£32.80
A robust single-component hot-melt butyl sealant specifically designed for the primary edge sealing of insulating glass units (IG units).
About this product
Bostik 4000 sealant is applied in a molten state and cools quickly, allowing for rapid handling and processing of IG units in fast-paced production environments. As part of Bostik's high-performance IG sealant range, Bostik 4000 offers excellent resistance to moisture vapour and maximises the retention of inert gases, ensuring the long-term durability and thermal efficiency of sealed units.
Features
- Superior Moisture and Gas Barrier: Bostik 4000 has a very low moisture vapour transmission rate (MVTR), effectively protecting the IG unit's cavity from moisture ingress. This maximises the unit's service life and prevents fogging.
- Rapid Curing for High-Speed Production: As a hot melt sealant, it sets almost instantly upon cooling, which eliminates lengthy curing times and significantly increases production line speed and overall manufacturing efficiency.
- Excellent Processability: The formula is optimised for clean and consistent application, ensuring a uniform seal with both manual and automated dispensing equipment.
- Strong Adhesion: It creates a durable, long-lasting bond with standard spacer bar materials, including aluminium, galvanised steel, stainless steel, and glass.
- Proven Performance: Bostik 4000 meets or exceeds leading industry standards for insulating glass sealants, providing fabricators with a reliable and trusted solution.
- Efficient Packaging: The 6.5 kg block is conveniently sized for production environments.
Suitable For
