Epoxy resin 608A/B
A, Purpose and Explanation
Epoxy resin 608 ab series such as special soft rubber of two part epoxy resin, moderate viscosity, natural defoaming, high transparency, good room temperature or heating curing softness, good surface, it is mainly used for LED lamp belt of lamp potting, stickers, planar crystal drops of glue, decoration crystal glue, signs, nameplate, the surface encapsulation of the badge or transparent perfusion of electronic components.
B,The properties before hardening
The main agent608A Curing agent608B
Color: Colorless transparent Colorless transparent
Specific gravity: 1.15 1.15
Viscosity25℃: 700-1500CPS 100MAXCPS

C,Conditions of usage
1)Mixing ratio: A: B = 100:50(weight ratio)
2)Hardening conditions: 25 ℃×10 H to 12 H or 55 ℃×2 H (2 g)
3)Usable time: 25℃×40min (100g)

D,The matters needing attention in using
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.

E,The properties after hardening
