HPMC (Cellulose ether) is one of the most commonly used additives in dry mortars. It forms a lubricating film on its outer surface, which makes the mortar system more stable and improves the fluidity of the mortar during mixing and the smoothness of the construction. Due to its molecular structure, fibrous cellulose ether does not easily lose water in the mortar and is released gradually over a long period of time, giving it good water retention and workability.
The water retention of cellulose ethers is the most important and basic indicator. Water retention refers to the amount of water retained by a newly mixed mortar on an absorbent substrate, after capillary action.
