Usage

Retardan®-2010 P provides excellent performance in the adjustment of setting time and workability of calcium sulphate binders, especially in neutral to slightly alkaline α- and β- Hemihydrate binders and allows the formulation of very low-emission mortar products. The product is especially suitable and designed for the following applications:
  • Gypsum patty and gypsum joint filler
  • Finest moulding and modelling plaster
  • Plaster application where working to feather edge is critical
 

Advantages

Retardan®-2010 P offers the following advantages:
  • Extremely fine filler for fine putties
  • Simple and accurate dosing at the dry mortar plant
  • Very effective set retarder for a variety of calcium sulphate binder types
  • Allows adjustment of the binder slurry’s setting-time to the needs of the manufacturing process
  • Compatible with a variety of calcium sulfate binder types and with other additives, such as Sika® ViscoCrete® superplasticizers
  • No reduction in the final strength of gypsum based products (unlike with several fruit acid based retarders)
  • Uniform and stable quality
  • Ecologically safe and as planned free from formaldehyde

Compatibility

Retardan®-2010 P may be combined with many other Sika products and most commonly used gypsum additives including superplasticizers, foaming agents / defoamers and stabilizers. In these combinations i.e. with Sika® ViscoCrete® superplasticizers, additional improvements in flow and setting-time adjustment can also be achieved.
Note: Always conduct trials before combining products in specific mixes and contact our Technical Services Department for additional information about specific combinations with other products.
Consumption

Recommended dosage

Typical dosage rage: 0.01 % - 0.2 % of dry weight.
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®-2010 P.
Note: Preliminary testing is required to determine the exact dosage for specific applications and conditions. Please contact our Technical Services Department for any additional information and assistance.
