Product Description

The SHARPIE MSC1-11 Modified Transparent Silicone Sealant is a one-component,
moisture-cure, high-clarity sealant that delivers a clean, natural finish with minimal staining.
It cures into a flexible, durable seal that blends with substrate colors, making it ideal for
applications where a “seal does not exist” appearance is desired.
Recommended for switchboards, louvers, mailboxes, wood, stone, and metal surfaces,
it provides waterproofing and long-term adhesion.
