The new OPTITAN-Range consists of carefully selected products, which belong to a new generation of syntans, designed for optimized application results. These products are highly concentrated and low in salt content.
Due to the resulting products’ effectiveness, they enable a reduction in application dosage (%) and costs of effluent treatment, transport and inventory.
The OPTITAN-Range group of retanning agents fulfil new requirements and are low in free-formaldehyde and free-phenol, they enable the production of leathers with low emissions. All products also offer a good fastness profile. Some products are completely new to our range, others are thoroughly optimized and renewed to meet those requirements.
The SmiTool Light and Heat already discussed the subject of heat yellowing and light fastness tests on leather. The current SmiTool explains the differences between subjective and objective assessments of tested leather and how to report test results for heat yellowing and light fastness.
Learn about the important aspects when making tight leather, the influence of post-tanning processes and which Smit & zoon products are most suitable for your optimal leather properties.
Learn about the many different parameters that influence good, waterproof leather. Making leather waterproof contains more than just choosing the right fatliquor (this is actually the easiest part). The key lies in the right processes such as running times, temperature control, washing and polyvalent metal fixing.
