Construction grade HPMC & HEMC in building materials
September 18th 2024
Wall putty is a building material used to repair and smooth walls. It is usually mixed with raw materials such as gypsum, cement, lime, fillers and additives. Its main function is to fill in the unevenness of the wall surface, repair cracks and defects in the wall, and make the wall smoother and more beautiful. Wall putty plays an important role in construction and decoration, and can improve the overall quality and beauty of the wall.
Modified HPMC (hydroxypropyl methylcellulose) are commonly used wall putty additives, which can improve the performance of wall putty and improve its processability. The main functions include:
Improve strength: HPMC can increase the adhesion and durability of wall putty, making it stronger after construction, improving the compressive strength and durability of the wall, thereby extending the service life of the wall.
Anti-sag: During the wall construction process, wall putty is prone to sagging, that is, the wall putty is too fluid during the painting or smoothing process, resulting in uneven wall surfaces. Adding HPMC can effectively control the fluidity of wall putty, prevent sagging, and make the wall smoother.
In summary, modified HPMC, as an additive to wall putty, can effectively improve the strength and anti-sag performance of wall putty, making wall repair more stable and beautiful.
