4. Methods of use
 ◆ Determine the base material

Remove loose layer where sizing is required. If there is a coating or paint layer, ensure that there is sufficient adhesion. If the adhesion is not enough, relevant tools such as steel balls can be used to clean the parts to be gummed, so that it is clean, hard, dry and free of grease and surface dirt such as release agents, maintenance films and hydrophobic agents.

 ◆ Sizing

According to the size of the bonding surface and the gap, cut the extrusion nozzle and squeeze it out evenly. The coating amount is controlled by the size of the extrusion nozzle hole. It is appropriate to slightly extrude a rubber ring after the combination of the bonding surface. After the binding surface is coated with a gasket, the combination is quickly tightened during the active period, usually the time interval from extrusion to combination should be as short as possible, so as not to dry the vulcanization table and cannot be used.  

After vulcanization, the liquid gasket remaining on the bonding surface can be cut off with a sharp knife and lost to the adhesive film outside the bonding surface, but it is not allowed to tear by hand. It can also be wiped off with cotton gauze soaked with gasoline.

 

5. Storage and expiration date
      It belongs to non-dangerous goods, please store in a cool and dry place with a temperature below 27℃, valid for 9 months, it is recommended to use within 6 months after purchase.

 

Six, precautions

    However, before curing, avoid contact with eyes and children; Keep the working environment area well ventilated.

Seven, packaging specifications: 310ml/ pieces,30 pieces/box; 590ml/ PCS, 20 PCS/box.
