The paper coating process
Paper coating is about printability or formation of specific surface layers for the intended use of the paper or paper-board. The various combinations of paper coating and printing technologies set highly specific requirements to the properties of the coated paper, requiring precisely formulated and applied coating chemicals.
Wax-dispersions are used for increased hydrophobicity, insolubilizers to improve tolerance to moisture at printing, defoamers to avoid formation of craters from air-bubbles and thereby improve surface smoothness, rheology modifiers for optimal runnability, biocides/preservation agents to prevent microbiological decay of coating components and microbial related problems at the coating application, as well as silicones for silicone coated papers.

Silicone - Used in more than you could ever imagine
Silicones have a positive effect on virtually every aspect of the paper industry. From pulp processing to paper finishing, label making, and paper recycling, silicones add value, improve productivity, and lessen the impact of paper-making operations on our environment.
