Rockbiocide LP-30 – Fungicide and Antibacterial Agent for Wet Blue Leather Protection

Rockbiocide LP-30 is a low-toxicity fungicide specially developed to protect wet blue leather against mould, mildew, and fungal attack during storage and transportation.

Based on TCMTB (2-Thiocyanatomethylthiobenzothiazole) technology, it provides reliable and long-lasting protection, helping leather manufacturers preserve the quality and appearance of wet blue leather.

Rockbiocide LP-30 is free from pentachlorophenol (PCP) and phenol derivatives, making it a safer and more environmentally responsible solution for modern leather processing. The product is particularly suitable for pickling and chrome tanning operations where effective fungal control is essential.

Technical Specifications

Applications in Leather Processing

Rockbiocide LP-30 is specifically formulated to prevent mould and fungal growth in wet blue leather during processing, storage, and shipment. The product provides effective protection by inhibiting microbial activity that can cause staining, odor, and leather deterioration.

Recommended applications:

For optimum performance, Rockbiocide LP-30 should be prepared as a dispersion immediately before use to ensure uniform distribution throughout the leather.

Recommended Dosage

Pickling

• Up to 0.1% based on pickled weight.
• Add before acid addition.

Chrome Tanning (Wet Blue)

• 0.1–0.3% based on pickled weight.
• Add at the end of the chrome tanning process.

For long-term preservation and storage under humid conditions, higher dosages may be required along with uniform surface spraying.

Application Guidelines

To achieve the best antifungal performance:

• Prepare the product dispersion immediately before use.
• Ensure uniform distribution throughout the processing bath.
• Apply additional surface spraying for extended storage periods.
• Test the product under your own production conditions before large-scale use.

Because leather types, degreasing methods, and processing conditions vary from tannery to tannery, laboratory and production trials are recommended.
