Coatex Arkema
This is a Past Webinar

Is formulating low to zero VOC coatings while keeping a high level of performance in your focus today? We may have a solution for you!

Coatex has designed COADIS™ 123K, an hydrophobic dispersant, to address the regulation challenges concerning the formulation of low to zero VOC coatings. COADIS™ 123K helps to improve water resistance and thus other coating properties.

To learn more about this technology and its attractive features, access the video recording of the presentation made by Coatex at ECS 2015 (Nuremberg - April 2015)!

Presented By:
Denis Ruhlmann

Length: 20 min

Why should you view this webinar?
