3M 04247 Super Fast Plastic Repair is a viscous, clear duo‑pak resin designed for rapid structural and cosmetic repairs on ABS, plastic, and polyester substrates. The low‑viscosity formula fills gaps and rebuilds damaged panels, providing a smooth, sandable surface that blends seamlessly with surrounding material.
Key performance features include a 20‑second work time and a sandable window of 5 minutes, allowing technicians to finish a repair cycle in under an hour (1–4 hr cure depending on thickness). The cartridge delivers consistent flow for precise application, and the clear cure eliminates the need for tint matching on transparent or lightly colored parts.
Handling requires full personal protective equipment: eye protection, chemical‑resistant gloves, protective clothing, and a respirator when used in confined spaces. Ensure adequate ventilation; the formulation contains acute toxicity, aspiration, and carcinogenic hazards per the SDS.
