Products & Applications
What types of adhesive and sealant products do you manufacture?
We manufacture six product categories: contact adhesive (neoprene, SBS, water-based), spray adhesive (upholstery, foam, headliner, embroidery), shoe adhesive (PU, neoprene, primer), silicone sealant (neutral and acetoxy weatherproofing grades), PU foam (one-component, B1 flame-retardant, door/window), and construction adhesive (heavy-duty, multi-purpose nail-free). Each category includes multiple formulations for specific applications.
What is the difference between neoprene and SBS contact adhesive?
Neoprene (chloroprene rubber, CR) contact adhesive offers superior heat resistance (up to 120°C), stronger initial bond, and better chemical resistance. It is the premium choice for demanding applications like footwear and automotive. SBS (styrene-butadiene-styrene) contact adhesive is more cost-effective with good bond strength and longer open time, making it ideal for furniture, woodworking, and general-purpose bonding where extreme heat resistance is not required. See our detailed comparison at /guide/neoprene-vs-sbs-contact-adhesive.
Do you offer water-based or low-VOC adhesive options?
Yes. Water-based contact adhesive is a listed grade, and low-VOC reformulation is available across several lines. Other water-based adhesives — acrylic label and tape adhesives, foam and upholstery, PU shoe, textile lamination, wood, paper and packaging, and flooring — are assessed per application on our water-based adhesive pages, which state what is listed and what is not. Water-based products carry no flammable solvent and far less VOC; REACH and other compliance is declared per grade, not by carrier type. See /water-based-adhesives.
What substrates can your adhesives bond?
Our adhesive range covers a wide variety of substrates: leather (genuine and synthetic), rubber (natural, SBR, NBR), plastics (PVC, ABS, EVA, TPR, polypropylene with primer), foam (PU, PE, XPS, EPS), fabric, wood, plywood, MDF, HPL laminate, metal, glass, concrete, ceramic, and composite materials. Contact our technical team with your specific substrate combination for a recommendation.
What is the shelf life of your adhesive products?
Standard shelf life is 12 months from date of manufacture when stored properly (cool, dry, ventilated area away from direct sunlight and heat sources, temperature between 5°C - 35°C). Silicone sealant and PU foam products have a 12-month shelf life. Aerosol products (spray adhesive) should be stored upright. We mark production date and expiry date on every package.
Ordering & Payment
What is the minimum order quantity (MOQ)?
MOQs vary by product type: contact adhesive and shoe adhesive (liquid, drum/barrel) — 500 kg per SKU; spray adhesive and PU foam (aerosol) — 2,000 cans per SKU; silicone sealant and construction adhesive (cartridge) — 3,000 cartridges per SKU. Reduced trial order MOQs are available for first-time buyers to test the market.
How long does production take?
Standard production lead time is 7-15 days from order confirmation and deposit receipt, depending on order volume and product type. For OEM orders with custom packaging, add 7-10 days for label printing. Rush production is available for urgent orders with a priority surcharge. We recommend placing orders at least 4-6 weeks before your required delivery date.
What payment terms do you accept?
Standard terms are 30% T/T deposit, 70% balance against copy of B/L. For established partners with regular orders, we offer more flexible terms including L/C at sight, 60-day credit terms, or D/P. Western Union is accepted for sample orders. All prices quoted in USD.
Can I order samples before placing a bulk order?
Yes, and we encourage it. Samples are supplied free of charge, apart from a small number of specialised products quoted case by case. Courier freight is paid by the buyer, either on the buyer's DHL, FedEx or UPS account or prepaid and added to the sample invoice. A sample pack is ready in 5-7 working days and normally holds 2-3 variants so you can compare them on your own substrates; a sample built to a new custom formulation follows the development cycle of 2-4 weeks. Tell us the substrate, the bond you are making and the conditions it has to survive, and we will pick the grades worth testing.
Do you accept small trial orders for new markets?
Yes. We understand that entering a new market requires testing before committing to full container loads. Trial orders with reduced MOQs are available: 200 kg for liquid adhesive, 1,000 cans for aerosol products, and 1,500 cartridges for sealant. Trial orders can use simplified packaging (label-on-standard-tin) to reduce setup costs.
Shipping & Logistics
What shipping terms do you offer?
We offer FOB Guangzhou (buyer arranges ocean freight), CIF (we arrange freight to your port — cost, insurance, and freight included), and EXW (ex-works from our factory). Most customers choose FOB for better control over shipping costs, or CIF for a hassle-free delivered price. We can also arrange door-to-door delivery through our logistics partners.
How do you handle hazardous goods shipping for adhesive products?
Most solvent-based adhesives and aerosol products are classified as dangerous goods (DG Class 3 — flammable liquids, or Class 2.1 — flammable gas for aerosols). Our logistics team has extensive experience with DG shipping documentation including DG declaration, UN-certified packaging, MSDS, and proper labeling. We work with DG-certified freight forwarders to ensure smooth customs clearance at both origin and destination.
How many cartons/cans fit in a container?
Loading depends on product packaging: 20GP container holds approximately 800-1,000 cartons of 1L contact adhesive tins, or 15,000-18,000 cans of 450ml spray adhesive, or 20,000-25,000 pieces of 300ml silicone sealant cartridges. 40HQ containers hold approximately 2x the 20GP capacity. We optimize container loading to maximize space utilization and provide a detailed packing list with every shipment.
What export documentation do you provide?
Every shipment includes: commercial invoice, packing list, bill of lading (B/L), certificate of origin (CCPIT), MSDS/SDS, Certificate of Analysis (COA), fumigation certificate (when required). Additional documents available upon request: SGS inspection report, Form E (ASEAN), Form F (China-Chile FTA), REACH declaration, and country-specific certificates.
OEM & Custom Manufacturing
Can you produce adhesive under my own brand name?
Yes, OEM and private label manufacturing is one of our core services. We produce adhesives and sealants under your brand with custom packaging — your logo, color scheme, product name, and multilingual labels. We handle everything from packaging design to production and quality control. See our OEM & ODM service page for details: /oem-adhesive-manufacturing.
Can you develop a custom adhesive formulation for my specific application?
Yes, our R&D lab develops custom formulations based on your requirements — specific substrates, performance targets, environmental conditions, and regulatory standards. We can adjust existing formulations (viscosity, tack speed, open time, heat resistance) or develop entirely new products. Development timeline is typically 2-4 weeks for standard adjustments, 4-8 weeks for new formulations. See: /custom-adhesive-formulation.
What packaging options are available for OEM orders?
We offer a full range of packaging: metal tins (100ml-20L), drums (50L, 200L), aerosol cans (300ml-750ml), cartridges (260ml-600ml), tubes (50ml-200ml), HDPE bottles, pails (5-20kg), and bulk containers. Labeling options include paper labels, vinyl stickers, shrink sleeves, and direct-print on metal tins. All packaging can be fully customized with your branding. See: /private-label-adhesive.
Certifications & Compliance
What certifications does your factory hold?
Our factory is ISO 9001:2015 (quality management) and ISO 14001:2015 (environmental management) certified. Products are tested and certified by SGS. We provide REACH compliance declarations for EU markets, RoHS compliance for applicable products, and GHS-compliant MSDS/SDS documentation in multiple languages. See our certifications page for full details: /certifications.
Can your products meet REACH compliance for EU export?
Yes, we manufacture REACH-compliant products for the European market. All raw materials used in EU-destined products are screened against the SVHC (Substances of Very High Concern) candidate list. We provide REACH compliance declarations, VOC test reports, and SDS documents compliant with EU CLP regulation. We can also formulate low-VOC and toluene-free variants specifically for EU requirements.
Do you provide MSDS / Safety Data Sheets?
Yes, every product is accompanied by a comprehensive GHS-compliant Material Safety Data Sheet (MSDS/SDS). Our SDS documents are available in English, French, Arabic, Spanish, and Portuguese. They cover all 16 sections required by GHS: hazard identification, composition, first-aid measures, firefighting, handling and storage, exposure controls, physical properties, stability, toxicological information, ecological data, disposal, and transport information.
