Polyurea Expansion Joint Filler
CAS Number: 9009-54-5
Two-component polyurea elastomeric joint filler provides flexible, durable sealing of expansion joints, control joints, and isolation joints in concrete floors and pavements. It delivers excellent resistance to dynamic loading, wheel traffic, thermal expansion, and chemical spills. Polyurea cures in 30–60 minutes at ambient temperature and offers superior abrasion resistance compared to polyurethane- or silicone-based joint sealants.
