It’s a synthetic PE polishing wax for natural high gloss finishes, same as for e.g. glossy tips of finished articles for the use in aqueous base and top coat formulations. In binder containing base coats the product reduces the tackiness of the finish and enhances the dry rub fastness properties.
EUDERM® X-tra Wax Pull Up
This highly effective product for the manufacturing of pull up articles can be applied on both full grain and corrected grain leather, either directly on the crust or on top of standard base coats depending on the required article. Thanks to its special composition it is also possible to achieve pull up effects even on pigmented leather.

It’s a versatile enzymatic ammonia-free bating product for a broad range of applications. Practical trials revealed a good opening up of the grain layer without sacrificing the grain tightness.
