Genagen® COA
VOC-free coalescing agent for emulsion paints
Genagen COA is a non-VOC coalescing agent for decorative coatings.
Many additives contain volatile organic compounds (VOC) that evaporate and degrade the environment, which are harmful for humans. Genagen COA complements paint formulator’s attempts to replace VOC-containing coalescing agents, and effectively reduces minimal film formation temperature (MFFT) of paint binders based on styrene/acrylic monomers, pure acrylic emulsion polymers and vinyl acetate polymers. It strongly supports the film formation at lower temperatures with little impact on the paint viscosity and binders. Genagen® COA can be added to the binder and the paint and is recommended to be used in low PVC paints like facades paints, wood coatings and lacquers. Dosage: 1 – 4%product on polymer binder.

Most common coalescing agents have a boiling point below 250 °C and are classified as VOCs. These substances evaporate and are harmful for humans and the environment. Examples are methoxy propylene glycol ethers and ester alcohols. Genagen COA is based on an oleochemical with a boiling point above 250 °C and the carbon content is in parts naturally derived. Moreover, if released to the environment accidently, it is biodegradable and does not contain any biocides.
