Specifications are based on Dongsen’s current approved product data source.
SA-1007 can be used as a polyisocyanate hardener in 2K polyurethane adhesive formulations for footwear and shoe-sole bonding applications.
It is supplied in ethyl acetate as an upstream crosslinker / curing-agent raw material. Dongsen does not supply finished footwear adhesives.
Final suitability should be validated in the customer’s actual adhesive formulation and production process conditions.
When to consider SA-1007
Consider SA-1007 when evaluating a polyisocyanate hardener for a 2K PU footwear or shoe-sole adhesive formulation and the required hardener specification is aligned with the SA-1007 profile.
Primary selection signal
SA-1007 is specified at NCO 7.5 ± 0.3% with 40 ± 1% solids and free monomer ≤0.1%. Refer to Technical Data for the full confirmed specification set.
Related SA grades
SA-1003 and SA-1009 can also be reviewed when a different SA-series specification profile is required. Final grade selection should be validated in the customer’s own adhesive formulation and process.
What is SA-1007?
SA-1007 is a polyisocyanate hardener / crosslinker for 2K polyurethane adhesives used in footwear and shoe-sole applications.
What are the main SA-1007 specifications?
Dongsen’s current product data lists 40 ± 1% solids, NCO 7.5 ± 0.3%, free monomer ≤0.1%, viscosity approximately 11 cps at 25°C, and ethyl acetate as the carrier.
What is SA-1007 used for?
SA-1007 is used as the polyisocyanate hardener component in 2K PU adhesive formulations for footwear and shoe-sole bonding. Final suitability should be validated in the customer’s actual formulation and process conditions.
How does SA-1007 differ from SA-1003 and SA-1009?
The current SA-series specifications differ mainly in solids and NCO profile. SA-1007 is specified at 40 ± 1% solids and NCO 7.5 ± 0.3%. SA-1003 is 40 ± 1% solids with NCO 7.2 ± 0.3%, while SA-1009 is 20 ± 1% solids with NCO 4.2 ± 0.3%. These specification differences should be evaluated in the customer’s own adhesive formulation rather than interpreted as universal performance differences.
Does Dongsen supply finished footwear adhesives?
No. Dongsen supplies polyisocyanate hardeners and crosslinking raw materials for adhesive formulations, not finished footwear adhesives.
