Emdirenal RTW produces extremely white, tight and fine grained leathers with a mild, full handle. The leathers treated with show very little tendency to yellow under conditions of light and heat.
When included in the vegetable tannage Emdirenal RTW accelerates tanning material penetration, improves grain properties, lightens the leather color and levels out dyeing. Emdirenal RTW reduces the astringent effect of the more heavily filling vegetable and synthetic tanning materials, thus reduces the risk of grain cracking. Due to its low astringency finer grain structure along with good fullness is obtained.
Emdirenal RTW has very low astringency, therefore part of the retanning with Emdirenal RTW can be given before neutralization, giving a pronounced improvement in whiteness.
Emdirenal RTW is fully compatible with anionic tanning materials, acid dyes and other anionic leather auxiliaries. Its addition accelerates tanning material penetration, it evens the difference of acidities of other products, thanks to its good buffering property. Due to its very good dispersing action vegetable and resin tanning materials that are included penetrate deeper and more uniformly.
When combined with resin tanning material like Emdirenal RTD, Emdirenal RTU, Resingan DK-66 better buffing and embossing properties with excellent finishing results are obtained.
