Each system consists of two components. After thoroughly mixing the two-component material system (A/B) in equal volume, the liquid mixture compounds can be processed for up to 24 hours by casting, spin-coating or other deposition methods. Due to the photo-sensitivity, the cross-linking (or curing) is initiated by UV-exposure. In contrast to generic PDMS, this allows almost full curing already at room temperature and significantly increases the curing speed (by factor of 100 and more). Furthermore, without the need of an additional thermal curing one can achieve a minimized shrinkage of 0.02%.
