Our expertise – interfacial phenomena within the construction industry

Our four management systems address the specific

requirements of the construction industry, such as:

• Performance

• Durability

• Lifecycle management

• Appearance

• Resource efficiency

• Cost efficiency

• Eco-friendliness

Our brands: SITREN®

SITREN AirVoid®

TEGO® Antifoam

AirVoid Management – Control air with our air entrainers and defoamers

Air in mortars has a direct impact on:

• Workability

• Mechanical properties

• Durability

• Aesthetics

• Slump properties

• Insulation properties

• Density

Entrained air has a significant impact on the performance of cement and gypsum based building materials, e.g. improvedworkability of renders, dense surface of SLUs. Our new powder additives portfolio combines the expertise and the chemicalknow-how of two well established partners* in the drymix industry.

Water repellents are used to provide mortar and rendering systems with durable protection against water and moisture.SITREN® P 730 and SITREN® P 750 minimize the infiltration of water and dissolved pollutants, while maintaining the

water vapor permeability at the same time.

Shrinkage reducing agents are used to limit the crack formation and deformation of cementitious based mortars.SITREN® SRA P 260 and SITREN® P 105 efficiently reduce pore water surface tension and hence capillary pressure andassociated structural stress. The new SITREN® SRA product line allows mortars to meet the most stringent eco label

requirements such as EMICODE EC1PLUS – without any dosage restrictions.
