Two-Component Polysulphide Sealant for Expansion Joints Construction Featuring Silicone Main Raw Material High Performance Glue

Technical specifications

Customization guide

Adjustable parameters:

• Mixing ratio (A:B): Optimize from 10:1 to 15:1 to balance cure speed and viscosity for substrates like concrete vs. metal.
• Curing time: Modify via temperature control (15–30°C) to align with project timelines.

Supplier's note

1. Technical Breakthroughs:

   • High Viscosity Control: Enables vertical application without drooping, unlike low-viscosity competitors.
   • 15.6 MPa Tensile Strength (Pro): Outperforms industry benchmarks by 30%, ideal for seismic zones.
   • Triple-Standard Chemical Resistance: Safeguards against aggressive chemicals in marine or industrial settings.

2. Optimal Version Selection:

   • Base Model: Suitable for standard residential projects requiring basic weather resistance.
   • Advanced Model: Preferred for commercial buildings with frequent exposure to chemicals (e.g., hospitals, labs).
   • Pro Model: Mandatory for extreme environments (e.g., coastal bridges, high-rise glass facades) where durability and speed are critical. With its 50% faster cure time, it reduces downtime by 12 hours compared to traditional sealants.
