Precautions for Use

  1. Only deionized water shall be adopted for emulsion dilution; tap water may lead to flocculation, demulsification and other defects.
  2. Compatibility and storage stability tests shall be carried out before mixing this product with other raw materials.
  3. Mixtures blended with isocyanate curing agent must be fully consumed within 4 hours. Any unused mixture shall not be poured back into the original adhesive container.
 

Storage

The shelf life of this product is six months counting from the production date. A full performance evaluation is required prior to use once the shelf life expires.
 
Recommended storage temperature range: 5–35°C. Storage below 5°C will cause viscosity increase or irreversible damage to the product. Long-term storage under high temperature may degrade product performance and trigger sedimentation or coagulation.
 
Store away from light and keep packaging intact; otherwise, water evaporation will form a surface film on the product.
 
Skinning and caking are unavoidable during storage and transportation due to the film-forming property of the product, so filtration must be performed before use.
