Description

LOCTITE SI 5015 is a commercial-grade, blue acetoxy silicone adhesive sealant engineered to deliver robust, flexible gaskets and seals for heavy-duty industrial applications. Formulated to cure upon exposure to atmospheric moisture, this high-performance RTV (Room Temperature Vulcanization) silicone transforms into a highly resilient, flexible rubber seal that eliminates common points of failure along critical mechanical joins.

This professional sealant is specifically developed to withstand harsh operating parameters without hardening, shrinking, or cracking under intense thermal cycles, erosion, or aging.

Key Features & Benefits

High Thermal Stability: Maintains structural elasticity and operational integrity across an expansive engineering range from -54°C to +204°C.
Vibration and Load Management: Enhances bearing load capacities and elevates the shock absorption profiles of assembled joint areas.
Substrate Versatility: Direct adhesion onto a broad scope of industrial substrates, ensuring reliable sealing for stamped parts and variable metals.
Automotive Sensor Safe: Formulated to be completely safe for use with automotive oxygen sensors and sensitive electronics.
Efficient Form-In-Place Gasketing: Designed for total board replacement or precise board preparation, reducing inventory overhead for pre-cut gaskets.

Technical Specifications

Product Designation: LOCTITE SI 5015 (Superflex RTV Blue)
Chemical Base: Acetoxy silicone
Color: Blue
Curing Mechanism: Room Temperature Vulcanization (RTV) Moisture Cure
Operating Temperature Range: -54°C to +204°C
Optimal Storage Conditions: 8°C to 21°C
Primary Industrial Applications: Valve covers, transmission housings, gearboxes, differentials, water pumps, oil pans, and thermostat covers

Usage & Application Guidelines

Surface Preparation: All mating flanges and components must be thoroughly clean, bone-dry, and cleared of old gasket material, oils, and process grease before applying the RTV sealant.
Application Method: Apply a continuous bead of LOCTITE SI 5015 to one flange surface. Assemble parts immediately to ensure uniform wet contact before skin-over occurs.
Storage Protocol: To maintain nominal physical and chemical traits, store the product in its unopened container within the strict 8°C to 21°C window. Avoid extreme environments.

Frequently Asked Questions (FAQ)

What is the operational temperature range of LOCTITE SI 5015 Blue RTV?

LOCTITE SI 5015 is explicitly engineered to operate reliably within a thermal envelope of -54°C to +204°C. Its robust acetoxy silicone formulation prevents the material from hardening, shrinking, or cracking when subjected to continuous thermal cycling or environmental erosion.

Is LOCTITE SI 5015 safe for automotive oxygen sensors and electronic housings?

Yes. LOCTITE SI 5015 Superflex Blue is fully compatible and safe for use with automotive oxygen sensors. Its chemical design prevents sensor fouling, making it an ideal choice for sealing critical powertrain and engine components such as valve covers, water pumps, and oil pans.

What are the explicit industrial storage parameters to maximize the shelf life of this RTV sealant?

To avoid premature cross-linking or physical degradation, LOCTITE SI 5015 must be stored in its original, unopened packaging at a controlled temperature range between 8°C and 21°C. Storage outside of this specified range can permanently impair the product's curing and performance capabilities.
