Photosensitive adhesive and photosensitive film for screen printing (7)

3. Straight between the photosensitive materials.

Example: (Cut67 film)

Wire mesh processing:

Drug XB-875 1 copy

3 parts of isopropanol

The above-mentioned drugs were applied to the screen and left for 2 to 3 minutes before being washed with water.

Adhesion of the film: Put the film of the film on the table top, and then insert a glass rod with a diameter of 5 to 100 mm under the film. Then, the adhesive liquid is sufficiently coated on both sides of the screen with a squeegee, and the screen is then gently placed on the film side of the film, and the surface tension is applied together. Finally, the screen was reversed for 1 to 2 minutes and dried at a temperature of 40°C. The formulation ratio of the binding solution is as follows:

Drug XD-010 1 copy

Water 7

Photosensitive processing:

Drug XD-011-A 1 copy

Drug XD-011-B 1 copy

Water 2 copies

The photosensitizer synthesized according to the above ratio is coated on the inner surface of the screen with a squeegee and dried, and the sheet is peeled from the corner after drying.

Shaiban: the positive film and the photosensitive film surface close contact and exposure, exposure conditions: 100V, 30A, 60 cm, with arc lamp exposure for 6 minutes.

Development: After exposure, develop from the inside of the screen with warm water of about 30°C. The development from the inside is due to the film on the outside. After the development, moisture was carefully sucked off and dried at a temperature of 40°C.

Finished: After drying, dissolve the solvent 4886 on the surface of the film and wipe dry with a cloth.
