HPMC is used for putty layer. It was originally used in auxiliary materials in the medical industry. Later, it was applied to the construction industry in a unique way. In the field of wall treatment, HPMC material 80-100 mesh ultra-fine powder can directly solve the final effect of putty construction.
And after real testing：
the HPMC putty layer can still maintain an operating time of 3 hours at a high temperature of 58℃ in a high temperature environment, and harden within 90 minutes. The water retention rate is as high as 98%, which prevents cracking and wall peeling due to high temperature, and is suitable for large-scale construction.
HPMC is used for putty layer. Even in extremely low and harsh environment of -25℃, it has passed no less than 50 freeze-thaw cycle tests. In the humid climate of Southeast Asia, it is easy to breed mold, but our HPMC used for putty layer can inhibit mold in 95% of the environment. Applying it in the construction of high-rise buildings can effectively reduce 32% of material consumption, achieve high efficiency and reduce economic expenses.
In addition, HPMC is environmentally friendly when used in putty layers. It has a natural biodegradation efficiency of over 85% in 28 days, does not contain harmful substances such as formaldehyde, and reduces carbon emissions from wall treatment by 18%.
