Additives for Building Materials
With our advanced construction additives we offer solutions that enhance our customers' performance and value. Long-term relationships based on trust and face-to-face consulting is the basis of our work.
Integral water repellents for cement-based applications.
The use of TEGOSIVIN water repellents has a positive impact on the durability and the aesthetic properties of cement-based building materials. By the strong reduction of the water uptake and an excellent efflorescence control, negative effects will be avoided.
Liquid and powder performance additives for concrete and drymix applications.
Our SITREN and SITREN AirVoid product ranges contain different types of performance additives, mainly for cement-based applications. In addition to a broad range of liquid, powder defoaming and air entraining additives, for an optimized air control of concrete or drymix mortars, we offer different powder solutions for shrinkage reduction, water repellency and mold release.
Corrosion protection and oleophobic agent as part of mix design of steel reinforced concrete and special mortars
The in-situ corrosion protection properties and prolonged durability of Protectosil DRY CIT greatly improves the life cycle of concrete structures. Protectosil SC POWDER helps to maintain clean surfaces of high end mortars.
High purity fumed titania for photocatalytic concrete, urban pavements, façade mortars, plasters, tiles, roof tiles
Photocatalysis in the building industry offers promising potential. Surfaces coated with AEROXIDE TiO become self-cleaning and anti-bacterial. Furthermore, due to the very high photocatalytic activity of our products, photocatalytic oxidation of nitrogen oxides (NOx) and volatile organic compounds (VOCs) is one of the key properties provided for innovative building materials. In order to meet different requirements our product portfolio includes as well a highly dispersed fumed titania (AEROXIDE TiO 90), a granulated fumed titania (VP AEROPERL P 25/20) and dispersions thereof (AERODISP).
Processing aids for an optimized production of industrially produced building materials.
The production process of various building materials will be improved by our broad range of TEGO additives. Including: optimized foam control, better wetting, improved dispersing, leading to a higher process efficiency and better product performance.
AEROSIL, AEROXIDE, AERODISP, AEROPERL, SIPERNAT can enhance the performance, application and production processes of cement, mortars, concretes, gypsums, plasters as well as of construction additives
Many are the advantages that can be obtained by the right choice of our products. Some examples for cementitious systems are a faster and higher development of early strength, higher final compressive strength, improved homogeneity of component distribution, reduction of bleeding and segregation or stabilization of slurries and foams. Benefits for construction additives include, among others, improved processability during e.g. spray drying of emulsions/dispersions exhibiting thermoplastic behaviour, carrier of liquid additives for exact and controlled dosing, improved mixing efficiency and consistency in drymix formulations, stabilizations of dispersions by viscoelastic properties or stabilization of foams and emulsions by pickering effect.
Adhesion promoter between inorganic materials and organic polymers. Used in mineral fiber insulating materials, as additive to the binder system.
Functional Silanes are performance additives. Their main effects are: • surface modification of inorganic particles, fibers or substrates • adhesion promotion between inorganic material and organic resins • crosslinking of various resin types Main benefits are: • improved corrosion protection due to improved paint adhesion • improved mechanical strength, weather resistance, and moisture resistance
