Key features

Good hydrolysis stability; does not gel easily during storage. Optimised esterification and distillation processes ensure the product does not undergo premature hydrolysis and become cloudy in humid.

It has a longer shelf life once opened, reducing raw material wastage, and is suitable for mass production in investment casting and anti-corrosion coatings.

Viscosity, distillation fractions and reaction rates are tailored to established processes for precision casting, high-temperature paints and ceramic binders.

AI-Powered supplier vetting

SummaryQinmu is a specialty and functional chemical manufacturer focused on pharmaceutical intermediates and related materials. It reports production and sales operations, an Indian branch, international chemical partnerships, export activity, and historical ISO9001 and ISO14001 certification. The supplier provides flexible customization, including sample-, design-, minor-, and full-customization options, and offers ODM services, but does not provide 3D software design, SDKs, or documented new-product development in the past year. Quality controls include raw-material traceability, quality assurance, and random finished-product inspection, although only one quality inspector is reported and packing staff perform finished-product checks. The supplier reports inventory capability and lead times within 15 workdays in both peak and off-season periods, but lacks overseas warehouses, showrooms, agents, or branches apart from the stated Indian branch information. Financial records are identified for 2021–2023, but no...

Supplier typeThe supplier is identified as a specialty chemical producer and seller specializing in pharmaceutical intermediates, PETMP, 3-Mercaptopropionic acid series, and other functional chemical materials. It is explicitly not classified as a professional technical supplier.

CertificationsThe company description states that it passed ISO9001 and ISO14001 certification in 2019. No current validity period, certificate scope, or additional certifications are provided.

R&D capabilityThe supplier offers ODM services and customization from samples and designs, but reports no new products in the past year, no SDK, no 3D software design service, and no professional technical-supplier R&D capability. This supports development-related customization but not demonstrated recent product innovation.

Production capacityThe supplier reports production of pharmaceutical intermediates and functional chemical materials, inventory capability, ten qualified service-capability suppliers, and average lead times within 15 workdays in both peak and off-season. Quality inspection is limited by the reported single inspector and random finished-product inspection conducted by packing staff.

Customization capabilityThe supplier explicitly supports flexible customization, customization from samples, minor customization, full customization, and customization from designs, and also provides ODM services. It does not provide 3D software design services, so customization is supported without evidence of advanced digital design capability.

Product Q&A

Q:What is the content of Si in your ethyl silicate? How much is the free acid? Is the shell strength stable or not?

Regular Si28 and Si40 are available in stock. The free acid content is extremely low, and the hydrolysis is uniform without rapid gelation. The shell strength of the surface layer and the back layer is stable, without cracking.

Q:How is the hydrolysis rate? How is the temperature resistance and adhesion of the formed paint film?

The curing rate is moderate, and the film formation is dense; it has good heat resistance, waterproof and anti-corrosion properties, and is suitable for high-temperature resistant primers and inorganic ceramic coatings.

Q:How long is the delivery period? What are the packaging specifications?

In stock. Hazardous chemical logistics will be arranged within 7 days. 190kg iron drums, tanker drums, and bulk tankers can be provided. Arrangement will be made according to demand.
