The word "eco" often raises a certain scepticism in the industrial world. "Will it be just as strong?", "Won't it dissolve in the sun?", "It's probably harder to work with?". Time to dispel these myths. Thanks to the technology from Resoltech, which we are bringing into our range, "eco" today simply means "designed smarter".
Most conventional resins are made 100% from crude oil. Bio-based resins change these proportions — replacing some of the petrochemical ingredients with renewable raw materials (per the ASTM D6866 classification). Instead of drawing solely on fossil fuels, some of the carbon atoms are obtained from renewable plant sources.
Oil plants: sunflower, rapeseed, cashew nuts.
Drzewa: np. sosny (pozyskiwanie kalafonii i pochodnych).
Produkty uboczne: e.g. vegetable glycerine.
Importantly, you don't have to take our word for it. The "bio" content is measured by the precise carbon-14 isotope dating method. This makes it possible to distinguish "young" plant carbon from "old" carbon from crude oil, which is millions of years old.
This is the most important point: bio-based products do not have inferior mechanical properties to their conventional counterparts. In many cases they are even better.
The manufacturer, Resoltech, with over 30 years of experience, points to specific improvements in the ECO versions:
1020 ECO: Better thermomechanical properties after cure compared with the standard version.
1070 ECO: Higher UV stability and better strength.
1010 ECO: Improved abrasion resistance and surface hydrophobicity.
By choosing a glycerine-based resin instead of an oil-based (propylene) one, you genuinely reduce the burden on the environment. Look at these comparative figures for the production process:

| Parameter | Redukcja o… |
| Global warming impact | 83% mniej |
| Niszczenie warstwy ozonowej | 78% mniej |
| Environmental acidification | 36% mniej |

Even if the finished resin product (which is thermoset and irreversible) is one day disposed of by incineration, the carbon balance is much better – the plant from which the resin was made previously took that carbon from the atmosphere.
Bio-based resins are not theory – they are already working in the toughest conditions:
Sport: Surfboards (1070 ECO resin + flax).
Budownictwo: A 70-metre bio-composite bridge in the Netherlands (1800 ECO system).
Marine: Yacht building and marine structures (leading luxury yacht builders)
Motorsport: Body parts, structural components, etc.
Sztuka: River tables, deep castings, furniture, etc.
Switching to ECO systems is not just a matter of image. It is access to modern formulations that offer the same, and often higher, durability and ease of application (laminating, infusion, casting), while drastically reducing the carbon footprint.
As a distributor of Resoltech solutions, we help you choose the right ECO system for the specific needs of your production.
