Overview

Built for the job.

Dual-Mix™ Quick Set 50 is a two-component, general purpose, urethane adhesive with a 50 sec set time designed for repair and bonding of most plastic, steel, aluminum, glass, SMC and fiberglass parts.

Dual‑Mix™ 40507 Quick Set 50 is a 2‑component urethane adhesive formulated for rapid bonding of structural and non‑structural components in collision repair. Designed for a 45‑second application window, it provides a high‑strength bond on a wide range of substrates including aluminum, steel, fiberglass, e‑coat, OEM plastics, and primed surfaces.

The formulation offers a 60‑minute work time and reaches sandable condition in 15 minutes, allowing technicians to prep and finish repairs efficiently. Full cure is achieved in 48 hours, delivering exceptional impact resistance and zero VOC emissions. The adhesive is supplied in a 7‑oz cartridge for precise dispensing.

Due to acute toxicity, carcinogenicity, and skin‑corrosive hazards, appropriate personal protective equipment—eye protection, chemical‑resistant gloves, protective clothing, and a respirator—must be worn. Operate in a well‑ventilated area and follow all H‑statements (H315, H317, H319, H332, H334, H335, H351, H373) for safe handling.
