Product Information
Full details
The Z-Poxy 30 Minute Epoxy (PT-39) is a high-strength, two-part adhesive designed for hobbyists, woodworkers, and RC enthusiasts who need a reliable, vibration-resistant bond. Its primary advantage is its ability to dry clear and remain flexible rather than becoming brittle over time, making it suitable for structural applications like engine mounts and model hull repairs. Users should be aware that the 30-minute cure time requires careful planning, as the working window is limited once the two components are mixed.

FAQs
Is Z-Poxy PT-39 waterproof?
Yes, it is highly resistant to moisture and fuel, making it suitable for both RC boat hulls and general outdoor use.
Can I use this for repairing plastic?
It works on many plastics, but it will not bond to low-surface-energy plastics like polyethylene or polypropylene.
How do I remove excess uncured epoxy?
Uncured epoxy can be cleaned up using denatured alcohol or a dedicated epoxy solvent.
Does it yellow over time?
Z-Poxy 30 Minute is designed to be clear and exhibits excellent resistance to yellowing compared to standard clear epoxies.
What happens if the ratio is slightly off?
For maximum strength, the 1:1 volume ratio is critical. If the mix is significantly off, the epoxy may remain tacky or fail to reach full structural hardness.
Can I paint over the cured epoxy?
Yes, once fully cured, the surface can be sanded and painted or primed.
Troubleshooting
Epoxy remains sticky after 30 minutes
This is normal; the product has a 30-minute working time and requires several hours to fully cure to a hard finish.
Uneven or messy application
Use masking tape around the bond area to create clean lines and remove tape while the epoxy is still tacky.
Bond failed to hold
Ensure the surfaces were not contaminated with oil, grease, or wax prior to application. Lightly sanding smooth surfaces can improve mechanical adhesion.
Pros and Cons
Pros
- Dries completely clear for clean aesthetics
- Does not turn brittle with age
- Excellent resistance to vibration and fuel
- Easy 1:1 mixing ratio by volume
- Generous 8oz total capacity
Cons
- Longer cure time compared to 5-minute epoxies
- Not suitable for use on certain low-surface-energy plastics
- Requires proper ventilation during application
Setup, Compatibility & Care
To achieve the best results, ensure all surfaces are clean, dry, and free of oil or dust. The epoxy is mixed by combining equal parts of the resin and hardener by volume. Use a clean, non-porous surface or a mixing cup to blend the two parts thoroughly until the color is uniform.
- Application: Apply with a brush, spatula, or syringe depending on the scale of the task.
- Curing: Allow the bond to set for at least 30 minutes. Full structural strength is typically achieved after a 24-hour cure period at room temperature.
- Compatibility: Compatible with most rigid substrates such as metal, ceramic, wood, and fiberglass. Note that it is not recommended for polyethylene or polypropylene plastics.
- Care: Keep bottles tightly capped when not in use and store in a cool, dry area away from direct sunlight.
