GENIOSIL® XM 25

Technical DataSheet | Supplied by Wacker

GENIOSIL® XM 25 by Wacker is a gamma-silane-terminated polyether. Acts as a reactive plasticizer since it does not alter the mechanical strength of the cured material. It has one silane group at one of their chain ends and so it crosslinks only at that end. Used in formulation of low-modulus sealants with exceptionally high elastic recovery. Potential applications include sealants for expansion joints in buildings made of industrially prefabricated concrete parts and for connection joints between window frames and walls. Can be blended with other silane-terminated polymers in the desired ratio. On curing, the new polymers are firmly integrated into the resulting three-dimensional polymer network, reducing the crosslink density. This leads to a relatively wide-meshed network. GENIOSIL® XM 25 not only adheres to concrete, wood, aluminum and glass, but also to low-energy surfaces such as polyvinyl chloride (PVC), polystyrene (PS) and cured ethylene propylene diene monomer (EPDM) rubber without prior pre-treatment of these substrates.
