Bentone 34

Buyers should prioritize the chemical composition (tetraallkyl ammonium bentonite) and physical properties. Key metrics include moisture content (typically <3.5%), loss on ignition (28%-32%), and fineness (95% passing through 200 mesh). Ensure the product offers consistent viscosity increase and sag resistance for solvent-based systems like paints, coatings, and lubricating greases.

Bentone 34 is a versatile rheological additive designed for low to medium polarity organic liquids. It is highly effective in industrial decorative paints, wood stains, printing inks, and heavy-duty anticorrosion coatings. It is also a critical component in manufacturing high-temperature lubricating greases due to its excellent thermal stability and thickening efficiency.

Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For specific markets, verify REACH registration (EU) or TSCA inventory status (USA). Since it is a chemical powder, ensure the packaging meets UN-certified standards to prevent moisture absorption and leakage during maritime transit.

Request a pre-shipment sample (typically 500g) to conduct a dispersion test in your specific solvent system. High-quality Bentone 34 should require high-shear mixing and a polar activator (such as methanol/water 95/5 or propylene carbonate) to reach full efficiency. Compare the gel strength and transparency against a benchmark sample.

The main risks include moisture contamination during sea freight and batch-to-batch inconsistency. To mitigate this, insist on vacuum-sealed multi-layer paper bags with PE liners. Use Made-in-China.com's Secured Trading services to ensure payment is only released after a third-party inspection (like SGS) confirms the Certificate of Analysis (COA) matches the delivered goods.

Standard MOQs for organoclays are usually 500kg to 1 ton (one pallet). For bulk orders exceeding 5 tons, you can typically negotiate a 10-15% discount. Discuss Incoterms 2020 clearly; while FOB is common, CIF may be more convenient for buyers unfamiliar with chemical logistics, as the supplier handles the complex dangerous goods (if applicable) or sensitive cargo documentation.

Bentone 34 is sensitive to humidity. Ensure the container is dry and clean, and request the use of desiccant bags inside the container. Verify that the supplier provides a Non-Dangerous Goods Certificate (if the specific grade allows) to simplify customs clearance and reduce freight costs compared to hazardous material handling.

Always verify the supplier's Business License and Export Qualification. On Made-in-China.com, look for Audited Suppliers who have undergone on-site inspections. Utilize Escrow payment terms or Letters of Credit (L/C) for large-scale industrial orders to protect your capital against non-delivery or sub-standard product quality.
