Switzerland-based Clariant, a world leader in specialty chemicals, breaks new ground for the indoor paint and coatings segment with the launch of the industry’s first renewable-based, VOC/SVOC-free (volatile organic compounds and semivolatile organic compounds) and hazard label-free neutralizing agent: Genamin Gluco 50. The new sugar-based additive innovation supports formulators in meeting consumer demand for low odor, healthier and easy to apply indoor paints and lacquers. Its introduction is also significant for ecolabel certified paints, where a reduction in additives can help to keep a formulation within low VOC/SVOC limits.
According to the Swiss chemical giant, “Genamin Gluco 50 combines an outstanding sustainable profile with performance-boosting properties that set it apart from existing neutralizing options for waterborne coatings. In contrast to standard neutralizers, such as ammonia or caustic soda, Genamin Gluco 50 does more than adjust the pH-value of a formulation to around 8-10 to create a stable paint system with minor interactions between the paint. It also enhances the performance and quality profile of the waterborne coating”.
Genamin Gluco 50 acts as a 3-in-1 additive, being neutralizer, compatibilizer and stabilizer in one additive. The product achieves additional functionalities and proven advantages for the formulation, such as improving storage stability and pigment compatibility, and reducing flash-rust formation. In certain aspects, its performance is proven to be superior to that of alternative multifunctional additives such as aminomethyl propanol (AMP), currently under scrutiny and substance evaluation by the ECHA (European Chemicals Agency).
“Genamin Gluco 50 – Clariant claims – offers the following extensive benefits: improves paint lifetime and storage stability even in colder regions. Gloss lacquers containing Genamin Gluco 50 show no syneresis, sedimentation or changes to pH-value or viscosity after storage at 50°C for 28 days. The lacquer also remains stable after 5 freeze-thaw cycles. It increases tinting strength thanks to better pigment compatibility. Waterborne paints and pigment dispersions neutralized with Genamin Gluco 50 show higher tinting strength. It enhances metal protection due to reduced flash rust formation. It also helps to protect the coating film against discoloration caused by rusting. Genamin Gluco 50 is VOC/SVOC free and has a pleasant smell. It also helps to make paints and coatings easy to apply. It has no negative influence on paint properties, such as gloss or on drying or hardness behavior”.
“Achieving multifunctionality from a single VOC-free additive – Alexander Snell, Head of Sales Industrial Applications EMEA, Clariant Business Unit Industrial & Consumer Specialties, comments – overcomes a major challenge for paint formulators faced, in particular, with the low VOC/SVOC limits of the ecolabels such as the German Blue Angel. Genamin Gluco 50 is the ideal component for the paints of today and tomorrow. It helps paint formulators to replace ingredients that are under scrutiny, offering a package of high performance and eco-related benefits that satisfy paint manufacturers, professional painters and consumers.”
