Specifications are based on Dongsen’s current approved product data source.
SA-1009 is a polyisocyanate hardener used to formulate 2K PU adhesives for shoe and footwear applications, including shoe-sole bonding.
Dongsen supplies the hardener / crosslinker raw material rather than a finished adhesive.
Final suitability should be validated in the customer’s actual formulation and process conditions.
When to Consider SA-1009
Consider SA-1009 when evaluating an SA-series polyisocyanate hardener for a 2K PU footwear adhesive formulation where the required hardener specification is around 20 ± 1% solids.
Confirmed Selection Signal
SA-1009 is the 20 ± 1% solids grade in the currently listed SA range. Refer to Technical Data for its NCO, free-monomer, viscosity and carrier specifications.
Grade Selection Boundary
SA-1003 and SA-1007 are related SA-series grades but are not automatic replacements for SA-1009. Final grade selection should be validated against the customer’s resin system, formulation target and production process.
What is SA-1009?
SA-1009 is a polyisocyanate hardener used to formulate 2K PU adhesives for shoe and footwear applications, including shoe-sole bonding. It is a raw-material hardener rather than a finished adhesive.
What are the key specifications of SA-1009?
Dongsen’s current approved product data lists SA-1009 at 20 ± 1% solids, NCO 4.2 ± 0.3%, free monomer ≤0.1%, approximate viscosity 11 cps at 25°C, with Ethyl Acetate as the carrier.
What application is SA-1009 intended for?
SA-1009 is positioned as a polyisocyanate hardener for 2K PU shoe and footwear adhesives. Final suitability should be validated in the customer’s own formulation and process conditions.
What distinguishes SA-1009 within the current SA range?
SA-1009 is listed at 20 ± 1% solids, while SA-1003 and SA-1007 are listed at 40 ± 1%. This is a specification difference for grade selection, not a performance or superiority claim.
