Operation process
1. Clean the surface: the surface of the potting object will be clean, remove rust, dust, moisture and oil.
2. Sizing: unscrew the hose cap, and prick open the sealing mouth, the glue will be squeezed to the surface has been cleaned up, so that the natural leveling.
3. Curing: the glue absorbs moisture in the air, the surface begins to solidify, gradually to the deep curing, in 24 hours (room temperature and 60% relative humidity) within the curing depth of 3 ~ 4mm.
4. Summer temperature is high, high humidity, curing will be faster; winter temperature is low, low humidity, curing will be slower.
Notes
Silicone rubber absorbs moisture and cures, unused rubber should be sealed and stored. Sealed storage in a cool dry place, storage period of 9 months.
