Two types of pastes were used in Poland, based on nitrocellulose and methacrylate gum. Barium, strontium and calcium carbonates were mixed in binder. Appropriate diluents and plasticizers were also added. Thus, depending on the used binder, the products of decomposition during the formation of the cathode were: carbon dioxide, nitrogen, water vapor or carbon dioxide, water vapor. Some carbon monoxide may have been formed as well. In Polish picture tubes, only getters based on a metallic barium were used.
In the residual gases, methane appeared as the dominant gas in the pumping out and gettered picture tube.
