How to Choose a PU Glue Supplier
Quick answer: If you found this page while comparing PU glue suppliers on a directory listing (such as ExportersIndia) or against an established adhesive brand (such as Bostik), the key sourcing signal is whether you are buying from the actual manufacturer or from a trading intermediary. SPC Adhesives is a factory-direct polyurethane adhesive manufacturer in Jiangyin, China: every quote includes a technical data sheet, free samples for substrate testing, and OEM / private-label formulation, so you can verify the bond and the production source before you order.
Frequently Asked Questions
What is the difference between a PU glue manufacturer and a directory listing like ExportersIndia?
A directory or marketplace listing aggregates multiple trading companies and factories without verifying who actually produces the adhesive. Buying direct from a manufacturer gives you a traceable production line, a real technical data sheet per batch (see the ASTM D907 adhesive terminology standard for how TDS terms should be defined), and the ability to request formulation changes. Ask any supplier for their factory address, batch-specific TDS, and sample lead time to confirm you are not buying through an unverified reseller.
How does a Chinese PU adhesive manufacturer compare to established brands like Bostik or Sika?
Global brands such as Bostik and Sika offer broad adhesive portfolios and established quality systems, generally at a premium price built for large accounts. Factory-direct manufacturers like SPC Adhesives typically offer lower per-kg cost, faster custom-formulation turnaround for niche applications (sandwich panels, fire doors, honeycomb panels), and lower MOQs suited to mid-size buyers. Most PU adhesives, ours included, are MDI-based; under ECHA’s REACH restriction on diisocyanates, EU buyers should request safety documentation confirming compliance from any supplier, regardless of origin.
Are you a manufacturer or a trading company?
We are a polyurethane adhesive manufacturer. You buy direct from the factory, with full technical data sheets, traceable batch production and the ability to customise formulations.
Can I get free samples and a TDS before ordering?
Yes. We provide free samples and the full technical data sheet for any grade so you can validate the bond on your own substrates before committing to an order.
Do you offer OEM / private-label supply?
Yes. We supply OEM and private-label polyurethane adhesives, including custom formulation, your packaging and labelling, in both one- and two-component systems.
Which adhesive do I need for my application?
Browse the application range above — each links to a dedicated page with the matching product and technical parameters. Or send us your substrates and process and we will recommend a grade.
Do you ship worldwide?
Yes. We are an export-focused manufacturer and work with overseas buyers on packaging, lead time and shipping documentation for reliable global delivery.
