ONE-COMPONENT SYSTEMS FOR COVERING Russian patent published in 2009 - IPC C08G18/10 C08G18/08 C09D5/00 C09D175/04 C03C25/26 

FIELD: chemistry.

SUBSTANCE: invention relates to water one-component systems for covering, which are used in glue compositions, in sealants, lacquers and size. Said systems contain (I) at least one polyurethane (A), which contains chemically bound hydrophilic groups, and, in which groups containing active by Tzerevitinov hydrogen atoms are present in amount from 0 to 0.53 mmole/g in terms of relative content of non-voletile dispersion components, (II) at least one blocked polyisocyanate (B), which does not contain hydrophilic groups, and (III) water, weight component ratio between components A and B being chosen in such way that content of blocked isocyanate constitutes from 0.01 to 1.0 mole per 100 g of hard resin. Also described are method of obtaining said systems, their application in sizes for glass fibre, method of obtaining from them covering on carriers, as well as carriers with applied on them preparations for covering, containing systems for covering of composition described above.

EFFECT: obtaining system which ensures stability in storage, reduced water-absorption, higher water-resistance and improved adhesive strength in wet state.
