Frequently Asked Questions
Q
How to select proper viscosity of HPMC?
100,000‑200,000 mPa·s is recommended for tile adhesive & wall putty. 400‑5,000 mPa·s is suitable for self‑leveling compounds. Samples are available for formulation test.
Q
Can this HPMC work under 5℃ winter construction?
Yes. It delivers stable performance at low temperature and prevents premature drying of mortar.
Q
What are the storage requirements and shelf‑life?
It has a 24‑month shelf‑life under cool dry condition below 30℃. Please keep the package sealed after opening.
Q
What is the raw material source of GinShiCel HPMC?
It is produced from 100% Xinjiang high‑quality refined cotton via advanced etherification technology, featuring a triple sieving process for no agglomeration and fast cold‑water dissolution.
