3M’s Duramix 04240 is formulated for collision repair professionals working on plastic body parts. It provides strength, durability, and speed, especially helpful when repairing or reinforcing bumpers, tabs, and components subject to flex and impact.

Q: Is this adhesive suitable for plastic bumpers made from TPO or polypropylene?
A: Yes, with proper surface preparation and use of 3M Polyolefin Adhesion Promoter (PN 05907), Duramix 04240 adheres well to low surface energy plastics like TPO, PP, and ABS.

Q: How long after application can I sand and paint over the repair?
A: You can sand after about 15 minutes and paint (prime/paint) after about 30 minutes once the adhesive has cured sufficiently under normal conditions (around 70°F).

Q: What is the working temperature range, and how does temperature affect curing?
A: The service temperature range is from about -20°F up to 180°F. Higher temperatures should accelerate curing times, while colder temperatures may slow them. Ensure surfaces and environment are near room temperature (70°F) for optimal performance as per technical data.
