GENIOSIL® XL 70
GENIOSIL® XL 70 is a clear, colorless liquid.
GENIOSIL® XL 70 is an alkoxyarylsilane. In the presence of moisture silanols are formed by hydrolysis (methanol is released), which can then react to form siloxanes.
In silane-crosslinking formulations, (e.g. silane-terminated polyethers , polyurethanes or polysiloxanes), GENIOSIL® XL 70 is mixed into the formulation as an additive to prevent premature crosslinking due to trace moisture. Processing is effected by means of standard mixing methods (e.g. paddle agitator, dissolver, kneader). GENIOSIL® XL 70 may be added before or during incorporation of the reactive polymer. The amount added will depend on the water content and pretreatment of the components
GENIOSIL® XL 70 is used as water scavenger during the production of silane-crosslinking adhesive and sealant formulations. In particular the brandnew water scavenger exhibits a high flash point and is virtually odorless.
