Operation and Safety
  • usage method:
  • 1. Completely remove impurities such as water, oil, and dirt from the surface of the substrate, and keep the surface clean;
  • When using barreled sealant, it is necessary to use appropriate hot melt adhesive preparation and set the equipment temperature according to the application process to evenly extrude the sealant onto the surface of the adhesive substrate; When using the adhesive strip, lay the adhesive strip on the surface of the substrate to be bonded at once, and then press the adhesive strip in sequence to make it tightly contact with the substrate;
  • 3. It is recommended to apply the adhesive at a temperature of 120 ℃~140 ℃. Suitable pressing temperature can be adjusted according to actual working conditions and application requirements.
  • matters needing attention:
  • It is recommended to use a dedicated glue applicator. After stopping the production line, turn off the gluing machine to avoid the long-term high-temperature state of butyl rubber affecting its performance.
  • ZJ-302PV is a reactive butyl hot melt adhesive that can react slowly with moisture in the air, avoiding long-term exposure to air during use.
  • Health and Safety:
  • This product information manual does not include product safety information for safety instructions.
  • It must be specifically noted that:
  • Avoid contacting sealant products with food and cosmetics;
  • During the gluing process, if the temperature of the glue and equipment is high, take measures to prevent burns.
