Lead-free paint coating for glass articles

The effect of binders on the quality of paint coatings formed on the basis of lead-free enamels and meeting the requirements of TU RB 100029049.030 has been studied. It has been established that enamel compositions can be prepared using a 20% solution of oxyterpene resin in turpentine and a 2% alcohol solution of Na-CMC grade 7MF. The use of an aqueous solution of dextrin as a binder leads to a deterioration in the quality of enamel coatings - a change in color, a loss of gloss, the appearance of a coke.
