Experience, reliability, innovation - Deffner & Johann celebrates 140 anniversary

Dear customers

We would have very much enjoyed celebrating our anniversary with you at denkmal 2020, because 140 years would have been a great occasion. As you know, things turned out differently and all trade fairs and conferences had to be cancelled. We would therefore be happy to present some of the things we would have liked to show you in Leipzig: a selection of the latest innovations, D&J infographics, as well as the familiar and the tried-and-tested.

We appreciate your interest and will be happy to answer any questions you may have.

Your Ralph-Uwe Johann & Team

New in stock - MS3, an Australien Innovation

The new MS3 is the successor to MS2A and was developed by CSIRO (Commonwealth Scientific and Industrial Research Organization) in collaboration with leading museums in Australia and Europe. Carl Villis, Senior Conservator of Paintings at the National Gallery of Victoria (NGV) comments: "MS3 is clearer and more consistent in its appearance than the earlier resin as a direct result of the flow chemistry process employed by CSIRO's scientists."

Visit Gamblin in Portland

On site in Portland

This summer Deffner & Johann had the wonderful opportunity to visit Robert Gamblin and his wife Catherine in Portland, USA. On a beautiful sunny morning Robert led us through his paint factory, showed and explained the production of the paints - it was "Red Day".

Gamblin's company produces more than 200 colors in an environmentally friendly and safe production process in southeast Portland. Gamblin Artists Colors' paints and Gamsol solvent - an odorless solvent - are all non-toxic and lead-free.
