Usage and precautions of SD6341 epoxy resin sealing adhesive

Weighing: Accurately weigh components A and B, and mix them thoroughly in a 4:1 (mass) ratio. Before weighing, separate components A and B should be stirred evenly to evenly disperse the settled filler into the gel to avoid affecting the colloidal properties.


Mixing: Use manual or machine mixing to thoroughly and evenly mix the rubber material, so that the rubber material has a uniform color. When using manual glue filling process, it is important to note that the one-time amount of glue should not be too much to avoid difficulty in glue filling due to reduced fluidity in the later stage.


Defoaming: It is recommended to place the evenly mixed rubber material in a vacuum cabinet for defoaming, and use vacuum pumping to remove air entrainment during the mixing process.


Sealing: Pour the adhesive material that has completely removed the bubbles into the device to complete the sealing operation. Before sealing, the surface of the device and the container used for mixing should be kept clean and dry.


Curing: Cure the encapsulated device at room temperature. The viscosity of the mixed colloid will gradually increase with time, and attention should be paid to controlling the sealing within an operable time.


This product is not a hazardous material, but do not enter or eye contact.

Store in a cool and dry place, avoiding rain and sunlight. The shelf life is nine months under unopened conditions at 26 ℃.

This product cannot be mixed with other types of colloids!
