Specification and supply checklist

QSYW1000 grade identity
Specify PAA / QSYW1000, CAS 9003-01-4. The reference belongs to this liquid grade; do not apply its limits to QSYW2000, QSYH1003 or another acrylic polymer without separate documents.
Solids and residual monomer
The reference lists at least 40.0% solids and no more than 1.0% free monomer calculated as acrylic acid. Confirm the analytical basis, methods and any tighter limits required by your process.
Compatibility and phosphorus requirements
Retain the manufacturer warning against mixing QSYW1000 with PCA. A phosphorus-free polymer does not make a complete formulation phosphorus-free; identify the other ingredients and your finished-product requirement.
Qualification and order information
Provide the intended process, evaluation plan, quantity with units, package and destination. Request the current QSYW1000 TDS and SDS and identify the batch-COA parameters needed before approving an order.

Start with your application

Cooling-water scale and dispersion control

Describe the calcium-carbonate deposit problem, water conditions and other treatment ingredients. Define the scale-inhibition and particle-dispersion results required for your application.

Boiler and desalination formulations

For boiler or desalination work, specify the process, operating conditions and equipment requirements. The manufacturer lists these uses, but the selected QSYW1000 grade still needs application qualification.

Formulation compatibility

List all co-ingredients. The manufacturer warns against mixing QSYW1000 with PCA because precipitation may occur; confirm the exact referenced material and your formulation compatibility with the technical team.

Request the documents for your grade

Use the TDS for product review, the SDS for handling and regulatory review, and a relevant COA for batch-level checks.

PAA · QSYW1000 buying questions

Are PAA and QSYW1000 separate entries here?

The manufacturer identifies QSYW1000 as a polyacrylic acid grade, so this page treats them as one entry. Its reference values are specific to QSYW1000 and must not be substituted for QSYW2000, QSYH1003 or another polymer grade.

Can QSYW1000 be mixed with PCA?

The manufacturer advises against that mixture because precipitation may occur. Confirm the exact material referred to as PCA and review the complete formulation with your technical team. The abbreviation has not been expanded here without supporting identification.

Does phosphorus-free PAA make my treatment program phosphorus-free?

The description applies to this acrylic polymer. Other formulation ingredients may change the phosphorus content of the finished treatment. Review the complete formulation and define any analytical limit your customer or process requires.

What should I check when comparing QSYW1000 pH results?

The reference pH range of 2.5–5.0 is measured in a 1% water solution. Compare results at the same solution concentration and using agreed methods. The density reference of at least 1.150 g/cm³ is specified separately at 20°C.
