I. The Core Logic Behind Factory-Direct Pricing
Why are factory-direct prices for adhesives lower? Because intermediate links are eliminated—specifically, the markups added by distributors and wholesalers (totaling 20% to 40%) are removed, allowing manufacturers in key industrial hubs (e.g., electronic adhesives in Guangdong, PUR in Shandong, hot-melt adhesives in Zhejiang, and sealants in Hebei) to supply products directly at ex-factory prices.
Characteristics of direct pricing include: lower prices for higher volumes (tiered pricing based on drums or tons);
a focus on in-stock availability (standard adhesive types ship within 48 hours); and price fluctuations linked to raw materials (such as epoxy resin, silicone monomers, and EVA feedstock).
Actual factory-direct quotes (based on data from platforms like 1688/Alibaba and industrial hub statistics) are as follows: epoxy potting compounds, 20–31 RMB/kg; silicone sealants, 15–48 RMB/kg; EVA hot-melt adhesive pellets, 13–20 RMB/kg; PUR, 28–66 RMB/kg; and electronic-grade silicone, 85–104 RMB/kg.
The trade-off for direct pricing is that the buyer handles service-related tasks independently—without the technical support or credit terms typically provided by distributors, the purchaser must manage product selection, testing, and inventory control themselves.

Epoxy-Based Products: Potting Compounds and AB Adhesives
Factory-direct prices for epoxy adhesives vary according to their specific applications.
Epoxy Potting Compounds (for electronics potting and electrical encapsulation): Approx. 19.91–31.40 RMB/kg (Source: Alibaba China – Guangzhou Sanjin: ~19.91–25.39 RMB; Huizhou Jincheng: ~24.85–31.40 RMB; minimum wholesale order of 15–20 kg) – Used for waterproofing and insulating circuit boards and motor coils. Two-component AB Structural Adhesives (high-strength bonding for metal/non-metal): Approx.
58.92–60.79 RMB/set (Source: Made-in-China – Dongguan Sanbang; equivalent to Araldite AW106/HV953) – General-purpose structural bonding. Electronic Encapsulation-grade Epoxy (high hardness, waterproof, high-temperature resistant): Starting at ~99 RMB/kg – Electronic grade is 3–5 times more expensive than industrial grade.
Key points for selection: Match the product to the application (potting/bonding/encapsulation);
when inquiring about prices, specify “curing hardness + temperature resistance + insulation” for potting compounds, and “substrate material + strength (MPa)” for AB adhesives – accurate specifications ensure accurate price quotes.
III.
Sealants: Silicone Sealants
Factory-direct prices for silicone sealants vary by grade.
Industrial-grade Silicone Sealants (resistant to high/low temperatures, pressure, water, and oil): Starting at ~15 RMB/kg (Source: 1688 – Shenzhen Meigui Hongye industrial structural adhesive; Foshan Xidi Xilu 588 silicone sealant; temperature range: -60°C to 300°C) – Sealing for general equipment and multi-material metal assemblies.
Mid-to-high-end Silicone (weather-resistant type): Approx. 26.66–48.57 RMB/kg (Source: Zhuhai Shuangtan) – Architectural curtain walls and outdoor weather-resistant applications.
Electronic-grade, flame-retardant, two-component silicone (for electronic component potting): approx. 85.84–104.08 RMB/kg (Yantai Jianbang; 1 kg minimum order)—a premium price tier for electronic protection.
Retail packaging (standard 310ml cartridge): standard neutral silicone is approx. 5–15 RMB/cartridge; branded products (e.g., Guibao, Huitian) are approx. 10–25 RMB/cartridge—wholesale purchasing by the kilogram saves over 50% compared to buying individual cartridges.
Key tips for selecting silicone sealant: specify the “temperature resistance range,” “substrate material,” and “acidic vs. neutral type” when inquiring about prices;
industrial-grade products fall in the 15 RMB range, while electronic-grade ones are in the 100 RMB range—do not expect to buy electronic-grade products at industrial-grade prices.
IV.
Hot-Melt Adhesives: EVA and PUR
Hot-melt adhesives are the category offering the greatest advantages for bulk purchasing. EVA hot-melt adhesive pellets (general-purpose for packaging and bookbinding): approx.
13.43–20.18 RMB/kg (Zhejiang Minghui; 100 kg minimum wholesale order)—the best value-for-money option among bulk hot-melt adhesives. PUR hot-melt adhesive (moisture-curing; for flat lamination/wrapping): approx. 28.02–66.80 RMB/kg (Huzhou Haojing Environmental: approx. 28.02–40.03 RMB; PUR for door frame wrapping: approx. 40.08–66.80 RMB)—used for furniture edge banding, automotive interiors, and textile lamination; while 1–2 times more expensive than EVA, it offers superior weather and temperature resistance.
Hot-melt adhesive sticks (for manual use/small batches): approx. 2.67–3.94 RMB/piece (Hebei Pengda; 720-piece minimum wholesale order)—for small retail orders.
Key points for selecting hot-melt adhesives: When inquiring, ask for “softening point + open time” for EVA and “curing speed + temperature resistance” for PUR. Unit prices for ton-scale purchases can be further reduced by 10% to 20%—hot-melt adhesives are the category where price is most elastic relative to volume.
V.
Negotiation points for securing direct-sales pricing
Six key points for obtaining genuine direct-sales prices.
State purchase volume: Factory quotes are tiered by volume (sample price for 1 kg; wholesale price for 15–100 kg; lowest price for ton-scale orders); specifying monthly or annual volumes is essential to secure the corresponding price.
Source directly: Buy directly from industrial hubs—Guangdong (electronics adhesives), Shandong (PUR), Zhejiang (hot-melt adhesives), and Hebei (sealants)—to bypass traders.
Negotiate tiered pricing: Include annual volume frameworks in the contract (e.g., 500 kg at Price X, 2 tons at Price Y) to lock in price reductions.
Sample verification: Direct sales often involve unbranded products;
test viscosity, curing, and strength, cross-reference with the Technical Data Sheet (TDS), and retain samples for comparison.
Compare three suppliers: Request quotes for the same specifications from three factories in the relevant industrial hub;
a price difference of over 10% suggests the quote is inflated. Cash vs. credit terms: Prepayment or immediate settlement can secure an additional 1% to 3% discount.
The essence of direct-sales pricing is “trading procurement expertise for a better price”;
by executing the four steps—volume, sourcing location, verification, and negotiation—adhesive procurement costs can be driven down to the industrial hub’s baseline.
Conclusion
What are the factory-direct prices for industrial adhesives? Epoxy potting compounds: 20–31 RMB/kg; AB structural adhesives: approx. 59 RMB/set; silicone sealants: 15–48 RMB/kg (electronic grade: 85–104 RMB/kg); EVA hot-melt adhesives: 13–20 RMB/kg; PUR hot-melt adhesives: 28–66 RMB/kg—these are 20% to 40% lower than distributor prices.
By submitting volume-based inquiries, sourcing directly from the production origin, verifying samples, and negotiating based on price comparisons, you can secure genuine rock-bottom industrial-cluster pricing—equivalent to factory-direct rates for adhesives.
