Product description of epoxy compound

SATOP®8662 is a one component, high-performance epoxy resin structural adhesive, epoxy compound developed for power electronics and electronic devices that are becoming smaller, lighter, and higher in output.

Suitable for structure bonding and reinforcing adhesion of small industrial products. assembly and bonding of ferrite and magnetic steel in the production of magneto motors, and adhesion and fixation of the motor rotor neck and motor winding coil joints, compared with the currently widely used anaerobic adhesives and two-component acrylic adhesives, Good electrical, chemical, thermal and physical properties. Its good operating performance can be further automated and high – speed assembly technology. Widely used in various electronic devices, including semiconductors, relays, motors, inductors, coils, pickup and so on.

  • Good storage stability at room temperature
  • Quick curing under heating conditions
  • After curing, it has strong toughness, high bonding strength, impact resistance, shock resistance
  • Good resistance to acid and alkali, moisture-proof and waterproof, oil-proof and dust-proof performance, heat resistance and atmospheric aging
  • Good insulation and pressure resistance

Remark: 1. The data in the table is actual measured data under certain conditions and is for reference only. It does not guarantee that the data obtained by the customer in actual use can be completely consistent with it.

              2.Curing process: Curing at 120°C for 1 hour.

Using process of epoxy compound

  • If epoxy adhesive is stored in a frozen environment, it must be removed and used for thawing at room temperature before use. During sizing process, the epoxy adhesive should be avoided from being placed in a high-temperature environment to reduce the consistency of the glue, unless it has been tested and confirmed in advance.
  • Apply this adhesive directly to the surface of the bonded object, which is treated with oil removal, rust removal and roughening treatment, and select the appropriate tool to assist the gluing and fixing with the fixture. Then choose one of the following three ways.

Remark: above curing time refers to the time after the glue temperature reaches the corresponding temperature.

  1. Method 1, long-term temperature 120℃,
  2. Method 2, long-term temperature150℃,
  3. Method 3, long-term temperature200℃.

Therefore, for objects with large volume and slow heat transfer, due to heat transfer rate, curing time should be extended accordingly. Please refer to actual measured data.

During the curing process, if the amount of glue applied is too high or the temperature is too high, air bubbles may be generated. In such cases, please reduce curing temperature appropriately.

Precautions of epoxy compound

  • Because the product is heated reacts to chemical products, so the effect of environmental temperature on the product quality is very big, please send the product stored in low temperature environment, in order to ensure the stability of the product and quality. After taking out the unused colloid, please cover it tightly and put it back into the frozen environment.
  • Few people contact adhesive solution for a long time will produce mild skin irritation, itch had mild pain, it is recommended to use when wear protective gloves, please with skin with acetone or alcohol wipe, and use cleaner clean.
  • Before using it in large quantities, please try it out in small quantities and master the skills of using the product so as to avoid mistakes.
