    摘要: A reaction product of a tetraalkoxysilane or a silicate oligomer obtained by the partial hydrolysis and dehydrating polycondensation of the same with an amino alcohol having one or two hydroxyl groups. It is suitable for the dehydration of a moisture of about several hundreds of ppm, and especially suitable for use as a dehydrating agent for the raw materials employed for the preparation of a urethane resin and an epoxy resin, because it produces an amino alcohol by the dehydration.
