Rockapon WTO – Powerful Wetting and Soaking Agent for Leather Processing

High-Performance Wetting Agent for Soaking Hides and Skins

Rockapon WTO is a highly effective anionic wetting and soaking agent specially developed for the leather industry. Thanks to its excellent penetrating power and outstanding solubility, it accelerates water absorption and ensures uniform soaking of hides and skins.

Based on sulphited alcohol technology, Rockapon WTO performs efficiently in acidic, neutral, and mildly alkaline media, as well as in hard water conditions. It is particularly recommended for soaking wet-salted, dry-salted, and dried hides and skins, helping tanneries achieve cleaner, softer, and more uniformly hydrated pelts.

Why Choose Rockapon WTO?

The soaking stage is one of the most important operations in leather processing. Proper soaking restores the moisture content of raw hides and skins, removes impurities, and prepares the material for subsequent beamhouse processes.

Rockapon WTO has been formulated to maximize wetting efficiency and improve process performance.

• Effective in acidic, neutral, and mildly alkaline media.
• Performs efficiently in hard water conditions.
• Improves rehydration of hides and skins.
• Promotes uniform soaking results.
• Helps remove dirt, blood, and soluble impurities.
• Suitable for wet-salted, dry-salted, and dried raw stock.
• Compatible with conventional soaking systems.

How Rockapon WTO Works?

Rockapon WTO reduces the surface tension of water, allowing it to penetrate quickly and evenly into the hide structure. Its strong wetting action ensures efficient rehydration and improves the effectiveness of subsequent beamhouse chemicals.

During soaking, the product helps:

• Accelerate water penetration.
• Restore the natural moisture content of hides and skins.
• Remove dirt and soluble proteins.
• Improve fiber opening.
• Enhance the performance of liming and enzymatic treatments.
• Produce cleaner and more uniform pelts.

Applications:

Rockapon WTO is recommended for:

• Soaking wet-salted hides and skins.
• Soaking dry-salted hides and skins.
• Processing dried hides and skins.
• Beamhouse operations.
• Leather preparation before liming.
• Bovine leather processing.
• Sheep and goat skin processing.
• Industrial soaking systems.

Ideal for Different Types of Raw Materials

Rockapon WTO provides excellent performance in the treatment of:

• Wet-salted hides.
• Dry-salted hides.
• Dried skins.

• Goat skins.

Its powerful wetting properties ensure rapid and uniform soaking even for difficult-to-process raw materials.

Technical Specifications

Recommended Dosage:

Wet-Salted Hides and Skins

• 0.5–1.0% based on hide or skin weight.

Dry-Salted and Dried Hides and Skins

• 1.0–2.0% based on hide or skin weight.

The optimum dosage depends on the condition of the raw material, storage time, and process requirements.

For improved hygiene and preservation during soaking, the use of antibacterial products such as Negahdar IST-WB is recommended.
