Loctite SI 5615 Silicone Sealant

Loctite SI 5615 Silicone Sealant is a 2-part, black silicone adhesive designed for industrial applications requiring fast curing and superior heat tolerance. This premium silicone-based bonding and sealing agent is engineered to withstand high temperatures of up to 180°C. Mixing Part A and Part B initiates the primary curing reaction. This is followed by a secondary cure with atmospheric moisture, forming a skin over the adhesive surface in approximately 12 minutes. Full cure is achieved within 7 days.

Loctite SI 5615 offers outstanding bond strength to both glass and metals, ensuring a secure and durable hold. Its thixotropic properties allow for precise application, even in challenging conditions. Loctite SI 5615’s heat resistance makes it ideal for applications in high-temperature environments, such as bonding glass stovetop assemblies and weld and rivet reduction.

• 2-part alkoxy silicone adhesive and sealant
• Fast curing time (12 min)
• High temperature resistance up to 180°C
• Excellent bonding strength to glass and metals
• Thixotropic

How to use Loctite SI 5615 Silicone Sealant:

1. For best results, bonding surfaces should be clean and free from grease and other contaminants. We recommend a general purpose cleaner such as Loctite SF 7063.
2. When using a new cartridge, remove cartridge cap and dispense a small amount of adhesive, making sure both parts A&B are extruding. Attach nozzle and dispense another 25 to 50mm before application.
3. Apply Loctite SI 5615 as soon as possible after mixing.
4. After dispensing the product, mate parts immediately to ensure maximum bond strength.
5. Allow for full curing time before subjecting to heavy service loads.

Storage

Store Loctite SI 5615 in the unopened container in a dry location. Optimal storage: 8°C to 21°C. Storage below 8 °C or greater than 28 °C can adversely affect product properties.
