PRODUCT DATA SHEET Retardan®-200 L Retarder for Calcium Sulphate (Gypsum) based binders DESCRIPTION Retardan®-200 L is a highly efficient liquid set retarder for calcium sulphate (Gypsum) based binders. The characteristics and advantages of Retardan®-200 L include: ▪ Highly efficient set retardation at very low dosages ▪ Allows adjustment of the binder slurry’s setting-time to the needs of the manufacturing process ▪ Compatible with a variety of calcium sulphate binder types and with other additives, such as Sika® ViscoCrete® superplasticizers ▪ Retardan®-200 L allows the preparation of large volume mixes and thus reduces the overall costs of the application ▪ No reduction in the final strength of gypsum based products (unlike with several fruit acid based retarders) ▪ Uniform quality ensures a stable manufacturing process and production running as well as uniformity and homogeneity of the final gypsum product ▪ Ecologically safe and free from formaldehyde USES Retardan®-200 L provides excellent performance in the control and adjustment of setting times and workability with calcium sulphate based binders. The product is especially suitable for the following applications: ▪ Production of gypsum boards (plasterboards / wallboards), fibreboards, ▪ partition panels, ceiling tiles & gypsum blocks PRODUCT INFORMATION Composition Aqueous solution of modified amino acid Shelf life 12 months shelf life from date of production if stored properly in undamaged, unopened, original sealed packaging.

APPLICATION INFORMATION Recommended dosage Typical dosage range in gypsum board production: 0.003 - 0.03 % by weight of binder. Differences in calcium sulfate binder type, raw material sources, calcining methods, age and storage conditions of the binder and other conditions and factors at the plant and/or on-site can also influence the setting time of gypsum binders and therefore the dosage requirements of Retardan®-200 L. Note: Preliminary testing is required to determine the exact dosage for specific applications and conditions. Please contact our Technical Services Department for any additional...
