Pangel® M90F is a high-purity smectite-based additive with a selected particle size, specifically designed to adjust the rheology of joint compounds, plasters, and fillers formulated in both powder and paste. It is recommended for applications requiring a fine particle size. Additionally, Pangel® M90F can serve as a binding agent for both organic and inorganic powders. Its high swelling capacity upon contact with water allows it to disperse easily while retaining high resistance when dry.

Instructions to Use

In dry products no special recommendation is required save that the mix is correctly homogenized. In ready-mix products, Pangel® M90F can be incorporated in the first phases of the dispersion together with other additives. It can also be incorporated with the organic thickeners before the addition of the load.


The dose of Pangel® M90F varies depending on the application. However, normal doses are between 1% and 3%.
