EMDİRENAL RTD has a wide range of applications in the retannage of all types of chrome leather and in the vegetable tannage.

The product improves the tightness and the fineness of the grain, gives firmer and fuller handle. Buffing and embossing properties are particularly improved by retannage with EMDİRENAL RTD. It improves the nap of suede leather. Thickness will be improved especially in the flanks and looser parts.

EMDİRENAL RTD 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 slight buffering property. Unlike other resin tanning materials EMDİRENAL RTD 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 and finer grain structure along with good fullness is obtained.

EMDİRENAL RTD also improves the take-up of the grain impregnation agents and provides better finishing results. We strongly recommend its use for all types of aniline leather.
