Adheseal Closed Cell Backing Rod is manufactured from closed cell, low-density white polyethylene foam, offering exceptional resistance to weathering and chemicals. Its flexible, round profile ensures sealants form the correct shape for optimal movement and performance. Ideal for various construction applications, this backing rod provides a reliable bond breaker and joint filler, enhancing the longevity of sealants.
Adheseal Closed Cell Backing Rod is made from closed cell, low-density polyethylene foam, providing excellent compression and recovery properties. Its round profile ensures sealants form the correct shape, and its resistance to weathering and chemicals makes it ideal for various construction applications.
Physical Properties: Closed cell structure, 95% recovery, wide temperature range (-60°C to 260°C intermittent), and excellent chemical resistance.
Application: Fill prepared joints, avoid air entrapment, use an insertion tool, and protect the outer surface during installation.
Q: What is the benefit of using a closed cell backing rod?
A: Closed cell backing rods minimize water absorption, making them ideal for damp environments and ensuring long-term durability and sealant performance.
Q: Can I use this backing rod with any type of sealant?
A: Yes, it is compatible with cold applied sealants, including Acrylic, Silicone, PU, MS, SPUR, and Hybrid types. However, consult our technical department for hot poured sealants.
Q: How do I choose the correct size backing rod?
A: The backing rod should be 25% larger than the joint width to ensure it stays in place during sealant installation and allows for proper sealant thickness (half the joint width).
Q: What precautions should I take during installation?
A: Avoid excessive stretching, use an insertion tool to ensure proper depth, and take care not to damage the rod's outer surface to maintain sealant integrity.
Q: Is this product suitable for swimming pool applications?
A: It is not suitable for internal swimming pool applications with high chlorine levels (above 5ppm). High chlorine can degrade the backing rod.
Q: Can this backing rod be used in outdoor applications?
A: Yes, it is suitable for both internal and external applications. However, it should not be directly exposed to UV light.
