FIELD: chemistry.
SUBSTANCE: coating means is proposed, containing: A) 1 to 30 wt % of prepolymer, obtained by radical polymerization of mixture comprising of: A1) 1 to 10 wt % at least one sulphurous compound having at least three thiol groups, and A2) 90 to 99 wt % alkyl(meth)acrylates; B) 0.2 to 10 wt % at least one fluoralkyl(meth)acrylate having 3 to 30 carbon atoms in alcohol residue and including 6 to 61 fluorine atoms; C) 20 to 80 wt % polyfunctional (meth)acrylates; D) 0.01 to 10 wt % at least one initiator; E) 2 to 75 wt % at least one thinner; and F) 0 to 40 wt % common additives. Also, formed piece including polymer substrate and scratch-proof covering is proposed, as well as method for its production that consist in coating means applying on polymer substrate followed by hardening.
EFFECT: scratch-proof covering with dirt-repellant effect.
