Application Note
1. Clean surface to make it clean, dry, free of oil or grease.
2. The sealant cures with the moisture in the air. The lower the temperature and humidity is, the
slower the curing is; and the higher the temperature and humidity is, the faster the curing is.
3. The best work temperature is 10-35°C.
