Tonsan® MT3710 is a two-component anaerobic adhesive designed for room temperature curing. Its specialty lies in bonding motor silicon steel sheets. With medium viscosity, it rapidly cures at room temperature when used in conjunction with the MT3300 primer, resulting in high-strength bonds after curing. This adhesive is tailored to meet the specific performance demands of motor operation.

Appplication Instructions
  1. Surface treatment: clean the surface of silicon steel sheet with alcohol or acetone to ensure that the surface is clean. If stamping oil is needed, appropriate amount is recommended, otherwise it will affect the bonding strength after curing.
  2. Coating primer: if manually used, it is recommended to spray the primer evenly on the substrates, and wait 1-2 minutes until the solvent volatilized and then apply glue; if used by machine, it is recommended to set a reasonable spraying amount according to the amount of adhesive.
  3. Sizing: it is recommended to use the machine to glue, and the amount of glue should be tested in advance to ensure that the spread area of glue is moderate, and no glue overflow occurs after pressing;
  4. Assembly: after gluing, the silicon steel sheets can be stacked together in a specific mold, and certain pressure is applied to make the gap between the silicon steel sheets meet the size requirements.
  5. Curing: put the fixed mold at room temperature for curing. Note: in the curing process do not make the product by external force impact to avoid damage and failure.
