The performance of HPMC for construction industry in mortar:

a. The embodiment of HPMC for construction industry's flexibility in mortar: In modern buildings, thin-layer materials are used as the base, such as cement fiberboard and gypsum board. However, rigid cement-based materials cannot deform with the deformation of these materials, thus causing the bonding surface to detach. Therefore, only after adding HPMC for construction industry, the adhesive will have sufficient stress absorption capacity.

b. The embodiment of HPMC for construction industry's cohesive force in mortar: Cement can only be bonded on a porous substrate, but this type of substrate is rare in modern buildings. HPMC for construction industry can firmly bond with non-porous substrates, so mortar can still be used on non-traditional materials.

c. The manifestation of HPMC for construction industry's increased opening time of mortar: thin-layer mortar is very easy to lose water and dry due to evaporation or absorption of the base material, resulting in insufficient water for cement to harden. The addition of HPMC for construction industry increases the open time of dry-mixed mortar and also increases its adhesion to various substrates.

d. The waterproofness of HPMC for construction industry mortar: thin layer materials are usually used in decorative construction, such as surface coating. Therefore, there are certain waterproof requirements, which cannot be met by pure cement systems. After joining the HPMC for construction industry, it will have certain waterproofness;

e. The impact resistance of HPMC for construction industry is reflected in the mortar: all rigid systems are prone to impact damage. Adding HPMC for construction industry can greatly reduce such problems.

MST has 20 years of experience in the production of HPMC for construction industry, and can produce products with different viscosities according to customer needs.HPMC for construction industry.
