HYDROGENFLUORIDES OF AMINOSILANOLS AND THEIR USE

This invention relates to hydrogenfluorides of aminosilanols and their use. The hydrogenfluorides of aminosilanols are formed by the reaction of an aqueous solution of a fluorinated acid, preferably, hydrofluoric acid, with an aminoalkoxysilane. The hydrogenfluorides of aminosilanols are particularl...

Beschreibung
Zusammenfassung:	This invention relates to hydrogenfluorides of aminosilanols and their use. The hydrogenfluorides of aminosilanols are formed by the reaction of an aqueous solution of a fluorinated acid, preferably, hydrofluoric acid, with an aminoalkoxysilane. The hydrogenfluorides of aminosilanols are particularly useful in foundry binders, most particularly no-bake and cold-box phenolic urethane foundry binders.
