Tin sulphate – persistently effective

Since 2005, only cements and mortars showing a soluble hexavalent chromium content of less than 2 ppm may be marketed in the European Union. This guideline value is prescribed by European Directive 2003/53/EC for reasons of occupational safety. TIB Chemicals offers the appropriate products for this purpose: Our additives for cement and mortar formulations are based on tin sulphate as the active ingredient to reduce the hexavalent chromium content effectively and sustainably. To suit various customer requirements, TIB Chemicals offers a whole range of redox products based on tin sulphate, which differ in active ingredient content and flowability. The advantage over alternative iron-based active ingredients:

 

Tin sulphate inhibits the reoxidation of the resulting trivalent chromium species. Therefore, the respective cement or mortar formulation fulfils the required limit value for hexavalent chromium significantly longer. In addition, chromate reducers based on tin sulphate are colour-neutral – and therefore ideally suited for decorative applications such as stuccos and plasters. Another plus: Tin sulphate is already highly effective at significantly lower dosage rates. Thanks to the variable flowability of our Redox products, they can be added effectively under a wide variety of conditions. The application properties of the respective cement or mortar formulation remain unaffected.

Our products
in the range Hexavalent Chrome Reduction

TIB Chemicals offers a comprehensive range of highly specialized chromate reducers specifically developed for the construction industry.

 

Our products meet the stringent requirements of the European Directive 2003/53/EC, which mandates that cements and mortars in the EU must have a soluble hexavalent chromium content of less than 2 ppm.

 

Our additives for cement and mortar formulations are based on the active ingredient tin sulfate, which effectively and sustainably reduces the hexavalent chromium content. The significant advantage of tin sulfate over alternative iron-based active ingredients lies in its inhibition of the reoxidation of the resulting trivalent chromium species. This ensures that the cement or mortar formulation maintains the required limit for hexavalent chromium over an extended period.

 

Our redox products are color-neutral, making them ideal for decorative applications such as stucco and plaster. Thanks to their high effectiveness at low dosage rates, they offer a cost-efficient solution for the construction industry. The variable fluidity of our products allows for easy and flexible integration into various production processes without impairing the application properties of the cement or mortar formulation.

 

TIB Chemicals stands for quality and innovation in the chemical industry. Our tin sulfate-based chromate reducers not only ensure compliance with legal requirements but also offer sustainable and efficient solutions for the construction industry. Rely on our expertise and experience to make your construction projects safe and environmentally friendly.
