- Action:
- The construction site should have a good ventilation system.
- The ZJ-PUR800 series belongs to the moisture reactive polyurethane type hot melt adhesive. Please use professional equipment for reactive hot melt adhesives. If ordinary hot melt adhesive equipment is used, it may cause moisture to seep into the product due to poor airtightness, resulting in solidification of the product, which will damage the adhesive machine.
- The recommended construction temperature is between 100~150 ℃, and temperatures exceeding 150 ℃ should be as brief as possible.
- Cleaning:
- For uncured products, construction equipment can be cleaned with a special cleaning agent JS-PUR-CLEAN, which must be thoroughly rinsed.
- The fully cured adhesive is difficult to remove and may require long-term immersion in NMP solvent to remove.
- matters needing attention:
- --PUR products contain a small amount of isocyanate monomers, please be careful when operating. It is not recommended for employees who are allergic to isocyanates.
- --As the product must be used under high temperature, please wear appropriate clothing, gloves, protective glasses and other personal protective equipment, and use appropriate ventilation equipment to remove the possible small amount of smoke
- --Ready to use and do not expose to air for extended periods of time
- --Maintain first in, first out use of materials.
- --Cleaning agents should only be used once and should not be mixed with the product
- --Do not eat in the workplace
