| DOWSIL™ Q3-1566 Heat Resistant Adhesive Sealant – High-Temperature Silicone Elastomer |
| Product Description |
| DOWSIL™ Q3-1566 is a high-performance, single-component, heat-resistant silicone elastomer designed for bonding and protecting components exposed to high temperatures. It cures at room temperature (RTV) to form a flexible, durable, and dielectric barrier. |
| Key Features |
| • Temperature Resistance: Stable performance from -45°C to +200°C • Non-Slump Consistency: High viscosity for vertical or overhead applications • Electrical Safety: Excellent dielectric properties for electronic insulation • Curing: Room temperature moisture cure (RTV silicone) • Environmental Protection: High resistance to UV, moisture, and common chemicals |
| Applications |
| • Sealing and fixing of electronic components and power modules • Automotive engine and powertrain sealing applications • Thermal sealing for LED lighting and fixtures • Bonding in HVAC systems and industrial machinery |
| Advantages |
| • Remains flexible to prevent cracking under vibration or thermal cycling • One-part formulation eliminates mixing errors and simplifies assembly • Provides a reliable seal even in thick sections without flowing out • Long-term durability reduces maintenance and failure rates |
