What kind of photosensitive glue is good for dry small fonts?

Printing small print requires selecting appropriate gauze and photosensitive glue, and then testing the exposure time. If the mesh size exceeds 350 meshes, it is necessary to choose a multi-curing photosensitive adhesive with high resolution to meet the resolution requirements. Only a proper exposure time can produce a clear image. Exposure time is too long, it is difficult to wash away fine lines. If the exposure time is too short, degumming will occur during washing.

In view of this, AD20 from Murakami, Japan or Kotter1711from Switzerland are recommended as photosensitive adhesives.

Attachment: Photosensitive adhesive brand and its product characteristics

1. What is photosensitive glue: photosensitive glue is also called photosensitive latex, and photosensitive film (also called film film) is a commonly used photosensitive material at present. Photosensitive adhesive is used for direct plate making, which is generally divided into single-liquid type and double-liquid type: single-liquid type photosensitive adhesive, which has been mixed with latex during production and can be used without preparation. Before using the two-liquid photosensitive adhesive, first dissolve the photosensitive agent in water according to the formula, then mix it with latex, fully stir and let it stand for 1-2 hours, and then use it after the bubbles disappear completely.

Second, the principle that should be followed when using photosensitive adhesive: appropriate is the best.

Third, the current common photosensitive adhesive brands

(I) Tian Ling photosensitive adhesive of Japanese Mitsubishi Liyang Co., Ltd.: Tian Ling photosensitive adhesive oily S-600B Scope of application: it is suitable for all solvent-based inks such as signs, PCB electronics industry, clothing printing, glass and ceramics. Appearance: blue viscous resin solution solid content: 26% (weight percentage) viscosity: 15000MPA. S

(II) Domestic brand Shanghai Jinyu Photosensitive Adhesive: Scope of application: it is suitable for sticking cloth on a non-displaced countertop, and can also be used for sticking labels and other papers. Product advantages: high viscosity, reusable. Usage: The glue on the upper platen must be evenly daubed with a spatula, and then pasted after the glue is completely dried (the new platen must be scraped 8- 12 times, and the new platen must be cleaned and fully dried before the glue on the platen can be coated). The flannel on the surface of the platen can be printed with clear water. To thoroughly clean the bed board glue, you can clean it and soak it in warm water for 5- 10 minutes before cleaning. Special adhesive for bedplate, with strong viscosity, is difficult to stick.

(3) Domestic brand Beijing Taiping Bridge photosensitive adhesive: Scope of application: (DM-II diazo photosensitive adhesive is suitable for all water-based inks and water-based color pastes. The main applications include: fabric printing, water-based ceramics, etc. Good water resistance, high resolution, minimum line width up to 50μ, long exposure time and good printing resistance. The storage period of photosensitive adhesive before exposure (room temperature is about 25℃, protected from light) is 1 year, and after exposure (about 5℃, in refrigerator) is 1-3 months. )。 Product features: DM-ⅱ diazo photosensitive adhesive is suitable for all water-based inks and water-based color pastes. Description: Good water resistance, high resolution, minimum line width up to 50μ, long exposure time and good printability.

& amp#8205; (4&# 8205) Swiss brand cote171photosensitive adhesive: cote171photosensitive adhesive is a diazo photosensitive material with high resolution and easy peeling, which allows you to.

(V) Japanese brand Murakami photosensitive adhesive: Murakami photosensitive adhesive AD20 (diazo solvent-resistant type): Product features: high resolution, viaduct performance and good solvent resistance. The screen has good flexibility and printability. The coating is easy to handle. Screen stripping has excellent reproducibility.

(VI) British brand Ketutai 7000 photosensitive adhesive: Ketutai 7000 series photosensitive adhesive: easy to develop, strong printing resistance, easy to release and easy to regenerate. Self-printing Cotutai photosensitive adhesive has high resolution, no pollution of diazonium salt photosensitive adhesive, and excellent plate-making performance. All kinds of photosensitive adhesives have their own good characteristics and properties.
