About Deqing Yinlong Industrial Co., Ltd. - Industrial Chemicals Supplier in China

Deqing Yinlong Industrial Co., Ltd. is based in China and currently lists five distinct products in its catalogue. The company classifies its offerings under the industrial chemicals and adhesive, sealants & lubricants categories. The product lineup includes glycerol ester of gum rosin, pentaerythritol ester of rosin, rosin modified maleic anhydride resin, alcohol soluble fumaric acid resin, and a hot‑melting road‑marking resin. These compounds are typical rosin‑derived chemicals used as modifiers, tackifiers, or resin bases in various formulations. In international trade they fall within HS Chapter 38 for organic chemicals and often under HS 3506 for adhesives and sealants.

The glycerol ester and pentaerythritol ester products are water‑soluble rosin derivatives that provide low‑temperature flexibility in adhesive systems. Rosin modified maleic anhydride resin is a polymerizable ester employed in coating binders and thermoset applications. Alcohol soluble fumaric acid resin offers high reactivity for polyester and epoxy formulations. The hot‑melting road‑marking resin is formulated for rapid‑cure traffic marking paints. All five items are supplied in bulk packaging suitable for container shipment.

Product Range and Specialties of Deqing Yinlong Industrial Co., Ltd.

Deqing Yinlong’s catalogue focuses on rosin‑based intermediates. Glycerol ester of gum rosin typically exhibits an acid value of 30 - 45 mg KOH/g and a softening point around 70 °C, making it suitable for water‑based adhesive tackifiers. Pentaerythritol ester of rosin often has a higher molecular weight, with a melt viscosity of 2 000 - 4 000 cP at 120 °C, used in hot‑melt adhesives.

Rosin modified maleic anhydride resin is commonly supplied with a maleic anhydride content of 20 - 30 % and a glass transition temperature (Tg) near 60 °C, fitting polyester resin blends. Alcohol soluble fumaric acid resin is marketed with a fumaric acid purity above 95 % and a solubility in ethanol of 10 % w/w. The hot‑melting road‑marking resin is formulated to melt at 120 - 130 °C and solidify quickly, complying with traffic‑marking performance standards such as ASTM D4958. Industry buyers usually request material safety data sheets (MSDS) and technical data sheets that confirm these parameters.

Trade and Export Information - Deqing Yinlong Industrial Co., Ltd.

China is a major exporter of rosin‑derived chemicals, supplying Europe, North America and Southeast Asia with bulk shipments. Buyers typically import these products under HS 3506 (adhesives and sealants) or HS 3824 (polyesters and other polymeric materials). Common certifications demanded by importers include ISO 9001 quality management, REACH registration for the European Union, and TSCA compliance for the United States.

Standard logistics involve 20‑ft or 40‑ft containers packed in sealed drums or intermediate bulk containers, often shipped FOB Shanghai or Ningbo. Incoterms such as CIF Europe or FOB US Gulf ports are frequently used. Export documentation generally includes a commercial invoice, packing list, certificate of origin, and, where required, a REACH safety data sheet. Seasonal demand peaks in the spring for road‑marking resins and in the autumn for adhesive tackifiers.

Sourcing from Deqing Yinlong Industrial Co., Ltd. - Buyer Guidance

Prospective buyers should request the latest material safety data sheet, a full technical data sheet, and, if applicable, REACH registration numbers before placing an order. Samples of 1 - 5 kg are typical for performance testing, and buyers often verify melt viscosity, acid value and softening point against the supplied specifications.

Minimum order quantities usually start at one 20‑ft container (approximately 10 t) for bulk resin grades, though smaller shipments may be arranged in 200 kg intermediate bulk containers. Lead times reported by Chinese exporters range from 30 to 45 days after order confirmation, subject to production scheduling and shipping slot availability. Verification of ISO 9001 certification or equivalent quality system is advisable as part of supplier due diligence.

What types of rosin derivatives does Deqing Yinlong offer?

The company lists glycerol ester of gum rosin, pentaerythritol ester of rosin, rosin modified maleic anhydride resin, alcohol soluble fumaric acid resin, and a hot‑melting road‑marking resin, all classified under industrial chemicals and adhesive categories.

Which HS codes are typically applied to these products?

In customs classification they fall under HS Chapter 38 for organic chemicals, with specific sub‑headings such as 3506 for adhesive‑related resins and 3824 for polyester‑type resins, depending on the exact formulation.

What standard specifications should buyers verify?

Buyers usually check acid value, softening point, melt viscosity, maleic anhydride content, and purity percentages as listed in the technical data sheet; these parameters align with industry standards for rosin‑based adhesives and coatings.

What documentation is recommended before ordering?

Request a current material safety data sheet, technical data sheet, REACH registration proof (for EU shipments), and evidence of a quality management system such as ISO 9001 certification.

What are typical packaging and shipping formats?

Products are shipped in sealed steel drums (200 kg) or intermediate bulk containers, consolidated into 20‑ft or 40‑ft containers; FOB Shanghai and CIF Europe are common Incoterms used.

What are the usual minimum order quantities and lead times?

Minimum orders are generally one 20‑ft container (≈10 t) or a single 200 kg drum for trial, with lead times of 30 - 45 days from order confirmation, depending on production scheduling and freight availability.
