working process
Here the techinics can be divides into two kinds: manual process andmachine process, the former one cures longer than the later one.
1manual process
a    Keep 4030A/B in the room with the temperature of 15~25 and the humidity < 70% for 24 hours before use. 4030A may rime in low temperature, please warm up to 30~40 till it turns to clear liquid
bPut label on the worktable and fix with adhesive tape.
cClean the dust and dirt on the label
dWeigh 4030A/B correctly, the weight ratio is 100: 55. Stir them adequately.  
eVacuum the mixture to de-bubble
fInject on the surface of label
gmake the liquid all around the surface with needle, and break the bubble
hPut the label in the clean room of 15-25 and humidity <70% for 24 hours
 2machine process
   Keep 4030A/B in the room with the temperature of 15~25 and the humidity < 70% for 96 hours before use to eliminate bubbles
   Put the pump respectively into 4030A and 4030B, sealed and fixed, leave them still.
  Put label on the worktable and fixed with adhesive tape.
  Clean the dust and dirt on the label
   wash blender, pipe and injecting pinhead with dichloromethane

   inject on the surface of label
  make the liquid all around the surface with needle, and break the bubble
  Put the label in the clean room of 15-25 and humidity <70% for 24 hours
