Self drying liquid photosensitive anti-corrosion and anti electroplating ink

liquid photosensitive anti-corrosion ink lpr-812 is widely used in the etching of precision metal graphics. It has the characteristics of high resolution and strong corrosion resistance. However, the photosensitive anti-corrosion inks sold on the market at present need to be pre dried in a 70~90 ℃ hot air circulation oven for 30~50 minutes, and the surface can be photosensitive and developed after drying. For double-sided plates, it needs to be baked twice. In use, we often encounter the following problems: (1) baking is not dry, which continuously enhances customer satisfaction, resulting in sticking negatives; (2) Excessive baking, photosensitive film is not photosensitive or difficult to develop; (3) Due to the different baking time on both sides of the double-sided board, the photosensitive and developing conditions pose a certain resistance to the use and implementation; (4) The photosensitive layer on the oversized metal plate cannot be dried. With the explosion of the field of new energy vehicles, enterprises with poor equipment conditions or no air blowing in the oven have more problems in use and lower yield

Hangzhou Kewang special ink company recently introduced lpr-812 self drying liquid photosensitive anti-corrosion ink to users, which has excellent photosensitivity and corrosion resistance. The outstanding feature is that after printing or spraying, it can be completely dried at room temperature (25~30 ℃) for more than 2 hours, and the second side printing or photosensitivity, development and etching can be carried out without baking, which greatly facilitates users. Process: plate printing (200~300 mesh) or double-sided spraying → natural DuPont Viton fluororubber has won awards for its unique combination of high-temperature performance and chemical corrosion resistance. Drying (about 2 h/light proof) → printing the second side → natural drying → photosensitivity → development (1% sodium carbonate aqueous solution) → etching (acid chemical corrosion or electric etching) or electroplating → deinking (1% - 3% sodium hydroxide)
