Blend Ratio

Main Body : OG461 = 100 wt%

Curing Agent OG830 for OG461 = 1.0 wt%

Pick Main Body up from the refrigerator

And Keep it in the room and store until main body up to room temperature (>6 Hours) as unopened (Avoid Dew condensation)

Curing Agent solution should NOT be in the refrigerator.

Thinner

In case it need to adjust viscosity

Storage Condition

Main Body : OG461 = Refrigerated storage below 5°C
Shelf life : 3 Months after manufacturing

Curing Agent : OG830, OG831, OG840 = Room Temperature
Shelf life : 6 Months after manufacturing
Recommended Curing Conditions: Drying Condition

90°C for 10 min in the Box Oven or Equivalent Heat amount of Belt dryer

Good air Ventilation is needed
