Abstract RU 2289600 C2

FIELD: powder covers.

SUBSTANCE: invention relates to a powder cover composition and to a method for its preparing that forms cover with reduced luster after hardening. Composition comprises one or some cross-linked basic polymers: cross-linked polyester, cross-linked polyurethane, cross-linked acrylated polyether and their combinations, about from 5 to 60 wt.-%; cross-linked acrylic polymer with solidification point about from 40°C to 100°C, and about 0.1 to 10 wt.-% of one or some free-radical initiating agents. Additional reducing luster and improved smoothness can be obtained by addition spheroidal particles to the powder cover composition. Proposed compositions can be used for making covers on metallic backings, such as vehicle bodies and on nonmetallic backings, such as backings made of pressed wood materials with impregnation used for making table tops of different species.

EFFECT: improved and valuable properties of covers.
