Technical Product Information |  |
| DOWSIL™ 1-2577 Conformal Coating Clear 199.5 KG (Drum) |
| Product Overview |
| DOWSIL™ 1-2577 Conformal Coating Clear is a 1-part, solvent-borne, RTV elastomeric silicone conformal coating designed for protecting printed circuit boards (PCBs) and sensitive electronic components against moisture, dirt, corrosion, fungus, and thermal shock. Curing at room temperature upon exposure to atmospheric moisture, its low viscosity allows versatile application via dipping, spraying, brushing, or automated selective coating equipment. It meets MIL-I-46058C military specifications and carries a UL 94 V-0 flame rating. Formulated with a UV indicator, it enables easy automated or visual inspection under blacklight. The 199.5 kg bulk drum is designed for high-tonnage continuous electronic manufacturing operations. |
| Key Features and Benefits |
| • Industrial Bulk Drum Supply (199.5 KG): Delivers maximum cost-efficiency and continuous supply for high-volume automated coating lines. • Industry & Military Standards: Qualified to MIL-I-46058C and UL 94 V-0 flame retardancy requirements. • UV Indicator: Fluoresces under UV light for easy quality control inspection of coating coverage and film uniformity. • 1-Part Convenience: Ready-to-use formulation compatible with dipping, spraying, brushing, and selective coating robots. • Flexible Elastomeric Film: Absorbs mechanical shock and thermal expansion stress, protecting delicate solder joints. • Robust Moisture Barrier: Provides exceptional long-term environmental sealing against high humidity and harsh atmospheric contaminants. |
| Technical Specifications |
| • Appearance / Color: Clear / Transparent (UV fluorescing) • Packaging / Net Weight: Industrial Drum / 199.5 KG • Chemical Base: 1-Part RTV Silicone (Solvent-borne) • Viscosity (@ 25°C): ~85-110 mPa.s • Tack-Free Time: ~7-10 Minutes • Hardness (Shore A): ~80 • Service Temperature Range: -65°C to +200°C (-85°F to +392°F) |
| Applications |
| • High-volume conformal coating of automotive electronics, ECUs, and under-the-hood sensor modules. • Aerospace, defense, and military-grade PCB assemblies requiring MIL-spec compliance. • Protection of industrial controls, inverters, power supplies, and heavy-machinery electronics. • Sealing outdoor LED lighting drivers and telecommunication base station circuitry. |
Usage Note: Substrates must be thoroughly cleaned and free of flux residues, moisture, and oils before application. Cures via reaction with atmospheric moisture; ensure adequate room ventilation. Viscosity can be adjusted using recommended DOWSIL™ thinners if necessary. Fully compatible with industrial drum pumps, selective coating machinery, dip tanks, and spray systems.
