Lohtragon® B61, based on Potassium Sodium Tartrate 4-hydrate, is an effective set retarder for gypsum and cement-based formulations. It enables precise control over setting time, improving workability, handling, and surface finish without compromising mechanical strength or durability.
Unlike conventional retarders, Lohtragon® B61 offers a predictable setting profile—ideal for large-scale projects or detailed applications such as precast elements and decorative plasterwork. It reduces waste and errors by allowing sufficient time for mixing and placement, even under varying environmental conditions.
Compatible with a wide range of systems, it integrates easily into formulations. Supplied as a high-purity, crystalline material, it ensures consistent dosing, stable performance, and excellent shelf life.
