Recommended Products for Face Masks

Tegotex® RT 2033

TEGOTEX RT 2033 is a reactive organic modified siloxane with an active content of 33 % in water, which is especially beneficial on cotton-based and cotton-blend products.

Handling

TEGOTEX® RT 2033 can be applied as a single component or in combination with other products, like extenders by the exhaust method or by padding. Due to its very small particle-size dispersion, TEGOTEX® RT 2033 is easily dispersible in water. Dosage depends on the type of fabric and the required performance. Product must be stirred gently at low shear rate before use.

To avoid foam formation during processing, we recommend using an adequate stirring process. Furthermore DYNOL® 360 as foam destabiliser can be added, either in product or in fleet before processing.
