TECHNOLOGY OF COATING OF PRINTING SURFACES
In order to increase the period of use of the tables, as well as to protect them from contamination, diluted solutions of polymers are also applied to the paper surface. to prepare such solutions, 2-3 g of crushed polymer (plexiglass, polystyrene) are dissolved in 100 ml of a suitable organic solvent (benzene, carbon tetrachloride, ethyl acetate, etc.). The solution is applied several times, each time waiting for the previous layer to dry completely. Cover the product in an open atmosphere or in a fume hood to avoid poisoning with volatile solvents.
