ALKOXYSILOXANES, THEIR PREPARATION AND USE AS ANTIFOAMING AGENTS FOR CURABLE RESINS AND PLASTISOLS

Alkoxysiloxanes of the general formula are disclosed wherein R1 is methyl or and/or the sum of the units a being 0 to 100, the sum of the units b being 0 to 15, with the proviso that the ratio of methyl to alkoxy groups in R1 is less than 50:1, and that b>/=1 when a=0 and a>/=5 when b=0. The c...

Beschreibung
Zusammenfassung:	Alkoxysiloxanes of the general formula are disclosed wherein R1 is methyl or and/or the sum of the units a being 0 to 100, the sum of the units b being 0 to 15, with the proviso that the ratio of methyl to alkoxy groups in R1 is less than 50:1, and that b>/=1 when a=0 and a>/=5 when b=0. The compounds may be synthesized by known methods from halogen- or alkoxysiloxanes, the alkoxy group of which has 1 to 4 carbon atoms. The compounds are effective deaerating agents for curable resins and plastisols. The invention is also directed to compositions containing the novel deaerating compounds as well as to methods for deaerating coating systems.
