Fine-etching crystals 3207, 220 g bag
13 L 277
Fine-etching crystals, type Seno 3207. Modern, versatile and clean etching agent with especially even action for high contrast, low under-etching and unproblematic neutralization. Contrary to ammonium persulfate, this extraordinarily fine powder dissolves perfectly in water and does not crystallize even at 0 °C. The cold solution is only slightly aggressive. Splashes and spills can be rinsed off easily with water. This fine-etching crystal is an ideal alternative to iron-III chloride. Absolutely free of ammonium; Operating temperatures: 30 to 40 °C, does not crystallize. Can be used many times over for all conventional processes. Etching machines with a high throughput rate should be equipped with a cooling system. The etching speed (depends on the technique, temperature and copper content of the solution) is 30 to 8.0 my/min with an average copper transfer of 30 to 40 g/l. The optimal concentration is 200 to 240 g/l. This agent is intended for technical use only. It must be appropriately used, stored and disposed of. Work material regulations should be observed. Type : 3207, 220 g bag
