LOCTITE^® SI 596 is a red, flowable, smooth, 1-part RTV (room temperature vulcanizing) acetoxy silicone paste sealant that cures at room temperature on exposure to moisture in the air to form a tough, flexible, waterproof, oil-resistant silicone rubber bond. It resists temperatures up to 316°C (600°F), making it well suited for sealing applications in industrial furnaces, ovens, boilers, exhaust stacks, high temperature ducting and heating elements in electrical appliances. It resists aging, weathering and thermal cycling without hardening, shrinking or cracking.

Features:

• High temperature, flexible adhesive/sealant
• Suitable for applications up to 316°C (600°F)

How to Use:

Ensure all surfaces are cleaned to remove any residual adhesives, oil and grease. Use LOCTITE^® SF 790 for easier removal of old adhesive residues. LOCTITE^® SF 7070 cleaner is recommended for general surface cleaning and degreasing prior to bonding.

Application:

Use supplied nozzle and, where appropriate, cut the end to give the desired bead size. Dispense adhesive bead(s) directly onto the surface to be bonded or sealed; parts should be assembled immediately to prevent partial curing and shimming. Prevent the assembled parts from moving during cure. For large areas where both substrates are impermeable to moisture, do not cover the complete bonding area with adhesive – allow some gaps for moisture to penetrate the bond line. Any remaining gaps can be filled once the adhesive has cured.
