Can I get a free sample?

Yes. Most manufacturers provide 500g-1kg free samples. The customer only needs to pay for international courier shipping.

What is the minimum order quantity (MOQ)?

Factory bulk orders typically 1 ton (1000kg). Sample trial orders can be as low as 1kg.

What payment methods do you accept?

Common is T/T (30% deposit + 70% against B/L copy). L/C is acceptable for large orders.

Key features

Water Retention Expert: Locks in moisture effectively to prevent cracking, making it the "perfect partner" for cement and tile adhesives.

Stable Performance: Resists acids, alkalis, and salts (non-ionic); non-toxic, odorless, and completely safe.

Hot & Cold Compatibility: Dissolves readily in cold water and turns into a gel upon heating (reversible).

Smooth Application: Increases viscosity and lubricity, making paints and mortars much easier to apply.

AI-Powered supplier vetting

SummaryQingdao New Sanda Industry Co., Ltd. is identified as both a trading company and manufacturer/factory in China, focused on chemicals and construction-related products. The supplier reports ISO-series management certifications, two production lines, 21–30 quality-control staff, and peak- and off-peak order fulfillment within 15 working days. Its stated capabilities include R&D, customized formulations, formulation optimization, application testing, troubleshooting, multilingual documentation, and after-sales support. The supplier reports extensive export coverage and began exporting in 2015, but the available trade evidence shows only one recorded transaction and one associated buyer. Financial credibility cannot be assessed because financial data is excluded from evaluation.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its stated business focuses on chemical products and industrial additives, including Titanium Dioxide, HPMC, VAE, HEC, CMC, and related materials.

CertificationsThe supplier lists ISO 9000, ISO 14001, ISO 9001, ISO 14000, and ISO 20000 certifications. These stated certifications provide explicit evidence of certified management-system coverage, although the slices do not provide certificate numbers, validity dates, or scope details.

After-Sales capabilityThe supplier states that it provides after-sales service, multilingual documentation, formulation optimization, application testing, and troubleshooting. These are explicit service offerings supporting customers after product delivery.

R&D capabilityThe supplier describes a dedicated R&D team, technical innovation, market-responsive product development, and feedback integration from global partners. It also reports total R&D engineer experience of 11–20 years, supporting an established innovation function.

Production capacityThe supplier presents itself as a chemical manufacturer and reports two production lines, 21–30 quality-control staff, and fulfillment within 15 working days in both peak and off-peak periods. Its product portfolio and end-to-end commercial supply description support production capability, although total output details are not evaluated here.

Customization capabilityThe supplier explicitly offers customized formulations for specific application challenges and provides formulation optimization, application testing, and troubleshooting. Its process includes sample testing through full-scale commercial supply, indicating support for tailored industrial additive solutions.

Product Q&A

Q:What are the main applications of HPMC?

Construction (tile adhesives, putty powders, mortars), Pharmaceuticals (tablet coatings, vegetarian capsules), Food (thickener E464), Personal Care (toothpaste, shampoo)

Q:How to dissolve HPMC properly?

The most common method: Mix HPMC powder with dry materials (cement/gypsum) first, then add water. This prevents clumping.

Q:Does higher viscosity mean better water retention?

Not necessarily. Once viscosity exceeds 100,000-150,000 mPa s, water retention improvement is limited, but workability suffers (sticky, heavy trowel). Water retention depends more on purity than viscosity.

Q:Why does putty powder crack or lose powder (low strength)?

Usually insufficient HPMC water retention, preventing complete cement hydration. Poor quality ash calcium (lime) or cement could also be the issue. HPMC only provides physical water retention and does not participate in chemical reactions.

Q:What to do if mortar is sticky and heavy to trowel?

The HPMC viscosity is too high. Switch to a medium-low viscosity grade (40,000-70,000 mPa s). It provides sufficient water retention with much smoother workability.
