In the industrial landscape of boilers, furnaces, heat exchangers, and turbines, accurate temperature measurement is non-negotiable. The reliability of your sensors and thermocouples hinges on a secure, heat-resistant bond that won’t degrade under extreme thermal stress. Welding is often too complex or damaging, and conventional epoxies fail far below the required operating temperatures.
This is where advanced High Temperature Putty technology comes in. For industrial users seeking an unrivaled, durable, and easy-to-apply solution for bonding sensors in ultra-high heat environments, we recommend a superior product from the Incure Epo-Weld™ line.
Incure Epo-Weld™ HTCP-650 Ultra-High Temperature Ceramic-Fibre Thixotropic Sealant
Incure Epo-Weld™ HTCP-650 stands out as the best-in-class product for securing delicate temperature sensors and thermocouples in the most demanding applications.
| Key Performance Metric | Epo-Weld™ HTCP-650 Value | Benefit for Sensor Bonding |
| Max Service Temperature | Up to 1,300∘C (2,372∘F) | Offers the highest thermal headroom for extreme-heat furnace and turbine applications. |
| Composition | Ceramic and Fibre-filled Paste | Creates a stable, insulating, and dimensionally stable bond that resists thermal shock. |
| Formulation | Ultra-High Temperature, Thixotropic Sealant | Prevents sagging on vertical surfaces (like furnace walls or ducting) during application and cure. |
| Chemical Resistance | Excellent (No Effect) to most acids, salts, and organic fluids (fuel oil, gasoline, etc.) | Ensures the bond won’t deteriorate in corrosive industrial gas or fuel environments. |
Why HTCP-650 is the Superior Choice for Sensor Attachment
The unique formulation of Epo-Weld™ HTCP-650, a ceramic-fibre filled thixotropic paste, addresses the core challenges of high-temperature sensor installation:
1. Unmatched Thermal Stability
Operating in environments like boiler doors, manifolds, or molten metal systems requires a product that can handle continuous ultra-high heat. The HTCP-650’s 1,260∘C (2,300∘F) service temperature provides a critical safety margin over lower-rated products, ensuring your sensor maintains its position and bond integrity even during temperature spikes or extended operation.
2. Thixotropic and Easy Application
As a thixotropic paste, this sealant has a high viscosity when at rest, meaning it will not sag or run when applied to vertical surfaces or overhead positions—a common necessity when bonding sensors to ducting or furnace crowns. It’s supplied as a one-part system, simplifying application and ensuring consistent quality without the mixing errors associated with two-part products.
3. Protection and Insulation
For thermocouples, the putty not only provides mechanical adhesion but also offers electrical insulation and protects the sensitive “hot junction” from corrosive flue gases, abrasion, and potential short-circuits. This safeguarding is crucial for maintaining the accuracy and longevity of your temperature readings.
4. Simplified Cure Schedule
The recommended curing process is straightforward:
- First Cure: 3h at 25∘C (77∘F) or 3h at 95∘C (203∘F).
- Followed By: 1h at 95∘C (203∘F) (with a liquid binder, if extra moisture resistance is needed).
This allows for flexible installation, from ambient room temperature setting to a faster, heat-accelerated cure.
Ideal Industrial Applications for HTCP-650
The Epo-Weld™ HTCP-650 is specifically engineered for critical sealing and bonding tasks in:
- Furnaces and Ovens: Permanent attachment of internal thermocouples to refractory materials or metal housings.
- Steam Valves and Manifolds: Sealing and bonding where thermal cycling is severe.
- Ducting and Boilers: Securing surface-mount sensors for process control and efficiency monitoring.
- Heat Exchangers: Bonding sensors to monitor differential temperatures without compromising structural integrity.
When performance at the thermal extreme is your priority, the high-performance Epo-Weld™ HTCP-650 ceramic-fibre putty ensures your temperature sensors are securely bonded, insulated, and ready to deliver reliable data, even up to 1,260∘C. Trust in this solution to maintain your process accuracy and operational efficiency.
