Core Features

  • Excellent anti‑sag & anti‑slip: prevent tile slip and mortar sag for vertical application
  • Improved bonding strength: reduce hollowing and falling‑off risk
  • Good workability: better plasticity for higher construction efficiency
  • Wide temperature adaptability: stable performance under 5℃ low‑temperature winter construction
  • Extended open time: support large‑area wet mortar operation
  • High water retention: delay cement hydration for full strength development

Raw Material Source

100% Xinjiang high‑quality refined cotton as raw material. Triple sieving process, no agglomeration, fast cold‑water dissolution.

Frequently Asked Questions

Q: How to select the proper viscosity of HPMC for different projects?
A: Generally, 100,000‑200,000 mPa·s is recommended for tile adhesive & wall putty. For self‑leveling compounds, a lower viscosity of 400‑5,000 mPa·s is ideal. Free samples are available for formulation testing.
Q: Can this HPMC work under 5℃ winter construction conditions?
A: Yes. It offers stable performance at low temperatures, ensuring high water retention to prevent the premature drying and cracking of mortar.
Q: What are the storage guidelines and shelf-life of the product?
A: The product has a 24-month shelf-life when stored under cool, dry conditions below 30℃. Please keep the packaging tightly sealed after opening.
Q: What is the raw material source of GinShiCel HPMC?
A: We use 100% Xinjiang high-quality refined cotton as our raw material. This ensures clean, high-purity cellulose ether with fast cold-water dissolution.
Q: What quality certifications do your products comply with?
A: Our manufacturing processes comply with the ISO9001 Quality Management System, and our products are fully compliant with EU REACH regulations and validated by SGS test reports.
Q: What is the MOQ and delivery lead time for wholesale orders?
A: The MOQ is 1kg for trial samples and 1MT for bulk wholesale orders. The standard lead time is 7 to 15 working days after receiving payment.
