Description
AC-POLYSEAL (NS) is a high-performance, two-part cross-linking polysulphide sealant specifically engineered for vertical and overhead expansion joints. Formulated with a liquid polysulphide polymer, it offers enhanced stickiness for superior adhesion and remains permanently elastic to accommodate structural movement.
Primary Applications
- Vertical & Overhead Sealing: Ideal for retaining walls, building facades, underpasses, and tunnels where non-sag properties are critical.
- Heavy Infrastructure: Sealing expansion and construction joints in bridges, rigid pavements (roads), and subways.
- Industrial & Water Works: Securely seals reservoirs, basements, and gaps between pipelines and RCC supports.
- Precast Construction: Perfect for jointing precast concrete elements in high- and low-rise buildings.
Key Advantages
- Non-Sag Consistency: Specially formulated to stay in place within vertical and overhead joints without slumping.
- Permanent Elasticity: Maintains a flexible, watertight seal despite continuous thermal and structural cycles.
- Enhanced Adhesion: Superior “tack” ensures excellent bonding to diverse substrates including concrete, metal, and masonry.
- Environmental Resilience: High resistance to UV radiation, weathering, and industrial chemicals.
- Economic Durability: A cost-effective solution for long-term protection of critical civil engineering gaps.
