Retardan®-2010 L
Retarder for Calcium Sulphate Binders
Retardan®-2010 L is a liquid high-performance set retarder for calcium sulphate based bound materials.
- Very efficient at low dosages
- Uniform and proven quality
- Ecologically safe and EC1 plus suitable
Usage
Retardan®-2010 L provides excellent performance in the adjustment of setting time and workability of calcium sulphate based binders. The product is especially suitable for the following application fields:- Fabrication of gypsum boards (plasterboards / wallboards), fibreboards, partition panels, ceiling tiles & gypsum blocks
- Ready-mix production of floor screeds & self-leveling screeds based on calcium sulphate binders
Advantages
The benefits of Retardan®-2010 L include, but are not limited to the following:- Very efficient set retardation, already at low dosages
- Allows the setting-time adjustment of the binder slurry to the needs of the manufacturing process
- Compatible to a variety of calcium sulphate binder types and to other additives, such as Sika® ViscoCrete® superplasticizers
- Retardan®-2010 L allows the preparation of large mixes and thus reduces the application costs
- No reduction of final strength of gypsum products (unlike several fruit acids)
- Uniform quality ensures a stabile manufacturing process run as well as uniformity and homogeneity of the final gypsum product
- Ecologically unproblematic, free of formaldehyde

Application
Compatibility
Retardan®-2010 L may be combined with many other Sika products as well as with most commonly used gypsum additives, like superplasticizer, foaming agent/ defoamer and stabilizer. In combination i.e. with Sika® ViscoCrete® superplasticizer improvements in flowability and setting-time adjustment may be achieved.
Note: Always conduct trials before combining products in specific mixes and contact our technical service for information about specific combinations with Sika® products.
Dispensing
Retardan®-2010 L is added to the gauging water. When used in very low dosage (i.e. during gypsum board production), Retardan®-2010 L may be pre-dissolved in pure water for easier dosing. Please contact our technical service for more information and assistance.
Recommended Dosage
Typical dosage range in gypsum board production: 0.03 - 0.3 % by weight of binder. Differences in calcium sulfate binder type, raw material sources, calcining methods, age and storage conditions of the binder and other individual parameters at the plant and/or job site can influence the setting time of gypsum binders and therefore the dosage of Retardan®-2010 L.
Note: Preliminary testing is required to determine the exact dosage for your specific conditions. Please contact our technical service for more information and assistance.
