Hydroxypropyl methyl cellulose (HPMC) is widely used in building materials, and it has the following characteristics for external wall insulation:
Choosing the appropriate cellulose can provide the highest bond strength mortar;
In the application method, the mortar added with cellulose has a certain consistency and does not sag. Make the mortar work continuously in the application;
It is easy to heat the wall, easy to paste, so that other additional materials can achieve the best effect;
Adding hydroxypropyl methyl cellulose during construction can reduce the air inlet of the mortar and reduce the water absorption rate.
