Frequently Asked Questions

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, acetoxy, structural, weatherproof), PU foam (one-component, fire-rated, door/window), and construction adhesive (heavy-duty, multi-purpose nail-free). Each category includes multiple formulations for specific applications.

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 /blog/neoprene-vs-sbs-contact-adhesive.

Yes, we manufacture water-based contact adhesive, water-based shoe adhesive, and low-VOC formulations across multiple product lines. These products are designed for markets with strict environmental regulations (EU, North America) and for buyers pursuing green building certifications. Water-based products have zero flammable solvents, dramatically reduced VOC emissions, and are REACH compliant.

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.

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.

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.

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.

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.

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.

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.

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.

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.
