6. How to check quality?

Whiteness, fineness (finer = better), solution clarity (clearer = better), specific gravity (higher = better water retention).

7. Why does putty have bubbles?

Too much water or applying second coat on a wet base.

8. Why does putty powder dust off?

Mainly poor-quality lime (ash calcium); poor HPMC water retention is secondary.

9. Does HPMC participate in chemical reactions?

No. Physical role only (water retention/thickening/lubrication).

Cool, dry, sealed, moisture-proof. Aqueous solutions need preservative.

Product Q&A

Q:1. How to choose the right grade?

Putty powder : 100,000 Mortar & tile adhesive : 150,000+ Film coating : low viscosity (3-15) Controlled-release tablets : high viscosity (4,000-100,000)

Q:2. HPMC 100,000, What does the number mean?

Viscosity of a 2% solution at 20 degree (mPa.s). Higher number = thicker.

Q:3. What's the difference between "Instant" and "Hot-Soluble"?

Instant: disperses in cold water, viscosity releases gradually Hot-Soluble: disperses in hot water, dissolves upon cooling

Q:4. Can I add directly to hot water?

No. It will form hard lumps.

Q:5. What affects viscosity?

Temperature ( low when hot, high when cold), concentration (higher = thicker), pH (stable 3-11), additives (test compatibility).
