What Is DOWSIL™ 732 Multi-Purpose Sealant?
DOWSIL™ 732 Multi-Purpose Sealant is a general-purpose, one-component silicone adhesive and sealant based on an acetoxy cure system. Once applied, it reacts with moisture in the surrounding air and cures at room temperature.
Available through New Tech, the product is designed for professional users who require a versatile silicone material capable of performing both sealing and bonding functions in suitable industrial applications.
After curing, the material develops into a tough and flexible silicone rubber that maintains its properties across a broad temperature range. This combination of adhesion, flexibility, temperature stability, and ease of application makes it suitable for a wide variety of industrial bonding and sealing tasks.
Unlike rigid bonding materials, this industrial silicone adhesive remains flexible after curing, making it particularly useful in applications where components may experience vibration, movement, or temperature changes.
Key Features and Benefits of DOWSIL™ 732
One-Part Formulation
DOWSIL™ 732 is supplied as a one-part adhesive/sealant, eliminating the need to mix separate components before application.
Room-Temperature Cure
The product cures at room temperature when exposed to moisture in the air, simplifying its use in general industrial applications.
Acetoxy Cure System
This silicone sealant multipurpose uses an acetoxy cure chemistry to develop a durable silicone rubber after curing.
Non-Sag Paste Consistency
Its paste-like, non-sag consistency helps the material remain where it is applied, making application more manageable on suitable joints and surfaces.

Through New Tech, industrial customers can integrate DOWSIL™ 732 into wider maintenance programs alongside adhesives, lubricants, cleaners, protective coatings, repair compounds, and other professional maintenance solutions.
Why Use a Multi-Purpose Silicone Sealant?
Industrial maintenance often involves different materials, changing temperatures, vibration, movement, and complex component geometries. A rigid material may not always be suitable when movement must be accommodated after curing.
A silicone sealant multipurpose formulation such as DOWSIL™ 732 provides a combination of properties that makes it useful across numerous applications:
- Strong and flexible cured rubber.
- Good adhesion to many substrates.
- Broad operating temperature range.
- Easy one-part application.
- No component mixing required.
- Non-sag consistency.
- Excellent dielectric characteristics.
- General-purpose bonding and sealing capability.
This versatility makes DOWSIL™ 732 a practical option for industrial plants, workshops, manufacturing operations, maintenance departments, and equipment assembly applications.
New Tech provides DOWSIL™ 732 as part of its professional range of industrial sealing and maintenance products for customers who need dependable solutions for ongoing maintenance and production requirements.
Industrial Bonding with DOWSIL™ 732
As an industrial silicone adhesive, DOWSIL™ 732 can be used where compatible components require bonding while maintaining flexibility after cure.
The cured silicone does not simply form a rigid connection. Instead, it produces a tough, flexible rubber capable of maintaining its properties across significant temperature changes.
This makes the product useful for suitable applications involving:
- Vibration.
- Thermal expansion and contraction.
- Temperature cycling.
- Flexible joints.
- General equipment assembly.
- Industrial maintenance.
Actual adhesion and suitability should always be confirmed for the specific substrate and operating conditions before full-scale application.
Industrial Sealing Performance
In sealing applications, DOWSIL™ 732 can be applied to suitable joints, gaps, and interfaces where a flexible silicone seal is required.
Once exposed to atmospheric moisture, the material begins curing and eventually forms a resilient silicone rubber.
Its non-sag consistency also helps control application, particularly where maintaining the applied bead is important.
Temperature Resistance of DOWSIL™ 732
One of the significant advantages of DOWSIL™ 732 Multi-Purpose Sealant is its broad temperature capability.
| Version | Continuous Stability and Flexibility | Short Temperature Peaks |
| Standard versions | -60°C to +180°C | Up to +205°C |
| Black version | -60°C to +205°C | Up to +230°C |
These temperature capabilities make the product suitable for many industrial environments where ordinary sealing materials may face significant thermal variation.
Actual application conditions should always be evaluated against the relevant product technical documentation.
Standards and Compliance
DOWSIL™ 732 is specified as complying with:
- MIL-A-46106
- FDA 21 CFR 177.2600
Compliance requirements should always be evaluated according to the specific application, regulatory requirements, and current technical documentation.

How to Apply DOWSIL™ 732 Multi-Purpose Sealant
Correct surface preparation and application help achieve consistent sealing and bonding performance.
Prepare the Surface
Ensure that the surfaces to be bonded or sealed are suitable for the product and properly prepared. Remove contaminants that could interfere with adhesion.
Apply the Sealant
Apply an appropriate bead of DOWSIL™ 732 Multi-Purpose Sealant to the required joint, gap, or bonding area.
Its non-sag paste consistency helps keep the product in position during application.
Assemble or Tool the Joint
Where bonding components together, position the parts as required. For sealing applications, tool the bead when necessary to achieve the required joint profile.
Allow Moisture Cure
DOWSIL™ 732 cures at room temperature through exposure to moisture in the surrounding air. Allow sufficient curing time before exposing the application to its intended operating conditions.
Application conditions, joint dimensions, temperature, humidity, and substrate characteristics can influence curing behavior.
DOWSIL™ 732 for Industrial Maintenance
Industrial maintenance teams frequently require materials that can perform more than one function. DOWSIL™ 732 provides both bonding and sealing capability in one product.
It can therefore complement other workshop and maintenance materials such as cleaners, lubricants, Multi-Purpose Oil, protective coatings, and repair compounds.
Its primary role, however, is as a flexible Silicone Sealant and adhesive for suitable industrial sealing and bonding applications.
As part of its industrial maintenance portfolio, New Tech provides DOWSIL™ 732 alongside complementary products that help workshops, factories, engineering companies, and maintenance teams manage different repair and maintenance requirements from a reliable source.
Choosing Between Clear, White, Black, and Aluminum
DOWSIL™ 732 is available in several colors, allowing the selection to reflect the appearance and operating requirements of the application.
Clear is useful where a less visually prominent seal is preferred.
White can suit applications involving light-colored components and finishes.
Black provides a dark finish and also offers the higher temperature capability specified for the black version.
Aluminum can provide an appearance better suited to certain metallic components and assemblies.
Color selection should therefore consider both appearance and, where applicable, performance requirements.
