Set Retarder

ST-302

Set Retarder ST-302 is a chemical admixture formulated to control and extend the setting time of cement-based mixtures such as concrete and mortar. Its precise composition slows down the hydration process, allowing longer workability and placement time without affecting final strength or durability.
