Technical Parameters

Directions for Use

Preparation

• Stirring: Fully stir part A and part B separately, either manually or mechanically, to ensure homogeneity and avoid performance changes due to filler settlement.

Mixing

• Weighing: Accurately weigh the two parts into a clean container by weight ratio (1:1) and stir well to ensure thorough mixing.

Defoaming

• Natural Defoaming: Allow 20-30 minutes for natural defoaming after filling the mixed glue into the components.
• Vacuum Defoaming: For faster defoaming, pot the components after pumping for 5-10 minutes at a vacuum degree of 0.08-0.1 MPa.

Potting

• Surface Preparation: Ensure the surfaces to be potted are clean and dry. Apply the glue while it still has good flowability to achieve optimal leveling.

Curing

• Curing Conditions: The glue can cure at room temperature or by heating. Higher temperatures accelerate curing, and heat curing is recommended in colder conditions (e.g., winter).
