GENIOSIL^® XM 25

GENIOSIL^® XM 25 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 trimethoxysilyl group attached to the organic backbone. It hydrolyzes in the presence of moisture to finally form a stable siloxane network initiated by heavy metal or strong amine catalysis. Formulations are characterized by the following advantages:

•  simple compounding with conventional auxiliaries
•  plasticizer free if desirable
•  modification to achieve lower Modulus
•  very good elastic recovery and high elasticity
•  rapid curing
•  broad adhesion profile
