DOWSIL™ 736 RTV Silicone Sealant Red 300ml – High Temperature

DOWSIL™ 736 RTV Silicone Sealant Red 300ml – High Temperature

For industrial assemblies exposed to elevated temperatures, ordinary silicone sealants may not provide the required performance. DOWSIL 736 RTV Silicone Sealant is a high-temperature red RTV adhesive/sealant developed for applications where sealing, bonding and encapsulation must withstand demanding thermal conditions.

This one-part silicone sealant provides a non-sag formulation that can be applied to side walls and overhead surfaces without excessive running. Dow identifies DOWSIL 736 for applications requiring performance at temperatures up to 600°F (315°C).

DOWSIL 736 RTV Silicone Sealant for High-Temperature Applications

DOWSIL 736 RTV Silicone Sealant is designed for critical bonding, sealing, potting, encapsulating and protective-coating applications where elevated temperature performance is required.

Dow specifies continuous exposure capability up to 260°C (500°F) and intermittent exposure up to 315°C (600°F). This makes the product suitable for selected high-temperature industrial applications where conventional general-purpose sealants may not be appropriate.

The actual suitability of the sealant should always be evaluated against the application’s temperature cycle, substrate, joint design and exposure conditions.

Non-Sag and Non-Flowing Performance

One of the useful characteristics of DOWSIL 736 RTV Silicone Sealant is its ability to remain in position after application. Dow describes the product as a sealant that will not sag or run, allowing it to be applied on vertical and overhead surfaces.

This characteristic is particularly useful for industrial equipment, heating assemblies, oven components and other installations where the sealant must remain where it is applied during curing.

Industrial Oven and Heating Element Sealant

DOWSIL 736 is specifically listed by Dow for sealing and encapsulating heating elements in appliances and for use with industrial ovens. It is also identified for moving oven belts and other high-temperature sealing applications.

Potential applications include:

• Industrial ovens
• Heating elements
• Appliance heating assemblies
• Oven belts
• Fired heaters
• Access doors
• Flanged pipe joints
• Gas-appliance flues
• Bag filters on smokestacks
• High-temperature equipment
• Industrial electrical/electronic equipment
• High-temperature gasketing

The product can therefore be useful where a flexible silicone seal is required around components exposed to significant heat.

Aerospace Gasketing Applications

Dow specifically lists aerospace gasketing among the applications for DOWSIL 736.

For aerospace, defence or other specification-controlled applications, customers should verify the exact product qualification, certification and current technical requirements before use. Product suitability should be determined by the relevant engineering specification rather than by temperature rating alone.

One-Part RTV Silicone Formulation

DOWSIL 736 is a one-part RTV adhesive/sealant, which means it is supplied ready for application without requiring the user to mix two components before use. Dow’s current product information identifies the product as one-part.

This makes the material practical for maintenance, repair, assembly and production applications where straightforward dispensing and application are important.

High-Temperature Silicone Performance

The cured material combines high-temperature resistance with the flexible characteristics expected from a silicone sealant.

Dow’s current product information lists typical properties including approximately 26 Shore A hardness, 600% elongation and 348.1 psi tensile strength. These values are typical properties rather than guaranteed specifications and should not be treated as production acceptance limits.

The combination of flexibility and temperature resistance can help the sealant accommodate movement and thermal cycling in appropriately designed joints.

Red RTV Silicone Sealant

The red colour makes DOWSIL 736 easy to identify in an assembly and is characteristic of this high-temperature sealant product.

The DOWSIL 736 RTV Silicone Sealant formulation is intended for demanding applications rather than general household sealing. It is especially relevant to industrial users working with heating systems, ovens, appliances and high-temperature equipment.

Typical Industrial Applications

Industrial Ovens

Use in suitable sealing and gasketing applications associated with industrial ovens and high-temperature equipment.

Heating Elements

Dow specifically identifies sealing and encapsulating heating elements in appliances as an application.

Fired Heaters

The product can be considered for suitable sealing applications around fired-heater assemblies and associated components.

Oven Belts

DOWSIL 736 is specifically listed for moving oven belts, making it relevant to selected continuous industrial heating processes.

Aerospace Gasketing

The product is listed by Dow for aerospace gasketing applications, subject to the appropriate engineering and qualification requirements.

High-Temperature Industrial Sealing

It can also be considered for critical bonding, sealing, potting, encapsulating and protective-coating applications where the component must operate at elevated temperatures.

300ml Package

This listing is for the 300ml package of DOWSIL 736 RTV Silicone Sealant.

A 300ml package is convenient for professional maintenance, assembly and industrial sealing work where a larger quantity than small consumer tubes is required.

Always verify the exact cartridge/tube configuration and dispensing compatibility with the supplied package before ordering.

Application Considerations

Before applying DOWSIL 736 RTV Silicone Sealant, surfaces should be properly prepared according to the manufacturer’s technical documentation and the requirements of the specific application.

Temperature resistance does not mean that every joint can automatically operate continuously at the maximum temperature. Joint geometry, substrate, exposure duration, thermal cycling, mechanical stress and environmental conditions all influence actual performance.

For critical industrial, aerospace or high-temperature applications, review the current Dow technical documentation and perform compatibility testing where required.

The product should be stored, handled and applied according to the manufacturer’s current technical and safety documentation.
