Laponite RDS

Coatings industry
Special features and benefits
Laponite RDS increases viscosity in the low shear range with a low impact in the high shear range. It improves processability and storage stability. It is also highly effective in preventing the settling of pigments, extenders, matting agents, or other solids used in aqueous coating systems.

Recommended levels
0.1–2.0% additive (as supplied) based upon total formulation.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.

Incorporation and processing instructions
To ensure optimum distribution and the best possible effectiveness and reproducibility in applications,  Laponite RDS must be fully hydrated in water with a low ion concentration (20 °C ± 5 °C). Therefore, Laponite RDS is gently added to the water and dispersed whilst continuously stirring at high speed. The dispersion can be used as soon as it is clear and no undispersed particles are visible. For optimum processibility, it is recommended to prepare a dispersion of Laponite RDS with a solids content of up to 10% in water.
Special note
Laponite RDS is a synthetic layered silicate. It hydrates and swells in water to provide translucent and colorless colloidal liquid dispersions known as sols. At a solids concentration of 10 % in water, these will remain free flowing for up to 24 hours.

Multi-Color-Paints (MCP)
Special features and benefits
Laponite RDS is a synthetic phyllosilicate that is highly recommended for formulating Multi-Color-Paints (MCP). Multi-Color-Paints are specially designed aqueous paints in which different colors co-exist as fully separated paint droplets. Laponite RDS is highly recommended for formulating the white or transparent base paints.
Recommended levels
4.0–6.0% additive dispersion (7% in demineralized water) based upon base paint.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.

LAPONITE-RDS is a synthetic layered silicate. It hydrates and swells in water to provide translucent and colorless colloidal liquid dispersions known as sols. At a solids concentration of 10% in water, these will remain free flowing for up to 24 hours.

Construction chemicals
Properties and advantages
The use of Laponite RDS leads to shear thinning rheological behavior and can be adjusted from thixotropic to pseudoplastic flow behavior of construction chemical products depending on the amount used. The additive is particularly suitable for spray applications, for example in dispersion-bound building material formulations such as putty compounds. It improves the storage stability and anti-settling properties of the system. Laponite RDS can also be used as a stabilizer in anionic bitumen emulsions. It increases the viscosity of the dispersing medium and thus has an emulsion-stabilizing effect.

Recommended levels
0.5–5.0% additive dispersion (10% in water) based upon total formulation.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
To ensure optimum distribution and the best possible effectiveness and reproducibility in applications, Laponite RDS must be fully hydrated in water with a low ion concentration (20 °C ± 5 °C). In order to achieve the best processibility, it is recommended to prepare a dispersion of Laponite RDS with a solids content of up to 10% in water. This also allows subsequent addition as a post-additive. Direct addition as a powder, especially in mineral binder systems (premixed dry mortars), is not recommended.

Adhesives and sealants
Special features and benefits
Laponite RDS increases viscosity in the low shear range with a low impact in the high shear range. It improves processability and storage stability. It is also highly effective in preventing the settling of fillers, pigments, matting agents, or other solids used in aqueous adhesives and sealants.

Synthetic (modified) phyllosilicate

Laponite RDS is hygroscopic and should be transported and stored dry in the unopened original container at temperatures between 0 °C and 30 °C.
