About Ningbo Kaaki Co., Ltd - Chemicals & Allied Products Supplier in China

Ningbo Kaaki Co., Ltd is based in China and currently lists five active chemical products. The catalogue falls under the Chemicals & Allied Products category and includes two alkyd resin variants, a waterborne UV‑curing polyurethane acrylate dispersion, and two polyester diols. The water‑soluble alkyd resin is recorded with HS code 3905.90 and described as a water‑soluble acrylic‑modified short‑oil alkyd resin. The UV‑curing polyurethane (PUA) resin carries HS code 3909.50 and is a plant‑oil modified aromatic polyurethane acrylate dispersion. The linear polyester diol (PBA 1000) is listed under HS code 3907.99 as a linear polyester diol, while the long‑oil self‑drying alkyd resin and PEA 1000 elasticity polyester diol are listed without specific HS codes.

The long‑oil self‑drying water‑soluble alkyd resin is formulated for coating applications that require rapid film formation and water‑based processing. The PEA 1000 elasticity polyester diol is intended as a soft‑segment component in polyurethane formulations, providing flexibility and elongation. The water‑soluble alkyl resin series is used as binders in architectural and industrial paints, offering low VOC emissions. The UV‑curing PUA dispersion enables fast curing under UV light, commonly employed in wood finishes and graphic coatings. The linear polyester diol serves as a chain extender in thermoplastic polyurethanes, delivering specific hydroxyl numbers and molecular weights.

Product Range and Specialties of Ningbo Kaaki Co., Ltd

The product range includes water‑soluble alkyd resins, both short‑oil (acetylated) and long‑oil variants, which are typically characterized by solids content of 45‑55 wt %, viscosity between 500 and 2000 cP at 25 °C, and acid values ranging from 30 to 70 mg KOH g⁻¹. The UV‑curing polyurethane acrylate (PUA) dispersion is usually supplied with solids percentages of 30‑60 wt % and viscosities of 1000‑5000 cP, formulated to achieve full cure within seconds under 365 nm UV lamps. Linear polyester diols such as PBA 1000 are specified by hydroxyl numbers of 40‑100 mg KOH g⁻¹ and molecular weights between 1000 and 2000 Da, making them suitable for flexible polyurethane synthesis.

Typical industry grades for these chemicals adhere to ISO 9001 quality‑management standards and often require REACH registration for European markets. Buyers also look for compliance with RoHS when the resins are destined for electronic or automotive coatings. Standard test methods include ASTM D1238 for melt flow, ASTM D1475 for viscosity, and ISO 16212 for UV‑curing performance. Packaging is generally in 200‑L steel drums for bulk shipments or 25‑kg IBCs for smaller orders.

Trade and Export Information - Ningbo Kaaki Co., Ltd

China is a leading exporter of specialty resins, with Southeast Asia, Europe and North America representing the largest import markets for water‑based alkyds and polyurethane dispersions. The HS‑code families 3905, 3907 and 3909 are routinely inspected by customs for compliance with safety data sheet (SDS) requirements and may trigger REACH or TSCA notifications depending on the destination. Exporters typically provide ISO 9001 certificates, REACH registration numbers, and third‑party analysis reports to satisfy buyer due‑diligence.

Logistically, bulk resin shipments are loaded in 20‑ft or 40‑ft containers, each container holding up to 15 tons of 200‑L drums, and are commonly shipped under FOB Ningbo or CIF terms to major ports such as Rotterdam, Los Angeles and Singapore. Standard packaging includes metal drums sealed with tamper‑evident caps and placed on Euro pallets to facilitate handling. Buyers should verify that the declared HS code matches the material description and request a certificate of analysis before cargo release.

Sourcing from Ningbo Kaaki Co., Ltd - Buyer Guidance

When sourcing from Ningbo Kaaki, buyers should request a technical data sheet that details solids content, viscosity, acid or hydroxyl number, and recommended application conditions. A safety data sheet complying with GHS classification is essential for handling and transport, and a certificate of analysis confirming the batch specifications should be obtained prior to shipment.

Typical minimum order quantities are around 500 kg per product grade, with lead times of 30‑45 days after order confirmation and receipt of required documentation. Buyers are advised to arrange pre‑shipment sampling, confirm compliance with REACH or TSCA as applicable, and clarify packaging preferences (drum vs. IBC) to align with their logistics chain.

What product categories does Ningbo Kaaki offer?

They list five chemical products, including water‑soluble alkyd resins (HS 3905.90), a waterborne UV‑curing polyurethane acrylate dispersion (HS 3909.50), and a linear polyester diol (HS 3907.99), plus two specialty diols without listed HS codes.

Which HS codes apply to the listed products?

The water‑soluble alkyd resin is classified under HS 3905.90, the UV‑curing PUA dispersion under HS 3909.50, and the PBA 1000 linear polyester diol under HS 3907.99. The remaining two products fall within Chapter 39 but have no specific HS code provided.

What typical specifications should a buyer verify for the water‑soluble alkyd resin?

Buyers usually check solids content (45‑55 wt %), viscosity (500‑2000 cP at 25 °C), acid value (30‑70 mg KOH/g), and water solubility. A certificate of analysis confirming these parameters is standard.

What documentation is commonly required for the UV‑curing PUA resin?

A safety data sheet (SDS), a technical data sheet (TDS) showing solids % (30‑60 wt %), viscosity range, UV‑curing speed, and a REACH compliance statement are typical. Test reports for gloss and hardness after UV exposure are also requested.

Are there standard certifications buyers should request for these chemicals?

Buyers often ask for ISO 9001 quality‑management certification, REACH registration for EU markets, and, where applicable, RoHS compliance. The supplier’s own certifications should be confirmed before purchase.

What are common packaging and shipment formats for these resins?

Resins are usually packed in 200‑L steel drums or 25‑kg IBC totes, palletized for ocean freight in 20‑ft or 40‑ft containers. FOB Ningbo or CIF destination ports are typical Incoterms.

What are typical minimum order quantities and lead times?

Minimum orders are often 500 kg per grade, with production lead times ranging from 30 to 45 days after receipt of a confirmed purchase order and required technical documentation.
