HPMC aqua retention
HPMC aqua retention is a non-ionic cellulose ether. In cement mortar and gypsum-based slurry, it mainly plays a role of water retention and thickening, which can effectively improve the adhesion and sag resistance of the slurry. It is an indispensable additive in mortar and paste. HPMC aqua retention produced by Milestone Industrial Co. Ltd. has high purity and good quality. It has excellent water retention and thickening properties when used in mortar and gypsum. It is the first choice for cellulose ethers in your construction industry.

Et moles aquarum quae retinere posse affici HPMCwater retentione tempore
1) Since air temperature, wind pressure and other factors will affect the volatilization rate of water in cement mortar and gypsum-based products, there are some differences in the water retention effect of the same amount of HPMC aqua retention in different seasons.
II) in diversis temporibus, in eumdem effectum retention aqua slurry potest esse adaequatum per augmentum et decrementum moles propria HPMC waterretention in constructione. Gypsum in mortarium aquam promovere showdifferent retentio.

Et perficientur res in propria est ut sequitur:
If you want to achieve the water retention effect during the high temperature summer construction, you need to add high-quality HPMC water retention in sufficient quantities according to the formula, so that the water will not lose too fast during the operation; if you do not add high-quality HPMC aqua retention, the high temperature The operation will have quality problems such as insufficient hydration, reduced strength, cracking, hollowing and falling off caused by excessive drying, and it will also increase the difficulty of construction for workers.
If under non-summer and non-high temperature conditions, as the temperature drops, the amount of HPMC aqua retention can be gradually reduced, so that the same water retention effect can be achieved.
