Product Introduction
Cemedine SX-720 (available in Black/720B and White/720W) is a single-component, moisture-curing elastic adhesive designed for electronic and industrial applications. It features solvent-free formulation, compliance with RoHS/REACH, and UL94 V-0 certification, making it ideal for safety-critical environments. Its rapid initial cure (5–10 minutes) and flexibility (Shore A 40) ensure efficient production and vibration resistance.
Enhanced Properties
- Flame Resistance: UL94 V-0 certification (File E124199) with smoke density ≤15, exceeding industrial standards (e.g., older 8008 series: smoke density ≈28)
- Environmental Adaptability: Withstands extreme conditions (-40°C to 120°C), including automotive engine compartments and subzero environments.
- Operational Simplicity: No mixing/heating required; cures via ambient moisture. Open-tube working time extends to 40 minutes (vs. 30 minutes for 8008 series).
Application Scenarios
Based on verified use cases for SX-720B/W:
- Electronics Encapsulation:
- Power Modules: Bonds heat sinks to PCBs, providing 15 kV/mm insulation and flame resistance (UL-certified)
- Sensors: Seals automotive oxygen sensors (IP67 waterproof/salt-spray resistance), extending lifespan by 70% in -40°C–120°C cycles.
- Battery & EV Systems:
- Li-ion Battery Fixation: Elastic buffering reduces fracture risk from cell expansion during charge/discharge
- Industrial Maintenance:
- Chemical Equipment: Repairs reaction vessels (resists 80°C weak alkali wash; cost ≈5% of replacement).
- Geothermal Pipelines: Maintains seals in 110°C acidic steam (pH=4) for 18+ months
