Lead-Free Paint Coatings for Glass Articles

The effect of binders on the quality of paint coatings based on lead-free enamels and meeting the requirements of standard TU RB 100029049.030 is considered. It is established that enamel compositions can be prepared using 20% solution of oxyterpene resin in turpentine and 2% alcoholic solution of Na-carboxymethyl cellulose of grade 7MF. The use of an aqueous solution of dextrin as a binder deteriorates the quality of enamel coatings: it produces color modifications, loss of luster, and formation of crackle.
