Product Information
Full details
This Permatex Plastic Weld is a high-strength structural adhesive for general-purpose bonding of various materials like hard and soft plastics, composites, and wood. Its key benefit is forming a tough, durable bond that cures quickly, setting in 5-6 minutes and offering usable strength in 4 hours. A significant caveat is that it will not bond most polyethylene or polypropylene plastics.

FAQs
What types of plastic can this epoxy bond?
It bonds most hard and soft plastics. However, it is important to note that it will not bond most polyethylene (PE) or polypropylene (PP) plastics.
How long does it take to fully cure?
Usable strength is reached in approximately 4 hours at 72°F (22°C). Full strength may take longer depending on temperature and humidity.
Can I use this for outdoor repairs?
Yes, the epoxy is water-resistant and has good chemical resistance, making it suitable for many outdoor applications within its specified temperature range.
What is the maximum gap this epoxy can fill?
This adhesive can fill gaps up to 0.125 inches (approximately 3.175 mm).
How should I store the unused epoxy?
After use, re-attach the nozzle cap securely and store the syringe in its molded tray in a cool, dry place to maintain its integrity.
Do I need a primer before applying?
No, this product requires no primers for most compatible surfaces, simplifying the application process.
What is the temperature range for using this product?
The product is effective in a temperature range from -51°C to 121°C (-60°F to 250°F).
Troubleshooting
Adhesive not dispensing evenly
Ensure the syringe is held upright when preparing to dispense to allow air bubbles to rise. Ensure both components are at room temperature.
Bond is weak or fails
Verify that surfaces were properly cleaned, dried, and roughened. Ensure the adhesive was mixed thoroughly until evenly colored. Confirm the materials being bonded are compatible (not PE or PP).
Adhesive cures too quickly
Work in a cooler environment if possible. Prepare and mix only the amount of adhesive needed for immediate application, as the working time is limited.
Surface preparation is difficult
Use fine-grit sandpaper or an abrasive pad to lightly scuff smooth surfaces. Ensure dust and debris are removed after sanding.
Pros and Cons
Pros
- Forms a very strong and durable bond.
- Cures quickly for efficient repairs.
- Bonds a wide variety of plastic and non-plastic materials.
- Good resistance to water and chemicals.
- Can fill small gaps effectively.
- Works across a broad temperature range.
Cons
- Will not bond polyethylene or polypropylene plastics.
- Requires careful surface preparation for optimal adhesion.
- Mixing and application need to be done within the initial working time.
- Not suitable for flexible applications where extreme flexing occurs.
Setup, Compatibility & Care Instructions
Preparation is Key:
- Protect Work Area: Cover surfaces to prevent accidental drips or spills.
- Clean Surfaces: Ensure all surfaces to be bonded are clean, dry, and free from grease, oil, or contaminants.
- Roughen Smooth Surfaces: For optimal adhesion, lightly sand or abrade smooth surfaces to create a better grip for the adhesive.
Mixing and Application:
- Prepare Syringe: Remove the syringe cap. Hold the syringe nozzle upward and slightly pull back the plunger to allow any air bubbles to rise. Snap off and save the storage cap.
- Dispense Adhesive: Push the plunger to dispense equal amounts of resin and hardener onto a disposable surface like cardboard. The mixing paddle will emerge from the plunger.
- Mix Thoroughly: Use the provided paddle to mix the two components for two minutes until a uniform color is achieved.
- Apply: Apply a small amount of the mixed adhesive to one or both surfaces. Assemble the parts immediately.
- Clean Excess: Remove any excess epoxy that squeezes out right after assembly.
Curing:
- Usable strength is typically reached in 4 hours at 72°F (22°C). Cooler temperatures will extend the cure time.
Storage:
- After use, re-attach the nozzle cap securely and store the syringe in its molded tray in a cool, dry place.
Compatibility:
- Bonds most hard and soft plastics, composites, and wood.
- Important: This product will NOT bond most polyethylene (PE) or polypropylene (PP) plastics.
