How to Use
Here are some general guidelines on how to use DOWSIL™ 798 Cold and Cleanroom Silicone Sealant:
- Surface Preparation: Surfaces should be clean, dry, and free of dust, grease, and other contaminants. If necessary, clean surfaces with a suitable solvent, such as isopropyl alcohol.
- Application: Cut the nozzle to the desired size and apply the sealant in a continuous bead, ensuring that the sealant is in contact with both surfaces to be sealed. Tool the sealant immediately after application to ensure that it fills all gaps and voids.
- Curing: DOWSIL™ 798 Cold and Cleanroom Silicone Sealant is a one-part, moisture-curing sealant. It cures at room temperature and requires moisture in the air to cure. The cure time will depend on the ambient temperature, humidity, and depth of the sealant. In general, the sealant will form a skin in 10-20 minutes and will cure to a depth of 3mm in 24 hours.
- Clean-up: DOWSIL™ 798 Cold and Cleanroom Silicone Sealant can be cleaned up with a suitable solvent, such as isopropyl alcohol, before it cures. After it has cured, the sealant can be removed mechanically.
- Storage: Store DOWSIL™ 798 Cold and Cleanroom Silicone Sealant in a cool, dry place, away from direct sunlight and heat sources. Do not store the sealant at temperatures above 32°C.
