Resistance to chemicals
Competence: Our expertise for your success
Established in Germany 100 years ago, we meet the highest standards in quality and sustainability worldwide. Our technical application-related knowledge ensures excellent results for our customers’ projects.
LOBA products are continuously tested by our Application Technology and R&D teams to ensure consistent quality and develop our products further on the basis of new requirements from our customers and legal requirements.
The tests are very extensive and include the following:
Ease of processing
Resistance to roller marks
Sandability (intermediate sanding)
The right product for every project:
Sustainability requirements and stress level
What are the sustainability requirements of the project?
The sustainability data sheets give you an overview of the sustainability aspects of a product. You will get a deeper insight into the sustainability seal of approval here.
What level of stress will the floor be subjected to?
The LOBA stress levels help you to choose the right product. We have defined the stress level of our varnishes using a clear calculation method. We use 4 test categories that best represent the resistance of the varnishes:
Resistance to chemicals
Based on laboratory values in the various categories, the 1K and 2K varnishes are rated on a scale of 1-10 and an average value is calculated.
The 4 test categories in detail
First, the sample is scratched by applying an increasing weight force and then the visual result is assessed in a light chamber according to precisely defined criteria.
The higher the weight force required, the more resistant the sample is to major scratches.
In this case, a stress test is performed only on the varnish without primer.
The sample is subjected to an abrasion test involving a total of 1,000 cycles. The weight of the sample is then compared before and after in order to determine the exact abrasion value.
The lower the abrasion value, i.e. the weightloss, the higher the resistance of the surface to wear.
In this case, a stress test is performed on the overall finish with primer.
The “CS-17 Falling Sand” method involves subjecting the sample to a highly abrasive test until the wood surface is worn through and all coats of varnish are completely removed.
The higher the number of cycles required for wearing through the finish, the higher the resistance and durability of the overall finish.
16 chemicals are applied to the samples and then removed after a certain exposure time (24 hours for almost all chemicals). After a regeneration time of one day, a visual assessment of the varnished surface is performed according to precisely defined criteria and evaluated based on a point system.
- Red wine
- Sodium carbonate
- Acetic acid
- Citric acid
- LOBA CareRemover
- Paraffin oil
- Olive oil
- Ethanol 48% (spirits)
- Ethanol 96% (disinfectant)
- Chloramine T (disinfectant)
- Acetone (contained in nail polish remover)
- Butyl acetate (strong solvent)
The higher the score, the more resistant the surface is to chemicals.
We want to share our technical competence with our business partners by providing them with training workshops and practical seminars so that they can make the best possible use of LOBA products and achieve excellent results.
