ACTFLEX 75 FC
moisture-curing polyurethane
Rapid moisture-curing, high-modulus polyurethane joint sealant and adhesive designed for sealing, bonding, and waterproofing in construction and industrial applications.
ACTFLEX 75FC is a high-performance, moisture-curing polyurethane joint sealant and adhesive formulated for construction and waterproofing systems. Once cured, it forms a flexible, durable, and weather-resistant bond capable of accommodating differential movement between dissimilar materials.
Designed for use on concrete, FC sheeting, timber, metals, and PVC (with primer), it is suitable for sealing joints, penetrations, cracks, and waterproofing overlaps. It offers superior adhesion, shock resistance, and vibration damping with high recovery characteristics, making it suitable for moving joints and exposed environments.
