3M 04747 Super-Fast Repair Adhesive, Amber, 47.3 mL Cartridge
Fast-Cure Plastic Repair Adhesive - 3M Super-Fast Urethane (04747, 47.3mL)
Revolutionary 60-minute full cure adhesive that transforms how professionals handle automotive and industrial bonding projects
When you need a plastic repair adhesive that delivers full cure in just 60 minutes instead of the typical 24-48 hours, the 3M 04747 Super-Fast Repair Adhesive changes everything. Its advanced amber urethane formula and breakthrough one-hour cure time let you complete repairs faster, delivering stronger, longer-lasting bonds that keep customers happy and reduce warranty callbacks.
Why Professional Technicians Choose Super-Fast 3M 04747 Repair Adhesive
60-Minute Complete Cure Time - Unlike competitors that require 24-48 hours, 3M 04747 reaches full cure in just one hour at room temperature, allowing you to sand, prime, and paint in the same day to dramatically improve throughput.
Advanced Plastic Compatibility - Engineered for modern automotive plastics including TPO, PP, PC, and ABS, its urethane chemistry flexes with substrates, preventing cracking and separation common with rigid adhesives.
Zero-Sag Precision Application - Thixotropic formula stays put on vertical and overhead repairs with gap-filling capabilities up to 1/8 inch, eliminating the need for backing materials on most jobs.
Professional-Grade Finish - Cures smooth for sanding and accepts all primers and topcoats, while the amber color provides visibility during application and disappears under paint for invisible repairs.

Professional Application Techniques for Best Results
Proper surface prep and technique ensure maximum bond strength. Follow these protocols:
Surface Preparation
- Clean: Remove contaminants with alcohol or degreaser.
- Sand: Use 120-grit for mechanical adhesion.
- Remove Debris: Eliminate loose material and dust.
- Dry: Ensure area is completely dry before applying adhesive.
Application Process
- Attach Nozzle: Twist on static mixer.
- Prime: Dispense onto scrap to verify mix.
- Apply: Work within 20-sec window, overfill slightly.
- Align: Hold parts for 30 sec to set initial gel.
- Cure: Maintain ≥70°F for fastest cure.
Expert Tips

Frequently Asked Questions About 3M 04747
How does this compare to super glue for plastic repairs?
3M 04747 maintains flexibility on automotive plastics, handles temperature cycling, fills gaps up to 1/8", and sands/paints professionally—unlike brittle cyanoacrylates that crack under stress.
Will it work on flexible bumper covers?
Yes. Specifically formulated for TPO and polypropylene bumpers, it flexes with the substrate, preventing cracks and separation under vibration while maintaining full structural integrity.
What temperature range can it withstand?
Once cured, it holds up from -40°F to 180°F, covering extreme weather and underhood heat cycles without losing strength or flexibility in automotive applications.
How many repairs per cartridge?
One cartridge handles roughly 20-30 small tab repairs or 10-15 medium cracks. Use the included mixers to maximize working time and material usage efficiency.
Can I paint over it, and when?
Yes—paint after 60-min cure at 70°F. Lightly sand with 180-220 grit before primer. Amber color disappears under paint for completely invisible professional repairs.
Is it safe for structural repairs?
It offers 2,500+ PSI tensile strength. For load-bearing parts, consult OEM specs and consider mechanical fasteners alongside adhesive for maximum safety and durability.
