Dalian Liansheng New Materials is presented as a source-reviewed supplier profile centered on Epoxy resins and specialty epoxy resins, with company-published capability separated from buyer-side verification requirements.
Dalian Liansheng New Materials Group Co., Ltd. (Liansheng Group / LIANSHENG GROUP) is a mainland-China resin supplier headquartered in Dalian, Liaoning. Its current Chinese and English websites present the legal identity, address, telephone, company-domain email, Liaoning ICP filing and group mark. The site says the group was established in 2006; its history records the Dalian factory entering production in 2021, while company news says specialty epoxy resins and curing agents are made at its own factory. It also describes Dalian and Changzhou laboratories, 15 application engineers, and technical support for coatings, adhesives, composites, metalworking fluids, textiles and polymer modification. The composite division serves wind-energy, copper-clad-laminate, encapsulant, vessel and pipeline customers with resins, curing agents and additives. China Composites Expo lists the company at booth 6H07 under epoxy resin, phenolic resin and additives. The site also lists partner brands including Nanya, Huntsman, Cabot, BYK, Mitsubishi Gas Chemical, Kumho and PQ. Those materials are treated as cooperative or distributed products and are not automatically attributed to Liansheng manufacturing. The Chinese legal name, English exhibitor name, group brands, older Dalian Liansheng Trading wording and dlliansheng.com domain have been reviewed as one group profile. Named subsidiaries remain separate legal entities.

This procurement profile is built for formulators, processors and procurement teams comparing chemistry, processing window, cured performance and regulatory documentation. It organizes Dalian Liansheng New Materials Group Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Dalian Liansheng New Materials Epoxy resins and specialty epoxy resins.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.
Dalian Liansheng New Materials Group Co., Ltd. currently lists 9 product or service groups and 8 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.
Liansheng's official catalog covers resins, curing agents, diluents, tougheners, accelerators, functional additives, BYK additives and polyurethane. It combines group-produced and partner-brand grades. Every RFQ should therefore identify the manufacturer, legal producer, production site, origin, brand authorization and whether Liansheng acts as manufacturer, agent, distributor or technical-service provider. For Liansheng-produced specialty epoxies or hardeners, request the current TDS, SDS, COA template, change controls, lot identity, retention sample and complaint traceability. For partner brands, verify current authorization, delivery channel and anti-counterfeit traceability rather than treating distributor data as Liansheng factory capability. A composite RFQ should define resin chemistry and grade; curing and accelerator package; mix ratio; viscosity and temperature window; pot life or gel time; exotherm; cure and post-cure; reinforcement and sizing compatibility; process; laminate construction; and applicable mechanical, thermal, chemical, weathering, fire and smoke tests. Wind, copper-clad-laminate, electronic-encapsulant, tank and pipe projects need use-specific evidence; generic neat-resin values do not validate a final formulation or laminate. The site describes Dalian and Changzhou application centers with 15 engineers, but buyers should still run a representative trial with the actual reinforcement, filler, pigment and equipment, then control the approved formula and sample. Lock packaging, dangerous-goods status, storage, shelf life, manufacturing date, MOQ, lead time, transport temperature, Incoterm and destination compliance documents. The site has an English entry but public evidence emphasizes domestic users and a Chinese sales network; no references or documentation sufficient to establish repeatable export delivery was found, so this profile is not marked export-ready. HTTP content is available, but the HTTPS certificate was expired during the 2026-08-13 review. Do not submit formulas or payment data through the unencrypted site; independently verify the email, account and payee. No current management-system certificate with number, edition, scope, issuer record and validity was found, so none is recorded. Company scale, partner, factory and product claims require license, authorization, batch-record and audit verification.
No company-level certification is listed on this profile.
Evaluate Dalian Liansheng New Materials Group Co., Ltd. as a potential composite resin supplier for Epoxy resins and specialty epoxy resins, verify the public evidence and prepare a comparable RFQ.
Dalian Liansheng New Materials Group Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.
For Epoxy curing agents and specialty hardeners, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Dalian Liansheng New Materials Group Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Dalian Liansheng New Materials Group Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.
Dalian Liansheng New Materials Group Co., Ltd. publishes Specialty epoxy-resin and curing-agent R&D and production as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.
The relevance of Resin, curing-agent and additive package selection depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, Composite formulation and application support is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.
Dalian Liansheng New Materials Group Co., Ltd.'s public scope suggests a potential route for piping, tanks or corrosion-resistant process equipment. The RFQ should define service chemistry, temperature, pressure or stiffness class, liner, structural wall, joints, supports, nozzles, inspection and transport. Project-specific design and evidence remain necessary before the supplier can be treated as a fit.
Dalian Liansheng New Materials Group Co., Ltd.'s chemistry portfolio can be evaluated for the named composite process only after the processing window and cured-property basis are aligned. Request current data sheets, grade and site identity, viscosity or mix control, cure and exotherm, storage, batch certificate fields and test evidence based on the intended reinforcement and construction.
Dalian Liansheng New Materials Group Co., Ltd.'s product references indicate a possible fit for transport applications. Qualification should address part revision, material and process, appearance class, dimensional capability, inserts and secondary operations, validation plan, change control, annual volume, service-part obligations and packaging that prevents cosmetic or structural damage.
Dalian Liansheng New Materials Group Co., Ltd.'s source record currently includes Official Dalian Liansheng Website, Official Liansheng English Website, Official Liansheng Group Profile and History, Official Liansheng Product Center. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
No company-level certification is presently listed in the reviewed profile. That does not prove that no document exists, but it means the RFQ should ask for the quality-system certificate and every product-specific test or approval needed by the buyer rather than assuming a certification from market reputation.
GetFRP last recorded a public-source review date of 2026-08-13. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.
