ECA Backing Rods are made from closed-cell polyethylene, offering non-absorbent, ultraviolet resistant, and weather-resistant properties. They are reliable for sealing joints and gaps in construction and insulation applications, providing long-lasting and effective protection.
ECA Backing Rods find application in various areas, notably in joints of pre-cast and cast-in-situ concrete elements. Their primary roles include providing support to the joint sealant application, ensuring proper joint sealant geometry (application depth and shape), and preventing the joint sealant from adhering to the top of the expansion joint filler board (3-way bonding). They act as a bond breaker, facilitating efficient and effective sealing of joints while maintaining their integrity and preventing unwanted adhesion.
