Matters needing attention:

1. Preservation of photosensitive gel: Photosensitive gel is best stored at a low temperature of 20 °C and protected from light. Do not store in an environment above 25°C or below 5°C, otherwise, chemical and physical changes are likely to occur, affecting normal use. Please store diazonium in the refrigerator at 0-5 ℃.
2. Screen plate degreasing: before coating photosensitive adhesive should be thoroughly cleaned with the special degreasing agent to remove grease and dirt. After full cleaning and drying, high-quality screen and high printing resistance can be obtained.
3. Dissolution of photosensitizer: Pure water or pure water should be used to dissolve photosensitizer. If tap water is used directly, the minerals and rust in tap water will react chemically with the photosensitive adhesive, affecting the performance. In severe cases, the colloid will agglomerate and cannot be used normally.
4. Drying oven temperature: the temperature of the drying oven is best below 40 ℃, 40 ℃, the photosensitive glue easily generates a thermal response, lowering the solution like sex. The desiccant box should have an exhaust device so that the humidity in the box can be discharged and the net plate can be completely dry.Check whether the temperature inside the

the oven is consistent with the set temperature every month.Check whether the temperature inside the oven is consistent with the set temperature every month.

5. Development in winter: if the water temperature of the product in winter is too low, it will cause poor development of the screen version and a decrease in image resolution. Warm water is recommended.

Features:

1. Easy to paint, short drying time, high screen production efficiency
2. Excellent durability, and superior solvent resistance.
3. Easy to reclaim, extended re-use of the screen.
4. The waterborne diazo photosensitive adhesive is easy to use and has high bonding strength.

Instructions:

1. Wash, degrease, and dry screen mesh. Remove grease and foreign contaminants with MSP cleanser.
2. Dissolve provided diazo with 10% water of emulsion volume. Do not use warm water.
3. Coat the emulsion slowly in order to prevent air bubbles.
4. Dry-coated screen completely before exposure. Drying temperature up to 40°C(104°F).
5. Pour the diazo solution into an emulsion. Mix it well. Prior to use, let mixed emulsions settle for one day.

Or for immediate use, filter it with screen mesh 100/cm or higher.

Widely used in printing, silk screen printing, electronics, lighting, and other industries.

Method of use:

1. Sensitization: dissolve the heavy nitrogen with about 70-100g of pure water. Then pour the diazo

the solution into the photosensitive adhesive and stir with a glass rod or wood rod until the bubbles

disappear.

2. Coating: apply with the high-quality scraper. The characteristics of the coating are related to the

size and tension of the screen. Confirm The Times of coating according to the need for printing,

so as to obtain the required film thickness.If more than 2 projects are needed, the next project

must be carried out after the previous project coating screen plate is completely dry, otherwise,

the film will fall off.

3, drying, drying temperature control for best under 40 ℃, and high temperature can make

thermal sensitive glue affects the plate making, the screen should be fully dry.

4. Exposure: the best light wave is 300nm to 400nm. If using an ultra-high-pressure mercury lamp

or high-voltage gallium iodide lamp, the effect is better.

5. Development: it is recommended to use a high-pressure water gun or spray gun to flush the

the layout at a constant speed.

6, dry: after enhancement, first remove the screen surface water, and then into the oven for

drying under 40 ℃, the need to fully dry, otherwise the screen glue falls easily.

7. Secondary exposure: the exposure time of the S surface is 1-2 times that of the P surface, which can

greatly improve the printing resistance.

8, hardening: after being screened completely dry, after the blending of A + B hardening liquid

evenly coated in the version of the P and S face, 1 to 2 minutes after using an air gun to blow through

the ink area, dry for 20 to 30 minutes, can significantly improve the network version of resistance rate.
