Hypromellose, also commonly known as hydroxypropyl methycellulose (HPMC) is a coating agent and film-former used as an inactive ingredient in the pharmaceutical industry. It has also been used as a rate-controlling polymer for sustained-release dose forms.
Hydroxypropyl Methyl Cellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic,detergent,paints,as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer requirements. After modified and surface treatment, we can get the goods which is dispersed in water quickly, lengthen open time, anti-sagging, etc.
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
How to protect the finished product of gypsum-based self-leveling mortar?The windows should be closed before the construction work, and all the doors should be closed after the construction work is completed. Pay attention to moisturizing and maintenance within 24 hours after the completion of const
HPMC without surface treatment do not dissolve in hot water above 85, but can swell and disperse in hot water. Usually, the following methods are used:1.Take about 1/5-1/3 of the required amount of hot water, stir to completely swell the added product, and then add the remaining part of the water, w
