Description
Quad® 420 is a new‑generation water‑reducing plasticising admixture incorporating Quad® technology. Developed using advanced hybrid polymer technology, it is designed to deliver high water reduction, extended slump retention, and homogeneous concrete performance across a wide dosage range.
Quad® 420 is particularly suited to ready‑mix concrete produced with high water demand aggregates. It provides robust and consistent concrete performance while supporting strength development, pumpability, and workability retention.
