Acrytan SN

Primary Uses

Leather Tanning & Retanning
- Used as a synthetic tanning agent (syntan) to improve leather softness and uniformity.
- Enhances fiber dispersion, making leather more flexible and less prone to cracking.
- Often combined with vegetable or chrome tanning for balanced properties.
Lightfast & White Leather Production
- Ideal for white and pastel-colored leathers (e.g., fashion accessories, upholstery) due to its resistance to yellowing.
- Used in automotive leather, footwear, and luxury goods.
Fatliquoring & Softening
- Helps retain natural oils in leather, improving suppleness.

Secondary Uses

Leather Finishing
- Used in top coatings to enhance smoothness and durability.
Textile & Non-Woven Fabric Treatment
- Occasionally applied to synthetic leather (PU/PVC) for better hand feel.
Paper & Packaging Industry
- Used in leather-like paper coatings for premium packaging.

SAFETY HANDLING

Safety Precautions

Personal Protective Equipment (PPE)

Gloves: Nitrile or neoprene (chemical-resistant)
Eye Protection: Safety goggles (for liquid/splash risk) or face shield (if handling powder)
Respiratory Protection:
- N95 mask (for dust/powder)
- Organic vapor respirator (if handling solvent-based formulations)
Clothing: Lab coat or chemical-resistant apron

Handling & Storage

Work in a well-ventilated area (use a fume hood if handling solvents).
Avoid skin/eye contact—acrylic compounds can be irritants.
Store in a cool, dry place away from direct sunlight and heat sources.
Keep away from strong oxidizers (e.g., peroxides, chlorates).
Ground containers to prevent static buildup (if flammable solvents are present).
