| DOWSIL™ 1-2577 Conformal Coating – Clear and Flexible PCB Protective Coating |
| Product Description |
| DOWSIL™ 1-2577 is a transparent, single-component, solvent-free silicone coating material developed to protect electronic circuit boards (PCBs) against harsh environmental conditions. This product cures at room temperature (RTV) and provides an excellent barrier against moisture and vibration. |
| Key Features |
| • Appearance: Clear (allows component inspection) • Certification: UL 94 V-0 flame retardant compliance • Application: Low viscosity suitable for brush, dip, or spray methods • Curing: Fast curing at room temperature (RTV) • Durability: Resistance to moisture, dust, chemical vapors, and thermal shock |
| Applications |
| • Automotive control units and telecommunication systems • LED modules, drivers, and power supplies • Military and aerospace electronics • Industrial control panels and outdoor devices |
| Benefits |
| • Solvent-free structure makes it environmentally friendly and safe to use • After curing, its flexible structure prevents cracking during thermal expansion • Excellent electrical insulation with high dielectric strength • Provides long-term stability in challenging outdoor and marine-type applications |
