Key features

Superior Adhesion on Difficult Substrates: Bonds permanently to asphalt, steel, rust, and MDF where water-based primers fail.

Eliminate Bond Failure on Problematic Bases: One epoxy replaces three primers:no more delamination or costly callback repairs.

100% Solids Content, Zero VOC: 100% solids, zero VOC:safer application in enclosed spaces, no solvent fumes.

Ultimate Foundation for Heavy-Duty Flooring: Indestructible base under self-leveling for factories, cold storage, food plants.

Outperforms Water-Based Primers: Delivers 3times the bond strength of water-based primers on non-porous surfaces.

Complete Moisture Barrier Protection: Seals capillary pores, blocks rising damp that causes blistering and bubbling.

Ready for Quartz Sand Broadcast: Wet-state accepts 50 to 70 mesh sand to create a mechanical key layer.

No Dilution, No Water, No Guesswork: Mix A+B and apply directly : no water, no ratio errors, no variance.

AI-Powered supplier vetting

SummaryShanghai Languan New Building Materials Co., Ltd. is described as a developer, manufacturer, and seller of environmentally friendly building decoration materials. Its stated scope covers building materials, floor-related solutions, machinery and equipment, hardware, chemical products, communication equipment, and import/export and technical services. The supplier reports OEM service for well-known brands, quality assurance, documented complaint-handling and corrective-action procedures, and facilities including mixing, self-leveling, and automatic packaging lines. However, it has no available SDK, no stated AI-based decision-management practice, no inventory capability, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial information is limited to years identified as 2021–2023 without performance values. Certification, customer cases, and detailed customization evidence are not sufficiently documented.

Supplier typeThe supplier is presented as Shanghai Languan New Building Materials Co., Ltd., focused on R&D, production, and sales of environmentally friendly building decoration materials. Its business scope includes building materials, insulation materials, sealing fillers, cement products, machinery, hardware, chemical products, and related sales and import/export activities, supporting classification as a building-material manufacturer and supplier.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaint handling, and describes providing technical guidance and comprehensive customer services. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.

R&D capabilityThe company describes R&D activity and the ability to develop new materials using existing technology, and its culture emphasizes innovation. However, it explicitly has no available SDK and has not established an AI model for big-data decision support; these limitations prevent a broad conclusion that its innovation capability exceeds requirements.

Production capacityThe supplier states that it conducts production and lists processing and manufacturing activities, with a mixing line, self-leveling production line, and automatic packaging robot. Quality assurance and documented corrective-action procedures are also reported, although there is no valid contract with affiliated subcontractors and no in-stock capability.

Customization capabilityThe supplier reports OEM services for well-known brands and says it provides solutions for difficult floors, technical guidance, and development of various new materials using existing technology. This directly supports some customization and OEM capability, although the slices do not specify product scope, minimum quantities, lead times, or engineering resources.

Product Q&A

Q:What is the difference between 680 and LG670?

LG670 is a single-component water-based primer with quartz granules for smooth tiles/stone. 680 is a two-component solvent-free epoxy for far harder substrates (asphalt, steel, metal, old paint, MDF) with much stronger bonding and sealing.

Q:Can 680 be applied directly on asphalt/bitumen?

Yes. 680 is designed exactly for asphalt/bitumen that ordinary primers cannot grip; epoxy anchoring forms a strong bond layer : the required primer for asphalt flooring renovation. Ensure stable, clean, dry asphalt first.

Q:Can 680 be used on steel plate and metal?

Yes. 680 works on steel plate, aluminum, galvanized steel, and wrought iron. After degreasing and derusting, it forms a strong sealing bond layer before self-leveling or epoxy : ideal for industrial steel-deck flooring.

Q:How long before I can pour self-leveling after 680?

680 is touch-dry in about 8-12h and fully cured in about 24h (per factory TDS). Pour K18/K19/K50 self-leveling after full cure for reliable bond and strength.

Q:Is customization available for this product?

Yes, we offer full customization, minor customization, and options from samples or designs.
