WACKER POLYMER AL 08 is a polydimethylsiloxane with dimethoxysilyl end groups, appearing as a colorless to yellowish, clear liquid that is not water-miscible. It is used as a reactive polymer in moisture-reactive formulations for sealants, adhesives, and coatings (RTV-1 silicones) and is particularly suited for silicone sealants and specialized raw materials in sealant compounding.
