VOC-FREE NEUTRALIZING AGENT

Clariant claims to break new ground for the indoor paint and coatings segment with the launch of what it says is the industry’s first renewable-based, VOC/SVOC-free1 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. 
Genamin Gluco 50 combines its sustainable profile with performance-boosting properties to 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. 
It 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).

The product 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 deg. C for 28 days. The lacquer also remains stable after five freeze-thaw cycles.
It offers increased tinting strength thanks to better pigment compatibility. Waterborne paints and pigment dispersions neutralized with Genamin Gluco 50 show higher tinting strength.
Enhances metal protection due to reduced flash rust formation. It also helps to protect the coating film against discoloration caused by rusting.
It is VOC/SVOC free and reportedly has a pleasant smell. It also helps to make paints and coatings easy to apply. The company says it has no negative influence on paint properties, such as gloss or on drying or hardness behavior.
