| DOWSIL™ 3-0115 Automotive Sealant 22 KG |
| Product Overview |
| DOWSIL™ 3-0115 Automotive Sealant is a 1-part, non-slump, neutral-cure room temperature vulcanizing (RTV) silicone sealant engineered specifically for automotive powertrain and flange sealing applications. Curing at room temperature upon exposure to atmospheric moisture, it forms a durable, highly flexible elastomeric gasket designed to withstand engine oils, transmission fluids, and coolants. Packaged in a 22 KG pail for high-volume automated industrial dispensing, it provides excellent unprimed adhesion to machined automotive metal surfaces. |
| Key Features and Benefits |
| • Superior Fluid & Oil Resistance: Retains elasticity and bond integrity when in continuous contact with engine oils, transmission fluids (ATF), and glycol-based coolants. • Industrial 22 KG Pail: Designed for seamless integration with automated follower-plate dispensing pumps. • Non-Corrosive Neutral Cure: Safe for aluminum, cast iron, and steel flanges without inducing chemical corrosion. • Non-Slump Paste: Easily applied to vertical or intricate flange paths without sagging. • Thermal & Vibration Endurance: Resists severe temperature cycling and continuous engine vibration. • Unprimed Adhesion: Delivers robust adhesion to standard machined metallic surfaces without priming. |
| Technical Specifications |
| • Packaging / Net Weight: Pail / 22 KG • Cure System: Neutral (RTV) • Consistency: Non-slump paste • Skin-Over Time (@ 23°C, 50% RH): ~10-20 Minutes • Hardness (Shore A): ~35-45 • Service Temperature Range: -50°C to +200°C (-58°F to +392°F) with high-temperature peaks |
| Applications |
| • Automated sealing of engine oil pans, valve covers, and timing chain/belt covers in high-volume vehicle manufacturing. • Formed-In-Place Gasket (FIPG) robotic sealing for transmission cases, differentials, and axle housings. • Environmental sealing of oil pump, water pump, and thermostat housings on continuous assembly lines. • Heavy-duty mechanical flange joint sealing subject to high fluid and vibration stress. |
Usage Note: Ensure all flange surfaces are clean, dry, and free from old gasket residue, oil, or grease prior to dispensing. The 22 KG pail is designed for use with pneumatic follower-plate dispensing pumps. Fasten components to recommended torque specifications promptly after bead application.
