Polymer ST 75

Polymer ST 75 by Evonik is a phthalate-free silane-terminated polymer. It is suitable for applications where a balanced stress-strain behavior is required as in transport and assembly applications. It is particularly suitable for applications where change of dimensions based on temperature changes occur. Due to its high elastic recovery Polymer ST 75 shows excellent adhesion to aluminum, steel, plastics and fiber reinforced composites. It is used in assembly of super structural parts, bumpers. For assembly applications, adhesives must be processed quickly and provide a rapid strength build-up. In these cases, it is a suitable solution as its stress-strain behavior can be tuned to the application needs. It has a shelf life of 9 months.
