| DOWSIL™ 744 RTV Sealant White 20 L |
| Product Overview |
| DOWSIL™ 744 RTV Sealant White is a 1-part, non-slump, neutral-cure room temperature vulcanizing (RTV) silicone adhesive and sealant. Specifically engineered to deliver high adhesion strength on difficult-to-bond plastics, metals, and glass substrates. Its non-corrosive alkoxy cure mechanism makes it safe for sensitive electrical and electronic components. The 20 L pail packaging is ideal for high-volume automated industrial dispensing systems. |
| Key Features and Benefits |
| • High Unprimed Adhesion: Superior unprimed bonding to challenging engineering plastics, metals, and glass. • Non-Corrosive Neutral Cure: Safe for sensitive electronics, copper, and other metallic surfaces. • Industrial 20 L Pail: Compatible with automated follower-plate pumps and robotic dispensing lines. • Non-Slump Paste: Suitable for vertical and overhead applications without sag or slump. • Broad Service Temperature: Retains full flexibility from -50°C to +180°C (-58°F to +356°F). • Weathering Resistance: High tolerance against UV rays, moisture, ozone, and environmental weathering. |
| Technical Specifications |
| • Color: White • Packaging / Volume: Pail / 20 Liters • Cure System: Neutral Alkoxy (RTV) • Skin-Over Time (@ 23°C, 50% RH): ~20-30 Minutes • Tensile Strength: ~2.1 MPa • Elongation at Break: 600% • Hardness (Shore A): ~35 • Service Temperature Range: -50°C to +180°C (-58°F to +356°F) |
| Applications |
| • Bonding heavy-duty electrical components, transformers, and power supplies. • Appliance manufacturing including oven assemblies and white goods requiring high-elasticity joints. • Sealing plastic and metal enclosures, junction boxes, and terminal housings. • Elastic bonding for industrial equipment subject to physical movement and thermal stress. |
Usage Note: Ensure all substrate surfaces are clean, dry, and free from oil or grease. The 20 L pail is designed for use with pneumatic follower-plate dispensing pumps.
