Products for Water Repellent Leathers



TECHNICAL ASPECTS



Our range of water repellent products can be used for footwear, both on the grain and the split, furniture, especially with anti-stain behavior, and soft clothing. All of the products used to make water-repellent leathers are specific; it is therefore necessary to avoid all hygroscopic products that could weaken the system. A fatliquor plays the main function of softener and hydrophobizer, covering the fibers and isolating them from the water. Other specific auxiliaries and retanners are used like normal products to obtain all the desired characteristics.



IDROPOL P-24


IDROPOL P-24 is a silicone emulsion in water for use in drum. Its composition makes leather water-repellent because of an effective fiber coating as well as a filling of the inter fibrillary spaces. This creates a closed and well sealed system. It is a fatliquor of medium softness and gives a very firm grain. It is also suitable for nubuck and splits where it gives uniform and bright dyes.

REFIL V-30


REFIL V-30 is an acrylic resin specific for hydro and nubuck footwear. It gives a good filling of the sides and when used in the splits increases the closure of the fibers. It sands well and keeps high the water repellent action of the hydrophobic leather.

MAX A


MAX A is an auxiliary for normal and water-repellent leathers. It disperses the fatliquors, the anionic retanning agents and the dyes allowing an optimal crossing of the section and a better uniformity throughout the surface. It sands well and being esterified, helps to maintain a water-repellent effect.




The dyeing phase of hydro articles may present some problems for workers due to the fact that it is preferable to avoid penetrating naphthalene tannins or other dispersants. To obtain uniform dyes, we recommend the use of esterifying dyeing auxiliaries.

On the other hand, the washable items present a critical issue regarding dye-bleeding during washing cycles in the washing machine. In addition to adopting a dedicated retanning process, special dyes are needed which resist these treatments.
