Whether you call it the B component, accelerator, cross-linker, or simply hardener: the fact is that the »OLI-NATURA HS Hardener« is 0% VOC, emission-free, and can be applied without mandatory training. But what are we actually talking about here?
As of August 24, 2023 a training requirement comes into force for conventional hardeners with an increased diisocyanate content. Anyone working with hardeners containing more than 0.1 percent diisocyanates must undergo training. This regulation is based on EU Regulation 2020/1149 restricting diisocyanates, which have been classified as potentially harmful from an occupational, environmental, and consumer protection perspective.
NO TRAINING REQUIRED
We give the green light: Our »OLI-NATURA HS Hardener« has been ahead of its time since 2018 and is state of the art. Anyone who works with this additive does not need to attend training. The reason is that our »OLI-NATURA HS Hardener« which is well below the EU limit values. This also means that no training is required, which which, incidentally, applies to all our hardeners. But aOur product also impresses in terms of environmental friendliness »OLI-NATURA HS Hardener«. This hardener is VOC-FREE, meaning it contains no volatile organic compounds and is therefore emission-free.
THE NETWORK MAKES THE DIFFERENCE
Anyone who uses the »OLI-NATURA HS Hardener« with OLI-NATURA 2K oils creates oiled surfaces with very high chemical resistance and accelerates drying. This means that adding the hardener significantly shortens the curing reaction of the oxidatively drying oil because it initiates an additional cross-linking reaction of the oil molecules. The duo forms particularly dense oil structures that are firmly anchored in the wood and highly resistant. The beneficial basic properties of the oil-based surfaces are retained.
SAVES TIME
The name itself gives it away: »OLI-NATURA HS Hardener« increases the final hardness and shortens the drying and curing time. This is particularly beneficial when time is an important factor: for example, to minimize the downtime of freshly oiled wooden floors in schools and hotels or to save production time and storage capacity. Furniture surfaces such as wooden tabletops or washbasins that are exposed to heavy daily use can also be protected very effectively with 2K oils. When the hardener is added to the »OLI-NATURA Colour-Oils« and »OLI-NATURA HS Professional Oils« also results in a more intense colouration.
QUICKER AND DARKER

Especially for the »OLI-NATURA Colour-Oils« and above all the MIDNIGHT-BLACK« work very well with the »OLI-NATURA HS Hardener«. Adding the hardener component further enhances and optimally fixes the colour. That is why we are working intensively on concepts that »OLI-NATURA Colour-Oils« to offer in the future as a 2K version. At the same time, we will continue to develop products such as »OLI-NATURA Scandic-Oil« to offer optionally as a 2K product and meet the wishes of raw wood effect enthusiasts. However, this will not become an issue until the new product year begins in April 2023 at the earliest.

WHAT SHOULD BE OBSERVED DURING APPLICATION
Although this hardener is not classified as dangerous goods, standard protective measures such as wearing gloves should be observed. Here are a few tips:
- Process HS Hardener at room temperature and shake well before use!
- Mix HS Hardener thoroughly with the oil in the specified ratio shortly before use.
- Process the oil-hardener mixture immediately and do not pour excess material back.
- Regular stirring stabilizes the viscosity of the mixture.
- Observe pot life (processing period)
