Bio-based polymers

 
There is a growing awareness of the environmental impact of our behavior on the future of our planet. In the paint market, the first generations of polymers taking into account this awareness were water-based, formaldehyde free, and with low VOC. In the 2010s emerged a new generation adding bio-based component using renewable resources up to 99%. Improvement on C02 emission were significant (source BEGES/ Bilan Carbone cradle to gate): Solvent born polymers (3,2 Teq CO2/T), Water based Polymers (2.O Teq CO2/T),bio-based polymers (1,3Teq CO2/T), bio-based carbon chain (-1,4Teq CO2/T), (negative due to the vegetable carbon stemming for the atmospheric CO2). Using bio-based polymer has a neutral impact in term of C02. But the consumer and regulatory demand are always pulling innovation. Technologies adding functionalities improving health were launched. Indeed Formaldehydes are identified to be the most dangerous pollutant in interior air. Many governments, like France, are stringing their regulation to reduce this content in public building. 3- Latest technology evolution. The latest polymer launched by Ecoat (the SECOIA 1437) combines biobased origin up to 94% with formaldehyde scavenging: low Carbon footprint and positive impact on interior air quality. This polymer provides the application behavior (open time) and film quality of a water based alkyd but with the color hold and drying time of an acrylic. This polyester targeted for interior applications can be used from mate to glossy wall and ceiling paints as well as for door lacquers and varnishes.
