GENIOSIL STP-E 30

GENIOSIL® STP-E30 is a polyether-based silane-terminated polymer suitable as a binder in moisture curing formulations. It is a clear liquid with a slight but characteristic odor and differs to conventional silylated polymers due to its high reactivity.This is a direct consequence of the structural proximity of the nitrogen atom to the silicon atom in the dimethoxy(methyl)silyl methylcarbamate group (alpha-effect). It hydrolyzes in the presence of moisture to finally form a stable siloxane network initiated by mild catalysis as opposed to heavy metal ions. Formulations are characterized by thefollowing advantages:• simple compounding with conventional auxiliaries• plasticizer free if desirable• tin free• transparent systems• good mechanics• rapid curing• broad adhesion profile• long shelf life
