Coating and method for producing coated paper or cardboard

A method for producing coated paper or cardboard, comprising the steps of:

• producing a coating pigment in an aqueous dispersion;
• degasifying said aqueous dispersion of said coating pigment;
• mixing at least one thickener and at least one surfactant into said aqueous dispersion of said coating pigment under air-tight conditions after said degasifying step;
• adding at least one binding agent;
• and
• applying said coating pigment in said aqueous dispersion to one of a moving paper line and a cardboard line in a free-falling curtain.

A method for producing coated paper or cardboard, comprising the steps of:

• producing a coating, said coating including
• at least one pigment in an aqueous dispersion and having a pigment percentage;
• at least one binding agent in a first portion of at least 7 percent by weight, said first portion depending on said pigment percentage;
• at least one thickener in a second portion of approximately between 0.05 to 0.5 percent by weight, said second portion depending on said pigment percentage;
• at least one surfactant in a third portion of at least 0.1 percent by weight, said third portion depending on said pigment percentage;
• a solid content of approximately between 50 to 70 percent by weight;
• said coating having a viscosity of no greater than 1000 mPas (Brookfield 100 UPM, 20° C.);
• and
• applying said coating to a moving line of one of the paper and the cardboard by way of a curtain-coater in a free-falling curtain.
