As an internationally operating specialist dealer for materials, tools and equipment for restoration, conservation, archiving, depot and transport, Deffner & Johann had set itself the goal of presenting visitors to the tenth Exponatec Cologne, not only a representative overview of proven and new products from its product range, but also a platform for exchange.
We are pleased that we can once again offer our customers Cyclododecane for their applications in restoration, monument conservation and archaeology.
On the occasion of the 80th birthday of the long-time owner and managing director, Deffner & Johann is launching an exceptional brush series: "Meisterklasse Edition Harald Johann".
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
Gunnar Ottosson produces sustainable linseed oil paints in an extremely environmentally friendly way at his Färgmakeri factory in Sweden.
Linseed oil has been a proven and versatile binder in heritage conservation and restoration. Its environmental compatibility and resource-saving production have made it an increasingly popular paint system in modern, innovative architecture.
Please read the following interview with Gunnar Ottosson - Author: Susanne Sachsenmaier-Wahl; published in the German-language magazine Malerblatt.
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."

Dear customers, dear customers,
As Managing Director of Deffner & Johann, it is important to me to address you personally today.
Deffner & Johann is celebrating its 140th anniversary. Due to the Corona crisis, the anniversary is under very special circumstances. Customer events and trade fair visits have been paused. COVID-19 presents us all with enormous challenges. Especially now it is important to keep the principles of the last decades in focus: To act reliably for customers, employees and suppliers.
As a company, we have taken numerous measures since March 16 to adapt our processes to the changed situation and to take the best possible precautions for the health of my employees.
Together with SHAKEINCONSERVATION SHAKEINCONSERVATION, a non-profit organization to connect students and young professionals in conservation in Belgium, Deffner & Johann hosted a two day workshop on soft particle cleaning at the University of Antwerp.
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.
