摘要:
The present invention encompasses a surface treatment composition which comprises a polyorganosiloxane fluid-silicone resin mixture and a carrier. The polyorganosiloxane fluid-silicone resin mixture comprises about 2% to about 95%, by weight of the mixture, of one or more polyorganosiloxane fluid compounds; from about 1% to about 10%, by weight of the mixture, of one or more silicone resin, a protonation agent, at least about 5%, by weight of the mixture; of water; and optionally, less than about 5%, by weight of the mixture, of an emulsifier.

摘要:
Storage stable polyorganosiloxane-silicone resin mixtures contain: 1) 100 parts by weight of one or more liquid aminoalkyl-containing polyorganosiloxanes containing at least 80 mol % of units selected from units of the formulae Ia, Ib, II and III R12SiO(4-a-b)/2 (Ia), R1aR2bSiO(4-a-b)/2 (Ib), R33SiO(1/2) (II), R32R4SiO(1/2) (III), wherein, in the polydimethylsiloxanes, the average ratio of the sum of units of the formulae Ia and Ib to the sum of units of the formulae II and III is in the range from 0.5 to 500, the average ratio of units II to III in the range of 1.86 to 100, and the polydimethylsiloxanes have an average amine number of ≧0.01 mequiv/g, 2) at least 1 part by weight of one or more silicone resins, and 3) at most 5 parts by weight of water.
摘要:
Aqueous emulsions of organopolysiloxanes functionalized with a limited amount of aminoalkyl-functional end groups and silicone resins are storage stable, yet capable of adequate crosslinking upon application to substances to be hydrophobicized.

摘要:
Fully acylated hydroxyl-terminated organopolysiloxanes bearing pendant aminoalkyl groups are easily prepared by reacting a hydroxyl-terminated, aminoalkyl organopolysiloxane with a carboxylic anhydride in stoichiometric amount relative to amino groups, in the presence of at least one emulsifier.
