The preparation AKRATAM AS 01.4 is a binding agent for the processes of coating paper and cardboard. It is an aqueous dispersion of styrene-acrylic polymer. Does not contain plasticizers, solvents, emulsifiers based on ethoxylated alkylphenols (without APEO).

Application area:

Dispersion is recommended as a binder for coating slurries, and also as an additional co-binder for the purpose of:

  • increase the strength characteristics of coating layers;
  • preparation of pigment pastes for single and double-layer coating of paper and cardboard;
  • for priming the layers before further processing

It can be used instead of styrene butadiene latex for coated cardboard, coated paper with a double coating on a cellulose base, as well as paper LWC.

Main advantages:

  • provides a high degree of gloss and smoothness to the paper coating
  • demonstrates excellent processability in use (low foam, does not form a stump on the equipment, does not have a sharp unpleasant odor)
  • provides high rates of plucking
  • Excellent for color pigment coatings, has a high rate of color perception
  • stable at storage
  • has antibacterial protection

ACRATS AS 01.4 is positively tested in comparison with butadiene-styrene commercial latex in coating compositions:

  • meets the basic technical requirements for coatings on coating devices "varibar" and "air scraper"
  • creates a high level of printing and technical properties of coated cardboard,
  • has an advantage in terms of gloss and kraskoverchestviya.

Akratam AS 01.4 has an advantage in terms of the indicator of kraskoobrapriyatie - 1.02 versus 0.7-0.98, in terms of the degree of smoothness - 180 seconds and the gloss of 30-37%.

Coated cardboard with a double coating. The replacement of commercial butadiene-styrene latex with AS01.4 dispersion in the coating composition showed an increase in the strength of the coated cardboard surface (even after reducing the binder content by 2 parts by weight). At the same time, an increase in the surface finish (gloss), kraskoospriyatiya, whiteness and lightfastness of the coating is achieved.

Coated paper. The use of AS 01.4 in the coated composition instead of the commercial butadiene-styrene and styrene-acrylic dispersions showed an increase in the degree of finishing of the paper and an improvement in the color perception.

Lightweight LWC paper. The production of LWC paper with the use of a coating composition, Akratam AS 01.4, has an advantage over all standardized paper values ​​in comparison with commercial dispersion.

Styrene-acrylic dispersion Akratam AS 01.4 PJSC Pigment is a high-tech binder and is recommended for the production of coated papers and paperboard with double application, as well as for the production of LWC paper.
