- Application Details
If water-based formulations of SIPELLĀ® RE 63 F are made, care needs to be taken on the selection of the emulsifier to avoid effect reducing hydrophilicity. The application of the formulated water repellents is recommended in the wet-end process. Pre-tests are recommended in order to avoid incompatibility with the fat liquors.

SIPELLĀ® RE 63 F is used as a basic material for the formulation of water-based water repellents, especially for the wet-end application on leather. The epoxy function is suitable to react with nucleophilic groups of the protein matrix. Especially amino as well as hydroxyl and mercapto groups could react to form a chemical bonding with the epoxy function of the silicone. The water repellent effect is therefore not dependant on chromium tanned leather.
