PREFLEX PU is a high modulus single-component polyurethane hybrid sealant which exhibits excellent adhesive properties and remains permanently elastic once cured. The cured sealant has good resistance to water and a wide range of industrial chemicals.
PREFLEX PU is used to seal movement and expansion joints in concrete and masonry structures. It is particularly suitable for sealing in application subject to high levels of vibration, and where a degree of vibration resistance is required. It is suitable for use in marine environments with excellent resistance to saltwater, it is also suitable for structural bonding of construction elements.
