Seamsil® 400 Bolt Encapsulation System
Problems with corrosion on metal roof fixings
Over time, bolts used to fix metal roof sheets can be at risk of corrosion, moisture and other damage from environmental factors. This can weaken the bolts, meaning they are likely to become loose and break. Using a bolt encapsulation system can be an effective way to protect bolts from damage and extend their lifespan.
Bolt encapsulation systems are the most sustainable option for protecting bolts and improving the environmental impact of structures and equipment. By decreasing the demand for new materials and reducing maintenance requirements, these systems can help promote sustainability and reduce waste.
Seamsil® 400 is a silicone based system engineered specifically to prevent further corrosion of roof sheet bolts and fixings by providing a temporary, protective elastic seal.

- Use as a standalone system or with the Delcote® full roof coating system.
- Backed by a 10 or 25 year guarantee when applied as part of the Delcote® full roof coating system.
