  • This product is a two-component product. Packaging specifications: A component: 12KG / barrel, B component: 2KG / barrel.
  • This product should be stored in a cool and dry place below 27 ℃, the storage period is 6 months from the date of production.



  • Preparation: Before mixing, first observe the state of component A. If there is sedimentation and layering, please stir evenly before use. Prepare samples for potting.
  • Mixing: The products are mixed according to the ratio (weight) of A: B = 6: 1, stir well and degas by vacuuming.
  • Encapsulation: Encapsulate the evenly mixed compound into the product to be encapsulated as soon as possible, and cure naturally at room temperature. After initial curing, it can enter the next process (after 30min). Do not transport components before curing.
