Kingcel HPMC for dry mix mortar
Kingcel HPMC is the most important addive for all kinds of dry mix mortars (cement based tile adhesive, white cement based skim coat/wall putty, gypsum plaster, masonry mortar, cement plaster, selveling leveling mortar etc.), although the dosage is very low (normally from 0.1-0.5%).
The main functions of Kingcel HPMC:
Water retention: Chemical reaction (hydration) between water and cement/gypsum will cause crystals to grow and wrap around the mix components. During the early stages of cure , there must be enough water to maintain the hydration process otherwise the cement/gypsum will harden promptly. KingCel HPMC can reduce the water loss, allow the crystal structure to keep growing and building strength during the critical early curing stage.
Lubrication effect: When the dry mix mortars are mixed with water, air are entrained and which gives easy handling, better workability.
Thickening effect: KingCel HPMC is used as a thickening agent in building applications as it can prevent segregation and improve the cohesion of the components.
