<p>Aqueous, fine particle to optically clear, thermally and mechanically stable silicone emulsions contain, in relation to the total emulsions, 3 to 25 % by weight of a water-soluble emulsifier (a), 0.1 to 84 % by weight of an aminoalkyl-substituted polysiloxane (b) (amine number at least 0.1), which may be present at least partially in salt form and which may be replaced by up to 70 % by weight of other polysiloxanes (emulsifier/silicone ratio at least 1,2 to 10), up to 3 % by weight of a low molecular weight weak acid (c) and at least 5 % by weight of water (d), whereby the sum of (a), (b), (c) and (d) is equal to 100 % by weight. Also described are a process for manufacturing these emulsions and the use thereof. The silicone emulsions according to the invention possess outstanding thermal stability.</p> |
