Operation and Safety
  • 1. Clean the sealing surface and remove oil stains
  • 2. To ensure uniform distribution of fillers, first mix components A and B evenly
  • 3. Mix components A and B evenly in the mixing tank according to the ratio. It is best to vacuum and defoam for about 5 minutes, and complete the sealing within the operating time. 4. The sealed parts should be cured at room temperature, and after initial solidification, they can enter the next process. It usually takes about 3 hours to cure at room temperature. 5. It is recommended to use specialized sealing equipment for gluing.
Color and packaging

Conventional colors include white and black, and special colors can also be produced according to customer requirements, using 11kg/group or 12kg/group packaging.

Storage and expiration date

This product belongs to non hazardous materials.

Recommended storage temperature: Store in a well ventilated and dry place, with a storage environment temperature below 30C.
