MODIFYING ADDITIVE FOR WATER-BASED POLYORGANOSILOXANE POLYMER AND COPOLYMER OF BUTADIENE WITH STYRENE Russian patent published in 2010 - IPC C09D7/04 C09D183/10 

FIELD: chemistry.

SUBSTANCE: invention relates to modifying additives for making protective polymer coatings based on water-based polyorganosiloxane polymer and a copolymer of butadiene and styrene. Proposed is a modifying additive for water-based polyorganosilixane polymer and a copolymer of butadiene with styrene containing the following (in wt %): 60-70% solution of epoxyaminorubber adduct in a mixture of ethylglycolacetate and butanol, where the adduct is modified with melamineformaldehyde resin (11.0-14.0); water and additionally acetic or phosphoric acid (0.1-1.5), as well as 80% solution of diene epoxide resin (1.0-12.5) in a mixture of xylene and acetylcellosolve, taken in ratio of 5:1.

EFFECT: design of a modifying additive with high stability for not less than 6 months from the date of manufacture.
