Operating Instructions:

  1. Clean Surface: Ensure the surface of the bonding substrate is free from dust, rust, and oil.
  2. Gluing: Squeeze the sealant onto the cleaned surface.
  3. Curing: Place the glued part in the air. After skin formation, curing continues inward from the surface. Under 25°C and 55% relative humidity conditions, it cures to a depth of 2 to 4mm in 24 hours. The curing depth gradually increases over time.
  4. Storage: The unused sealant should be tightly sealed. Before reusing, remove any crust at the nozzle without affecting normal use. During storage, a small amount of solidification at the nozzle may occur, but it can be used normally after removal without affecting product properties.

Storage Conditions:

  • Store in a cool and dry place below 35°C.
  • Shelf Life: 6 months

Attention:

  1. Keep away from children.
  2. It is recommended to use the sealant in a well-ventilated area to reduce odor.
  3. If it accidentally comes into contact with the skin or eyes, wipe them clean immediately, rinse with water, and seek medical advice.
  4. For safety information, please refer to the Material Safety Data Sheet (MSDS).
