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.
Hydroxypropyl methylcellulose HPMC is made of highly pure cotton cellulose as raw material, which is specially etherified under alkaline conditions. Among them, it is divided into two types: instant HPMC and hot melt HPMC. Today we mainly talk about instant HPMC. Instant HPMC, also called cold water instant HPMC. It is surface treated with glyoxal and quickly dispersed in cold water. Adding it to normal temperature water or cold water will quickly decompose, but it is not really dissolved. The viscosity is up, and it is dissolved. It is commonly used in construction glue and daily necessities.
What you need to pay attention to when using instant HPMC are:
1. The PH value of water: the lower the PH, the longer the time. It is recommended to add in neutral water, and then adjust the PH value to alkaline will quickly form a consistency, of course, in actual use generally do not need special adjustment, most other materials will automatically Brings up the PH value.
2. Even after adding the material, it must be stirred, otherwise it will be layered and thick.
4. If the moisture is too high, the content is too low, which is equivalent to reducing the solution concentration.
