Abstract
The object of the invention is to provide a non-aqueous fluorine containing surface treatment composition and treated textile. The surface treatment composition can be made into foam for low energy application and to control depth or penetration of surface treatment. Surface treatment can be applied by current commercially available foam application equipment, with excellent storage stability and performance characteristics as a surface treatment agent and is highly safe due to the non-flammability or flame retardancy. The composition should be environmentally friendly, a low energy process with limited negative impact to ozone layer depletion and global warming.
Claims18
A water and oil repellent composition for foaming process of a treated textile comprising:
- (A) a fluorine-containing polymer or copolymer,
- (B) a solvent component containing 5 wt. % or more of a chlorine-free, non-flammable halogen-containing solvent which has an ozone depletion potential (ODP) of 0.03 or less, a 100-year integrated global warming potential (GWP) value of 500 or less, and a kauri butanol (KB) value of 5 or more and a surface tension of 40 dynes/cm or less.
