First, the appearance and characteristics:
Project A B
Viscosity: (40 ° C cps) 1100-1150 25
Appearance: colorless transparent
Or you can specify a colorless, transparent
Or yellowish
Second, the ratio: weight ratio A: B = 2:1
Second, use:
1 Preheat: pouring device at 70-80 ° C bake for 1-2 hours to remove moisture.
2, mixed: Weigh a certain amount A material, then, to join the B material, stir.
Degassing: Mixture vacuum for 15-20 minutes in a -0.095 to-0.1Mpa, and then packaged. If the bubble is more difficult to Tuojin, set the A material pre-drying at 60 ℃.
