When it comes to transparency of adhesives and sealants, AEROSIL® is crucial.
AEROSIL® fumed silica is used successfully in transparent adhesives and sealants as thixotrope and reinforcing agent. Due to its fine particle size, AEROSIL® fumed silica leaves clear adhesives and sealants more transparent than some other particulate additives do. Especially AEROSIL® grades with small primary particle sizes resp. high specific surface areas like AEROSIL® 200, AEROSIL® 300, AEROSIL® 380 or AEROSIL® R 974, AEROSIL® R 106, AEROSIL® R 805 or AEROSIL® R 812 S are recommended for transparent adhesives and sealant systems.
