FL 559 lacquer
SS 14147-80
Lacquer is used for coating of ready-made solid-drawn cans inner surface with evaporation method, rolling method for split cans and covers of tins and container glassware made of electrolytic and hot-dip tinning white sheet. Consumption for one layer according to solid residual – 3-4 g/m2. After polymerization at t = 180°Ñ within no more than 15 minutes becomes of glossy golden coating with high chemical resistance. It is used as a unit with R-30 thinner.
