FAQS

What materials is the 9900 Silicone Sealant suitable for?

This is a structural sealant with superior adhesion, specifically designed for glass, aluminum frames (ACP), granite, ceramics, and concrete. It is particularly suitable for installing glass curtain walls and sealing construction gaps.

Why should I choose the sausage pack instead of the standard cartridge?Accordion item 2

Sausage packs (foil packs) typically offer a larger capacity (approx. 500-600ml compared to 300ml for cartridges), offering significant cost savings for large projects. Additionally, the soft foil packaging allows for easy extrusion of all the sealant, minimizing material waste and reducing plastic waste.


Can this sealant withstand harsh outdoor weather conditions?

Yes. The 9900 sealant features excellent UV resistance and weatherability. It does not become brittle, crack, or discolor under direct sunlight, ensuring long-lasting waterproofing for roofs and walls.


Does it have a strong odor or cause metal corrosion?

No. This is a Neutral Cure sealant, so it does not have a strong acidic smell (like acetic silicones) and is completely non-corrosive to metals, helping to preserve aluminum frames and roofing sheets over time.


How long does it take for the sealant to cure completely?

Typically, the sealant will form a surface skin within 10-15 minutes. However, to fully cure and achieve maximum adhesion, it requires approximately 24 hours (actual curing time may vary depending on the sealant thickness and ambient humidity).
