D68 Matting Hardener
The D68 Matting Hardener is a polyamine-based curing agent formulated for use in epoxy and polyester hybrid powder coatings. It is chemically equivalent to Huls B68, offering comparable crosslink density and surface finish characteristics. The product appears as a pale yellow to off-white granular solid with a melting point between 85°C and 95°C, suitable for industrial powder application processes.
It is designed to achieve controlled matte finishes without requiring additional matting agents, reducing formulation complexity. The hardener exhibits low viscosity when molten, allowing for smooth flow and even film formation. Typical loading levels range from 4% to 8% by weight in powder systems, depending on the desired gloss level and resin type. It demonstrates good storage stability under dry conditions below 30°C.
This product is primarily used by manufacturers of architectural coatings, automotive refinish systems, and industrial machinery finishes. Buyers include powder coating formulators, OEMs in the appliance sector, and contract finishers. Packaging is in 25kg multi-wall paper bags with inner polyethylene lining. Trade terms are typically FOB Ningbo, with lead times of 15 to 20 days after order confirmation. Buyers should confirm compatibility with their specific resin system before scale-up.

Sourcing D68 Matting Hardener from Ningbo Zhihua Chemical Co., Ltd. - China Import Guide
Before ordering, confirm the chemical equivalence to Huls B68 with a Certificate of Analysis including amine value, moisture content, and particle size. Request a sample batch to test compatibility with your resin system and verify the finish quality under your standard cure cycle. Ensure the supplier provides a safety data sheet compliant with GHS standards.
Lead time is typically 15 to 20 days after order confirmation, with FOB Ningbo as the default term. Payment is often 50% advance, 50% against shipping documents. Buyers should clarify if the supplier handles export permits for chemical products and whether the packaging meets IATA/IMDG regulations for transport of organic solids.
For quality assurance, inspect each batch for color consistency, absence of lumps, and dryness. Request a batch-specific test report for melting point, moisture content, and residue on ignition. Retain samples for retesting after storage. Confirm that each bag is labeled with batch number, date of manufacture, and handling instructions.
