The CHT Group offers high-performance polysaccharides and functional additives for building materials and paints in the construction industry. Through our many years of experience in the modification of renewable raw materials, we provide products with outstanding property profiles. Our AGOCEL® product portfolio guarantees reliable processing and environmentally friendly optimization of mineral building material systems and architectural paints.
Rheological additives are essential components of paint and mineral building formulations. These are not only added to adjust the viscosity in order to meet certain processing requirements and specifications, but also to influence essential properties like storage stability and good anti settling behavior. Additionally, rheology additives help to adapt the product to the different application processes to guarantee the maximal performance and durability while minimizing costs.
CHT provides a wide range of sustainable rheological additives based on guar and xanthan gum to meet individual customer requirements. Swelling-retarded guar ethers are characterized in particular by their high water retention capacity, which prevents skin formation due to excessively rapid water evaporation. In addition, the modified guar ethers impart a balanced pseudoplastic behavior to the final formulations with excellent properties for both low and high shear forces.
In comparison, the complex xanthan gum molecule gives the products a rheological profile with an extremely high degree of pseudoplasticity. Due to this property, the desired final formulation exhibits excellent anti-settling behavior, thereby preventing formation of syneresis and improving the processing properties during troweling or spraying.
By combining sustainable CHT technologies, our customers can develop tailor-made formulations with excellent stability and the required application properties that meet the most modern ecological aspects.
Used as a single product, or in combination with other thickening systems, CHT rheological additives add significant value to your formulations:
