The sealant cures with the moisture in the air. The lower the temperature is, and the lower the humidity is, the slower the curing rate is.
The suggested work temperature is 5-35° C, the best work temperature is 15-25° C.

5. Property of the Sealant Layer
The product cures with the moisture in the air, which forms a high strength elastic structural sealant layer.
The sealant layer is resistant to water, weak acid, neutral cleaner which do not contain chlor-alkali. It can shortly resistant to fuel, oil, fat, and crude oil. But it should be avoided strong acid, lye, bleach and other organic solvent.
