AIR-ENTRAINING AGENTS

Materials that increase the air content in a way that improves workability, reduces material costs and saves on energy costs.

MORE

AD MIX

  • Sitren AirVoid 601

Anionic air-entraining agent for construction applications such as concrete, mortar and plaster.

 

DRY MIX

  • Sitren AirVoid 561

Amphoteric surfactant powder for bubble generation in construction materials.

DEFOAMERS

Additives that remove air trapped within a formulation, improve impermeability, durability and hardness.

MORE

AD MIX

  • Sitren AirVoid 312

Silicon-free surfactant recommended for defoaming polymeric systems. Compatible with superplasticisers such as lignosulfonates and polycarboxylates.

 

DRY MIX

  • Sitren AirVoid 362

Polyether-based defoamer powder in inorganic filler.

DEMOULDING AGENTS

Concentrated emulsion to remove concrete pieces from steel moulds.

MORE

  • Sitren MR 870

Vegetable oil in emulsion.

SHRINKAGE AND CRACK REDUCERS

Reduce surface tension by improving cement wetting, in a way that water hydrates it correctly. This allows to maintain a thinner pore structure due to the cracking reduction during the drying process.

MORE

AD MIX

  • Sitren SRA L 210

Polyether-based liquid shrinkage reducer. Significantly reduces drying shrinkage and cracking.

 

DRY MIX

  • Sitren PSR 100

Modified glycol in inorganic filler to reduce shrinkage.

WATER REPELLERS

Reduce water penetration and give a peeling effect, also reducing the formation of saltpetre and providing better protection.

MORE

AD MIX

  • Tegosivin CA 880

Water repellence and efflorescence control based on alkoxy functional silanes.

 

DRY MIX

  • Sitren P 750

Highly efficient water repellent, based on a silanes and siloxanes mixture.

WETTING AGENTS

Surfactants that decrease surfase tension allowing water to cover more easily the particles in the formulation.

MORE

DRY MIX

  • Surfynol 500 S

Helps color development in pigmented systems and reduces mixing time.
