2K hardener for U-POL primers, clears and solid colors
U‑POL® SYSTEM 20 UP2323 is a clear, liquid hardener formulated for use with 2‑K primers and clearcoats in automotive refinishing. It meets the National Rule Standard, providing a reliable catalyst for high‑performance coating systems where a consistent, durable finish is required.
The hardener is compatible with primer substrates and is supplied in a 1 L tin, offering a shelf life of one year when unopened. Its formulation supports uniform cure across the coated surface, ensuring the intended hardness and chemical resistance of the topcoat.
Due to its classification for acute toxicity, flammability, and other hazards, appropriate personal protective equipment—including eye protection, gloves, protective clothing, and a respirator—must be used. Work in a well‑ventilated area and observe all H‑statements (H225, H226, H304, H312, H315, H317, H332, H335). In case of exposure, follow the first‑aid procedures outlined in the SDS.
