Abstract
Abstract The invention relates to a one-component formulation, containing an additive which envelops paint particles, for precipitating, detackifying and coagulating underseal based on waxes, wax-like plastics and plastics dispersions and also synthetic resin paints in wet paint mist separators of paint-spraying installations, a sedimenting paint sludge being obtained, which formulation comprises, as the additive, an aqueous suspension of hydrated marble lime. The invention also relates to the use of the above one-component formulation for precipitating, detackifying and coagulating underseal based on waxes, wax-like plastics and plastics dispersions and also synthetic resin paints in wet separators of paint-spraying installations, a sedimemting paint sludge being obtained.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
The one-component formulation for precipitating, detackifying and coagulating underseal based on wax, wax-like plastic and plastic dispersions, and synthetic resin paint in an aqueous mixture to obtain a sedimenting paint sludge comprising an additive which envelops paint particles, said additive being an aqueous suspension of hydrated marble lime, wherein the suspension of hydrated marble lime contains a mixture of a blend containing cellulose and montmorillonite, smectite or combination thereof, and the condensation product of sodium salts of naphthalenesulfonic acid.
Claim 2
Dependent Claim
79 words
The one-component formulation for precipitating, detackifying and coagulating underseal based on wax, wax-like plastic and plastic dispersions, and synthetic resin paint in an aqueous mixture to obtain a sedimenting paint sludge comprising an additive which envelops paint particles, said additive being an aqueous suspension of hydrated marble lime, wherein the suspension of hydrated marble lime contains a mixture of a blend containing cellulose and montmorillonite, smectite or combination thereof, and the condensation product of sodium salts of naphthalenesulfonic acid.
Claim 3
Dependent Claim
69 words
The one-component formulation for precipitating, detackifying and coagulating underseal based on wax, wax-like plastic and plastic dispersions, and synthetic resin paint in an aqueous mixture to obtain a sedimenting paint sludge comprising an additive which envelops paint particles, said additive being an aqueous suspension of hydrated marble lime, wherein the aqueous suspension of hydrated marble lime further contains a low-foaming, alkali-resistant, surface-action wetting agent based on fatty alcohol alkoxylate.
Claim 4
Dependent Claim
69 words
The one-component formulation for precipitating, detackifying and coagulating underseal based on wax, wax-like plastic and plastic dispersions, and synthetic resin paint in an aqueous mixture to obtain a sedimenting paint sludge comprising an additive which envelops paint particles, said additive being an aqueous suspension of hydrated marble lime, wherein the aqueous suspension of hydrated marble lime further contains a low-foaming, alkali-resistant, surface-action wetting agent based on fatty alcohol alkoxylate.
Claim 5
Dependent Claim
66 words
