Use instructions


  • 1.   Mix the two components according to the weight ratio of A:B=1:1 and stir well, then remove air bubbles (vacuum or static) and then fill it up.  Note: must stir evenly, otherwise affect the properties of solidified compounds; should be used within the applicable period of the sealant.

  • 2.   About mixing; After mixing component A and component B, manual or mechanical mixing can be adopted. When mixing, high temperature should be avoided because of high speed and long time agitation, so as to avoid shortening operation time and speeding up solidification, in case operate time is not enough. The surface of the product must be cleaned before it is sealed.

  • 3.   The work site and working environment must maintain the air circulation, in case the concentration is too high after the chemical liquid volatilize in the air, causes the staff to be sick (respiratory tract and skin irritation etc.).

  • 4.   The surface in contact with the compound must be cleaned. It is forbidden to mix the compound with organic compounds containing nitrogen, phosphorus, sulfur and heavy metal ions containing Sn,Ph,Hg, Bi, As , in case affect the curing of the compound.

Packaging and preservation


20kg/ set (component A 10kg and B 10kg), transported as non-dangerous goods, stored in a cool (room temperature) dry place, guarantee period is 6 months.
