Abstract: The present invention relates to a fluorochemical composition for rendering fibrous substrates oil repellent, water repellent and/or stain or soil repellent. Additionally, the invention also relates to fluorochemical compositions for providing stain release or soil release properties to fibrous substrates. In particular, the present invention relates to fluorochemical compositions that contain a fluorinated polyether compound that can be obtained by reacting an isocyanate component with a particular isocyanate reactive fluorinated polyether compound and a stain release compound. The invention further relates to a method of treating the fibrous substrate with the fluorochemical composition.
Abstract: Described is a free-radically curable composition comprising a fluoroalkyl silicone having at least two ethylenically unsaturated groups, a crosslinking agent having at least two ethylenically unsaturated groups, and a free radical initiator.
