N.-O. Bergh. Binders for paper coating: starches, proteins and latices. In The Fundamentals of Papermaking Materials, Trans. of the XIth Fund. Res. Symp. Cambridge, 1997, (C.F. Baker, ed.), pp 139–207, FRC, Manchester, 2018.


There are many chemicals, both natural and synthetic, which are used for surface application of paper and board. In this overview shall the use of starch and protein be discussed as representatives of products arriving from renewable resources and the use of latex as there presentative of products arriving from chemical synthesis. Starch is used for coating of paper both in combination of pigments- coating colours, and for surface application in size press, film press or other application units. As the influence of the starch properties -both from the chemical and from viscosity point of view is of great importance for the runnability of the machines and the paper quality, will starch quality be discussed to a great extend. The influence of starch quality on the rheological properties of coating colours of the different types of coating colours will there after be discussed. Protein and latex are mainly used as binders in coating colours. The influence of the chemical and physical properties of these binders on the pigment- binder interaction and the subsequent paper properties will be discussed as far it is possible from a general point of view.
