Winsil 20 is a one-part silicone sealant that forms an elastic, rubber-like seal when exposed to atmospheric moisture.

Winsil 20 is designed for ease of application and consistent performance in various joint sealing tasks. Its moisture-cure formula sets at room temperature and does not require mixing or special tools. Once cured, the sealant forms a flexible, weather-tolerant seal that is resistant to common environmental exposures including UV, ozone, and temperature change.

The product is compatible with many common construction surfaces and does not require priming in most applications. During the curing process, it releases methyl alcohol and ammonia vapours.
