CT TETRAHYDROFURFURYL ALCOHOL (THFA)®
QO Tetrahydrofurfuryl Alcohol (THFA) makes possible spray-dyeing of full-grain leather for two reasons. First, QO T H F A is an excellent solvent for a wide range of dye types including acid, basic, and direct. Secondly, T H F A is a very efficient driver carrying the dye through the grain of the leather without disturbing the fat liquor balance necessary for flexibility and "feel". The combined action of T H F A as a penetrant and dye solubilizer permits spray-dyeing of full-grain leather in deep and even color shades. The depth of color obtained using THFA is equivalent to that achieved in drum-dyeing. T H F A serves as a useful adjunct in flame-coating of corrected grain leather by giving a more evenly dyed undercoat. As a result, fewer pigment-finish coats are necessary thus preserving the true character of the leather. T H F A is also used as a penetrant for resin-finish coats to aid resin penetration and adhesion to leather surfaces. Investigate the advantages of QO T H F A in dyeing. Write for a sample and a copy of Bulletin 206. Watch our ads for benefits of QO T H F A in other industries.
