Bio-based adhesives & cleaners
Environmental thinking - not waiting!
The world’s population is increasing - but our fossil resources are decreasing. So, more than ever before, it is essential to think of a sustainable future! Exactly for these reasons, sustainability, particularly regarding environmental protection, is of particular importance. It is therefore also an important subject for Weiss, not only for today, but also for future generations.
Responsible management of our water protection, exhaust gasses, and waste cyclesalready form part of our firmly established standards. And now, to further optimize our utilization of resources, we are concentrating on replacing fossil fuels in our adhesives with renewable resources.
Ecological sustainability - bio-based adhesives
Our bio-based adhesives actively contribute to the protection of the environment: As innovative products, they have been developed with particular consideration for our limited resources, yet without losing sight of the top quality which we consider a matter of course.
To a large extent, many of these raw materials produced by agricultural and silvicultural processesare climate-neutral. This way, no increase of CO² emissions will be generated in the future. Environmental and limited resources will be protected for further generations. In the meantime, there are numerous possibilities for processing the most diverse bio-based materials such as starch, vegetable oil, resins, lignins, proteins, and others. It is also possible to use renewable raw materials in adhesives. By substituting fossil resources, we have succeeded in developing adhesives on the basis of bio-based products.
Optimization of our adhesives
Our bio-based adhesives include a high content of raw material from renewable sources. Simultaneously we are further improving their already very good properties. Sustainable quality....made by Weiss!
COSMO® PU-200.910
Biobased 2-part PUR adhesive
