Abstract
A highly storage-stable organopolysiloxane composition capable of the long-term retention of its surface-modifying activities, such as antistatic and anticlouding activities is disclosed. The composition comprises a first polyoxyalkylene-functional diorganopolysiloxane that is free of amino, carboxyl, and epoxy groups, a second polyoxyalkylene-functional diorganopolysiloxane that contains an amino-functional organic group, and water.
Claims18
A storage-stable organopolysiloxane composition comprising:
- (A) a first polyoxyalkylene-functional diorganopolysiloxane that is free of amino, carboxyl, and epoxy groups,
- (B) a second polyoxyalkylene-ftnctional diorganopolysiloxane, with the proviso that each molecule of component (B) comprises at least one polyoxyalkylene group and at least one amino-functional organic group, and
- (C) water.
A method for preparing a storage stable organopolysiloxane composition, the method comprising:
- 1) mixing components (A) and (B), and thereafter
- 2) combining the product of step 1) with component (C) by a method selected from the group consisting of dispersing to homogeneity and dissolving;
- wherein
- component (A) is a first polyoxyalkylene-functional diorganopolysiloxane that is free of amino, carboxyl, and epoxy groups,
- component (B) is a second polyoxyalkylene-functional diorganopolysiloxane, with the proviso that each molecule of component (B) comprises at least one polyoxyalkylene group and at least one amino-functional organic group, and component (C) is water.
A method for preparing a storage stable organopolysiloxane composition, the method comprising
- 1) combining component (A) with (C) water,
- 2) combining component (B) with (C) water, and thereafter
- 3) intermixing the product of step 1) and the product of step 2);
- wherein component (A) is a first polyoxyalkylene-functional diorganopolysiloxane that is free of amino, carboxyl, and epoxy groups and component (B) is a second polyoxyalkylene-functional diorganopolysiloxane, with the proviso that each molecule of component (B) comprises at least one polyoxyalkylene group and at least one amino-functional organic group.
