Clariant launches solvent-free finish

7 September 2010

Clariant offer leather finishers a solvent-free alternative to nitro cellulose (NC) emulsions with the launch of Aqualen Top IL, an aqueous, modified polyurethane dispersion.

Aqualen Top IL is an aqueous intermediate lacquer, especially developed to substitute solvent-containing emulsion lacquers. It is easy to use, in the same way as standard NC-emulsion lacquers without changes to application or procedure and without the use of solvents. As a result, solvents are eliminated from exhaust air and no solvent smell remains in the leather. NMP-free with very low VOC levels, Aqualen Top IL reduces emissions in tanneries, ensuring further environmental and health-related benefits.

Aqualen Top IL is applied onto the base coat to eliminate tackiness when piling, milling or embossing the leathers. The excellent plate release and subsequent milling behaviour offered by Aqualen Top IL ensures a trouble-free production process. Aqualen Top IL is mainly for use on furniture and automotive leathers.
