ABSTRACT:
An aqueous silicone emulsion which crosslinks by a Michael addition reaction, yielding a cured composition upon removal of the water has been prepared. The aqueous silicone emulsion comprises the product formed by mixing an organosiloxane polymer containing at least two Michael acceptor groups per organosiloxane molecule, water, a surfactant and an effective amount of a crosslinker having sufficient reactive hydrogens of a Michael donor per crosslinker molecule. The invention also describes a method for making these silicone emulsions.
