| DOWSIL™ 1-2577 Conformal Coating – Transparent & Flexible PCB Protective Resin |
| Product Description |
| DOWSIL™ 1-2577 is a high-performance, single-component, solvent-free silicone coating designed to protect printed circuit boards (PCBs) from environmental stress. It cures at room temperature to form a clear, flexible barrier against moisture, dust, and vibration. |
| Key Features |
| • Clarity: Transparent (Allows visual inspection of components) • Certification: UL 94 V-0 flame retardancy compliant • Application: Low viscosity for easy spray, dip, or brush application • Curing: Fast room-temperature vulcanizing (RTV) • Protection: High dielectric strength and moisture resistance |
| Applications |
| • Automotive electronics and control units • LED modules, drivers, and power supplies • Telecommunication systems and aerospace electronics • Industrial control boards in harsh environments |
| Advantages |
| • Solvent-free formulation for improved safety and lower environmental impact • Remains flexible after cure to withstand thermal cycling without cracking • Provides a reliable barrier against salt spray and chemical gases • Excellent adhesion to a wide variety of electronic substrates |
