The role of HPMC in putty powder

The role of HPMC in putty powder

Original 2021-06-17 13:56:37

HPMC plays three roles in putty powder: thickening, water retention and construction.

1. Thickening: HPMC thickens, suspends, and keeps the solution uniform up and down, and resists sagging.

2. Water retention: It makes the putty powder dry more slowly and assists the reaction of calcium grey under the action of water.

3. Construction: HPMC has a lubricating effect, which allows the putty powder to have a good construction, and does not participate in any chemical reaction, but only plays an auxiliary role. HPMC is only a water retaining agent to assist calcium grey to react better, it does not participate in any reaction itself.
