Description:
COFOMEGRA Additive Oil for Magnesium is a fluid formulated for the magnesium plate photo-etching process. The product is designed to protect non-image areas during etching, ensuring clear and sharp edges on the finished plates. The additive is used in combination with nitric acid (42° Baume) and water to prepare the etching bath. The recommended concentration in the bath is between 4% and 5% by volume. The product offers protective properties that allow for a lower dosage compared to standard market recommendations, resulting in 20% oil savings with cost and pollution reductions. The etching bath temperature must be maintained between 28°C and 32°C during operation. Paddle speed and depth are specified parameters for achieving optimal etching results with this fluid. This additive is part of the consumables range for industrial photochemical machining processes.
Overview:
| Bath Temperature | 28°C to 32°C (4 to 6°C lower than standard operating temperatures) |
| Paddle Speed | 500 ± 50 rpm (subject to determination via etching tests) |
| Paddle Depth | 9 mm (3/8 inch) – must be uniform across all paddles |
| Nitric Acid (42° Baume) | 20 to 22% by volume |
| Additive Oil | 4 to 5% by volume (4% sufficient due to high protection) |
| Water | Approximately 75% by volume |
