How to store the adhesive

Each adhesive has a certain storage period. After this period, the viscosity of the adhesive will be affected and the desired effect cannot be achieved. Therefore, the storage method of the adhesive is very important and affects the There are many factors. If you don’t pay attention, it is easy to reduce the storage period. Now let’s take a look at the specific storage methods of common adhesives!

1. The epoxy resin adhesive should be stored in a ventilated, dry, cool, room temperature environment for a period of six months to one year.

2. The phenolic resin adhesive should be packed in a closed container, stored in a cool place away from fire, for a period of six months to one year.

3. The polyisocyanate glue should be put into a brown bottle and stored at low temperature in the dark. Metal containers, rubber and cork stoppers should not be used. And strictly prevent moisture from entering, otherwise polymerization and deterioration will occur; the prepolymer polyurethane adhesive should not be stored at low temperature to prevent condensation. The storage period of component A is 2 years. Contact with active hydrogen substances for a period of six months to one year

4. The storage temperature of urea-formaldehyde resin adhesive should be as low as possible. If 5% methanol is added to improve the storage stability

5. The container for neoprene adhesive should be well sealed. Store at room temperature, not too high (>30°C) or too low (<5°C), and keep away from fire. The storage period is 3 to 6 months.

6. a-Cyanoacrylate adhesive should be stored in a sealed, low temperature, dry, dark, cool place for 1 year. Glass bottles have a longer shelf life than plastic bottles.

7. The anaerobic adhesive should be stored in a cool and dark place. The storage period is half a year. The material of the packaging container should be polyethylene, and iron containers should not be used, and should not be filled, so as to avoid solid isolation from the air and polymerization deterioration.

8. The SA adhesive should be sealed and stored, and the two components must be isolated and placed in a cool, ventilated, low temperature, and dry place for a period of six months to one year.

9. The polyvinyl acetate emulsion (white glue) should be packaged in glass, ceramic and plastic containers. The storage temperature is 5-30°C. Pay attention to antifreeze. The storage period is 1 year.

10. The hot melt adhesive should be stored in the dark, heat insulation and room temperature.

11. Inorganic adhesives should be sealed and stored to prevent moisture absorption from affecting use.
