Mainly designed for footwear and leather goods, the new series of pigments suitable for metal-free leather finishing proposed by GSG Group is the result of a long research aimed at achieving the highest environmental standards. “The pigments that compose the metal-free range have been developed by selecting the highest quality raw materials and reducing, where possible, the environmental impact in compliance with the ZDHC MRSL v.2.0 guidelines – explains the Venetian company – In particular, they have been studied to minimise problems in reproducing the desired shade and are tested with multiple binders based on acrylic and polyurethane”.
An innovative range that obviously represents a valid alternative to traditional pigments, such as those based on iron oxide and titanium dioxide which cannot be used for the preparation of metal free leathers, and which allows to correctly reproduce the spectral curve of a large number of colours.
The company ensures that before sale each lot is subjected to numerous checks to ensure the consistency of the declared features. Moreover, the absence of banned substances is verified by GSC through tests and analysis of production batches.
The abatement of volatile organic compounds emissions (VOCs) in leather products intended for interior car upholstery destined for the automotive sector, is another research field that has seen GSC Group at the forefront for years. With the aim of maintaining the quality and resistance required by car manufacturers, GSC Group’s proposal aims to be a solution able to predict lower emissions of non-hazardous compounds while also improving their performance features. In the finishing phase, GSC Group has managed to optimise the application of the topcoat by bringing emissions below 1% with very good results in both light and dark colours.
The R&D staff also developed a new 100% solid isocyanate-based opaque cross-linker (CRX A 100), designed to replace current NCO cross-linkers in all finishing products.
