Self-drying liquid photosensitive resisting plating ink

Liquid photosensitive resist ink LPR-812 is widely used in the etching of precision metal patterns. With high resolution, strong corrosion resistance, but currently on the market for sale of photosensitive resist ink, are required to be pre-baked in a 70-90 °C thermal cycle oven 30 ~ 50min, the surface can be exposed to light after drying, development. For the double panel, it is necessary to bake twice. When it is used, the following troubles are often encountered: (1) baking does not result in sticking to the film; (2) overbaking, photosensitivity is not sensitive to light or development is difficult; (3) double panels are trapped on both sides The baking time is not the same, resulting in inconsistent photoreceptor and developing conditions; (4) The photosensitive layer on the large-size metal plate cannot be dried. For enterprises with poor equipment conditions or without an air blow, the problem is more when used and the yield is lower.
Hangzhou Kewang Specialty Ink Co., Ltd. recently introduced LPR-812 white dry liquid photosensitive resist ink to users. With excellent photographic performance and corrosion resistance, the outstanding feature lies in the user's screen printing or spraying, after placing at room temperature (25-30 °C) for more than 2h to completely dry. The second side printing or sensitization, development and etching can be performed without baking, which greatly facilitates the user. Process: screen printing (200-300 mesh) or double-sided spraying a naturally dry (about 2 h / dark) a printed second side of a natural dry a photosensitive one development (1 ‰ sodium carbonate aqueous solution) an etching (acid Chemical etching or electroetching) or plating to remove ink (1% to 3% sodium hydroxide).
