The Leather Casein Additive EXPERT LINE additive in coating compositions by LeTech.
Casein belongs to the classical film formers of the protein type in the classification of leather coatings. It comes from milk, in which it is found in the form of calcium caseinate.Casein paints have a disadvantage in terms of resistance to water, which is the reason why casein is so poorly used today.
However, modified casein solutions are permanent components of coating paints for finishing of shoe leathers and other leathers, where high hygienic properties and breathability are required.
The modified casein film formers of the EXPERT LINE series make it possible to obtain coating films that have all the positive characteristics of the original casein paint described above. At the same time, the strength and moisture resistance of the coating meet the highest requirements.
The undisputed advantages of casein-based top coatings for leather include: elasticity, durability, high durability, and stability of application characteristics.
The Leather Casein Additive additive in the coating compositions gives the leather valuable properties, such as:
- High aesthetic appeal;
- Resistance of the coating to water and aggressive media;
- Resistant to mechanical abrasion and other influences;
- Creation of dispersion film, which increases vapour and moisture exchange.
The Leather Casein Additive EXPERT LINE finishing additive is ideal for:
- Leather clothing & footwear
- Leather accessories
