Epoxy 607A / B
First, use instructions
607AB epoxy group-based epoxy resin double soft, good leveling, natural defoaming, high transparency, good toughness, room temperature or heat curing flexibility, good surface, mainly for LED potting, signs, Ming transparent plate, badge or surface-mount electronic components perfusion.
Second, the nature ago harden
Main agent 607A curing agent 607B
Color: colorless, transparent colorless, transparent
Weight: 1.15 1.15
Viscosity 25 ℃: 150-400CPS100MAXCPS
Third, the use conditions
1) mixing ratio: A: B = 100: 33 (weight ratio)
2) Curing conditions: 25 ℃ * 10H-13H or 55 ℃ * 2H (2g)
3) Use Time: 25 ℃ * 45min
Fourth, note the use of:
1. Working environment: Sheng plastic containers Keep clean, A, B groups were strictly weight ratio, accurately weighed, in a clockwise stir evenly along the vessel wall to stand 3-5 minutes before use.
The operating time and the amount of the deployment of the glue, to avoid wastage. When the temperature is below 15 ℃, please be A plastic preheated to 30 ℃ and then be adjusted glue, easy to operate (low temperature glue will thicken when A ); required sealing lid after use to avoid moisture absorption and cause product obsolescence.
3. When the relative humidity is greater than 85%, the cured surface easily absorb moisture in the air, forming a layer of white mist, so when the relative humidity is greater than 85%, not suitable for room temperature curing, heat curing is recommended.
Fifth, after the hardening properties
1) withstand voltage KV / mm 38
2) Yuden rate 1KHZ 3.7
3) Water absorption% 24 hours (0.1
4) Bending strength Kg / mm2 28
5) Volume resistivity Ohm3 1x10 15
6) dielectric loss 1KHZ 0.42
7) Compressive strength Kg / mm2 8.4
8) Impact strength Kg / cm / cm2 6.8
9) surface resistance Ohmm2 5X10 15
Performance data is at a temperature above 25 ℃, humidity of 70% typical data measured in the laboratory environment, only for reference.
