Precautions for Automotive Inductive Adhesive

  1. The place of use must have good ventilation. 2 Component A is a homogeneous and stable solution of volatile solvents, with flammable and explosive properties. During storage, it should be kept away from open flames and direct sunlight, and containers containing component A should not be heated.
    During transportation and use, handle with care and pay attention to ventilation and air permeability. The storage temperature should be below 30 ℃ and sealed for storage.
  2. Component B is a grayish white sheet-like solid that can be oxidized to a grayish black or even brownish black solid upon contact with air. The change in color does not affect its curing properties as a curing agent. The B component has certain hazards, and the operation requires wearing protective gloves and masks. It is strictly prohibited to directly touch the B agent with hands.
  3. When using the main agent and curing agent, specialized equipment should be used to mix them evenly according to the specified ratio.
  4. After adjusting the main agent and curing agent, they should be used up within the operable time.
    When the material comes into contact with the skin, wipe it off with a cloth and rinse the affected area with water and soap.
