Devcon Fast Curing Putty for Industrial Maintenance
Industrial repairs often require materials that minimize maintenance delays while providing a durable, machinable finish.
Devcon fast curing putty is designed to set rapidly and allow subsequent machining after sufficient curing. Its steel-filled formulation makes it suitable for rebuilding damaged metal surfaces and restoring components that require additional shaping.
The product reaches full cure in approximately 16 hours under the specified conditions. Machining may begin after at least one hour when the material has developed sufficient hardness and the manufacturer’s instructions permit it.
For applications requiring a fast set metal epoxy, Devcon SF offers an option for suitable repair work where curing time and machinability are important considerations.
Super Fast Steel Epoxy for Metal Rebuilding
This super fast steel epoxy is formulated to fill damaged areas and rebuild metal surfaces that require further finishing.
Its putty consistency makes it easy to work into repair areas and helps maintain the applied shape on vertical surfaces.
Once adequately cured, the material can be machined to obtain the required dimensions and metallic finish.
Common restoration tasks include patching castings, repairing pump and valve bodies, and rebuilding suitable bearing components.
How to Apply Devcon Plastic Steel Putty SF 500g
Correct surface preparation, mixing, application, and curing are essential for achieving satisfactory repair results.
Always follow the manufacturer’s technical instructions and specified resin-to-hardener mixing ratio.
Step 1: Prepare the Repair Surface
Inspect the damaged component and remove loose material, grease, oil, and other contaminants according to the manufacturer’s surface preparation instructions.
Confirm that the substrate and operating conditions are suitable for an epoxy repair.
Step 2: Mix the Epoxy Putty
Mix the resin and hardener thoroughly using the specified mixing ratio until a uniform consistency is achieved.
For large industrial containers weighing 25 lb, 30 lb, or 50 lb, the supplied application guidance recommends a T-shaped mixing paddle or a propeller-type Jiffy Mixer Model ES attached to an electric drill.
Move the mixing tool vigorously up and down until the resin and hardener form a homogeneous mixture.
For the 500g package, use the mixing procedure specified for that package.
Step 3: Apply the Mixed Material
Spread the mixed putty over the repair area and press it firmly into the substrate to maximize surface contact.
Work the material into the damaged section to fill suitable cavities and irregularities.
Step 4: Assemble the Components
When bonding mating parts, assemble them within the recommended working time.
Apply firm pressure to minimize gaps and ensure good contact between the surfaces.
A small amount of epoxy flowing out around the edges indicates that the gap has been filled.
Step 5: Allow the Material to Cure
Allow the epoxy to cure according to the specified conditions.
Devcon Plastic Steel Putty SF reaches full cure in approximately 16 hours, after which it can be machined, drilled, or painted as directed.
Do not return repaired equipment to service until the required curing and repair acceptance criteria have been met.
Repairing Large Gaps and Holes
When repairing large gaps or holes, additional reinforcement may be necessary to support the epoxy.
The supplied application instructions recommend placing one of the following between the repair area and the putty before application:
- Fiberglass sheet.
- Expanded metal.
- Suitable mechanical fasteners.
Select the reinforcement method according to the repair design and the condition of the component.
Applying Devcon SF to Vertical Surfaces
The putty consistency makes Devcon plastic steel putty SF suitable for vertical repair applications.
It can be troweled onto vertical surfaces at a thickness of up to ¼ inch (6.4 mm) without sagging under the specified conditions.
This property is useful when repairing suitable equipment housings, castings, and other components that cannot be positioned horizontally.
Curing Time and Temperature Considerations
Temperature affects both the working time and curing behavior of epoxy materials.
At approximately 70°F (21°C):
- Temperatures below 70°F (21°C) increase working time and functional curing time.
- Temperatures above 70°F (21°C) reduce working time and functional curing time.
For maximum physical properties, the supplied instructions specify the following curing procedure:
- Cure at room temperature for 2.5 hours.
- Follow with heat curing for 4 hours at 200°F (93°C).
Use this procedure only when the component and repair conditions allow it, and follow the manufacturer’s technical guidance.

Chemical Resistance and Product Limitations
Devcon SF provides resistance to many chemicals, including most acids, bases, solvents, and alkalis.
However, the product is not recommended for long-term exposure to concentrated acids or organic solvents.
Chemical compatibility depends on the specific substance, concentration, temperature, exposure duration, and operating environment.
The end user is responsible for determining whether the product is suitable for the intended application and repair process.
