A, Purpose and Explanation
Epoxy resin 6992 ab is epoxy resin adhesive cured under the condition of normal temperature and low temperature, high hardness, can be polished, fast curing time, high transparent, can heat curing. Dedicated to paddle board surface cover, the LED potting, carbon fiber products cover, jewelry surface cover, mould filling, and the insulation of other electronic components , moistureproof, potting, confidential encapsulation , etc.
B, The properties before hardening
The main agent6992A Curing agent6992B
Color: Colorless transparent Colorless transparent
Specific gravity: 1.15 0.96
Viscosity25℃: 1200-2500CPS 100MAXCPS

C, Conditions of usage
1)Mixing ratio: A: B = 100:25(weight ratio)
2)Hardening conditions: 25 ℃× 3H or 55℃×15min(2 g)
3)Usable time: 25℃×10min (100g)

D, Application method
1.Working environment: The container of holding glue please keep clean, A and B part should be in accordance with the weight ratio, weigh accurately , mix fully along the container wall by clockwise and use after 3 to 5 minutes .
2.According to the operational time and dosage of mixing rubber, avoid wasting. When the temperature below 15 ℃, please put A glue to glue again after warm up to 30 ℃, easy to operate, (a glue will be thicken when low temperature ); Must be sealed lid after use, avoid product rejection caused by moisture absorption.
3.When the relative humidity is more than 85%, the curing surface easy to absorb moisture in the air, form a layer of white mist, so when the relative humidity is more than 85%, is not suitable for room temperature curing, s est to use the heat curing.
