Application of HPMC in building materials

Application of HPMC in cement mortar
In the production process of cement mortar, HPMC, as a thickener, water retainer and key component for improving construction performance, should be added in the dry mix production stage of mortar. This ensures that it provides the best water retention when the mortar is used, improves lubricity during construction, and enhances the bonding strength after final curing.

Application of HPMC in gypsum mortar
HPMC is mainly used in gypsum mortar to adjust the speed of hydration and improve construction performance. Similar to cement mortar, HPMC should be added in the dry mix production stage of gypsum mortar to ensure that it exhibits good fluidity and ease of use during construction, while avoiding premature water loss or cracking of the mortar.

Application of HPMC in putty
The main function of HPMC in putty is to improve water retention, extend the open time and improve the smoothness of application. In the production process of putty powder, HPMC should be mixed with other raw materials to ensure that the putty layer can be effectively prevented from drying too quickly during construction, and the construction quality and surface smoothness can be improved.

Application of HPMC in wall coatings
The addition of HPMC to wall coatings can enhance the anti-sagging property of the coating, improve the uniformity of the paint film, and improve the feel when brushing. It should be mixed with other components in the initial stage of the coating formulation to ensure that the coating can maintain stable fluidity and excellent construction performance during production and use.

Application of HPMC in self-leveling flooring
In self-leveling flooring materials, the main function of HPMC is to improve the water retention and fluidity of the material and ensure the uniformity and flatness of the floor. HPMC should be added in the dry mix production stage of self-leveling floor so that the best fluidity and self-leveling effect can be achieved during construction.

Application of HPMC in waterproof coatings
The addition of HPMC in waterproof coatings can improve the water retention and fluidity of the coating during brushing, and ensure the density and waterproof effect of the coating. In the production process of waterproof coatings, HPMC should be mixed with other ingredients to ensure the uniformity and stability of the coating.

The application of HPMC in building materials is crucial, and the correct addition steps can ensure the performance and construction quality of the materials in use. In the production stage of materials such as cement mortar, gypsum mortar, putty, wall coating, self-leveling floor and waterproof coating, the reasonable use of HPMC can significantly improve the construction performance and final effect of the materials.
