THIXOTROPIC CYANOACRYLATE COMPOSITIONS

Cyanoacrylate compositions which employ fumed silicas treated with polydimethylsiloxane or trialkoxyalkyl silane are stable and exhibit an unexpectedly high thixotropic ratio. Such compositions are useful in adhesive applications or, when stabilized so as to prevent polymerization in contact with mo...

Zusammenfassung:	Cyanoacrylate compositions which employ fumed silicas treated with polydimethylsiloxane or trialkoxyalkyl silane are stable and exhibit an unexpectedly high thixotropic ratio. Such compositions are useful in adhesive applications or, when stabilized so as to prevent polymerization in contact with moisture, in latent fingerprint developing applications. Des compositions à base de cyanoacrylate utilisant des silices fumées traitées à l'aide de polydiméthylsiloxane ou de trialkoxyalkylsilane sont stables et présentent un rapport thixotropique étonnamment élevé. De telles compositons sont utiles dans des applications en tant qu'adhésifs ou, lorsqu'elles sont stabilisées de manière à empêcher la polymérisation en contact avec l'humidité, dans des applications de développement d'empreintes digitales latentes.
