Use restrictions
  1. For structural bonding.
  2. When substrate surface temperature beyond 50º C or below 5º C.
  3. To ensure the sealing and caulking effect, twice execution is necessary when the width beyond 20mm or depth beyond 10mm, meanwhile not to remain any cavity.
  4. Color turning yellow or deep after execution is a normal phenomenon which will not affect the properties.
  5. Width should be considered according to the 20% volume shrinkage caused by solution evaporation.
