It should not be used in pure oxygen and/or enriched oxygen, and cannot be used as a sealing material for chlorine gas or other strong oxidizing substances.
Guidelines for using the dispensing process:
1. Products stored in cold storage must be restored to room temperature before use (usually takes about 2-4 hours).
2. Before use, thoroughly clean the dispensing nozzle, adapter, and other accessories to avoid cross contamination with other epoxy or acrylic adhesives.
3. When the dispensing machine is not working, do not place the used and uncleaned glue needle nozzle or adapter on the dispensing machine for more than 24 hours.
4. Do not soak the uncleaned dispensing needle tip in solvent for a long time.
5.The amount of glue dispensed depends on the working pressure, time, size of the dispensing nozzle, and environmental temperature.
6. These parameters vary depending on the model of the dispensing machine and require process optimization.
The ideal dispensing temperature should be controlled between 30-38 ℃, and it is not recommended to dispense at higher temperatures.
SMT patch adhesive scraping printing usage guide:
1. The product should be refrigerated and stored in the refrigerator, and it needs to be reheated for 2-4 hours before use.
During printing operations, the environmental requirements are 25 ℃ temperature and relative humidity less than 70%.
The amount of adhesive used depends on factors such as the material being adhered, printing speed, height of the adhesive mold, contact pressure and temperature of the scraper.
Storage conditions:
The ideal storage condition is to refrigerate unopened products in a dry place at 2-10 ℃.
2. Refrigerated products must be restored to room temperature before use.
3. To avoid contamination of the original adhesive, any used adhesive must not be returned to the original packaging.
