Lanxess expands range of finishing products
02/07/2009
Specialty chemicals group Lanxess has added two new soft acrylic base coat resins to its range of finishing products.
The two waterborne polyacrylate dispersions Primal SB-110 and Primal SB-155 are manufactured by The Dow Chemical Company and marketed by Lanxess AG’s Leather business unit.
The two companies say the acrylic emulsion Primal SB-110 is a technology advancement from the successful Primal SB-100, offering improved embossing properties, fastness to heat yellowing, cut-through resistance and lower surface tack. The product can be used to produce base coats for very soft leathers that are characterised by high wet and dry flex resistance, good print retention, good filling and covering properties.
For a binder of this softness it has remarkably low tack and good plate release. Leathers base-coated with a formulation containing Primal SB-110 also retain more of their inherent softness, Lanxess has said.
Compared with its successful predecessor, Primal SB-150, the new, advanced polyacrylate chemistry of the Primal SB-155 has improved cut-through resistance, better fastness to heat yellowing and lower surface tack. It is a soft acrylic base coat binder with optimised embossing properties. The product is particularly suitable
for high-covering base coats for embossed leather types.
Base coats formulated with this binder are particularly resistant to cut-through when embossed at high temperatures and pressures, especially on empty crust leathers.
The marketing agreement concluded between Lanxess and Rohm and Haas in 1997 will now be continued with Dow. This agreement concerns the provision of technical service and the marketing of product ranges such as Primal, Hydrholac, Leukotan, Lubritan and Rosilk.
The Leather business unit is part of Lanxess’s Performance Chemicals segment, which posted sales of EUR 1,930 million in fiscal 2008.
