stallkamp, Schumann Tank, Concrete precasters (often Sika Henze etc. customers) Installation contractors Installation and joint sealant We are market leaders in providing contractors Here we see big potential sealants for such to grow tanks and we supply all the major payers Countless globally joints that are exposed to organic acids – choose Sikaflex®-403 Tank & Silo INTERN SIKAFLEX-403 TANK & WHY IS PU THE PREFERRED TECHNOLOGY? SILO 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 INTERN SIKAFLEX-403 TANK & SILO COMPETITORS There are only few competitors: SABA Ecoseal AC: STP-based, for biogas plants SABA Ecoseal HM: STP-based for joints with microbiological loads, drinking water, sewage treatment water Manus / ManusBond in Americas Local suppliers in Asia e.g. China (Guibao, Huagui, etc…) INTERN CUSTOMERS PAINS POINT AND OPPORTUNITY FOR US No competitors No competitors Competitors provide technical service provide comprehensive test products so far certificate was not good German approval for digestion areas for agriculture use. …to get this approval was: 100 kCHF invest for testing 4 years of testing and evaluation INTERN SIKAFLEX-403 TANK & SILO COMPARISON TO SIKAFLEX® TS PLUS – ADVANTAGES Properties Sikaflex TS Sikaflex-403 Tank & Silo plus 20 HM (EXT-INT CC) Movement capability 12,5 HM New: CE marking, floor joints EN15651-4 PW No Yes Over drivable acc.
