Application
Suitable for automobile ignition ring, motorcycle ignition ring, sensor and other electronic component packaging.
Characteristics
It has good insulation performance, high permeability, good fluidity, excellent heat resistance, excellent surface gloss and good processability.
Test datas, as bellow:
One-component performance (before curing)
Property after curing (25ºC, 5-6 hours curing)
Mixing Ratio
100:80-20
Package
Component A: 30kg /barrel
Component B: 5kg /barrel
Storage Conditions
The product should be sealed in its original packaging container and stored in a dry and ventilated place. In an environment of 18-40ºC, the shelf life is 6 months. If the shelf life is exceeded, analysis is required to determine whether it is still valid.
Due to the storage conditions, this product may experience a small amount of precipitation during storage, which is a normal phenomenon. After stirring evenly, it can be used normally.
