HPMC voor stopverf
HPMC voor stopverf mainly increases the water retention performance of internal and external wall construction, improves its hydration and opening efficiency, makes the surface of the putty fully hardened and smooth, and the thickening effect improves the adhesion between it and the wall. High water retention, and prolongs the working time of the mortar. And produce high mechanical strength during solidification.

The water retention of HPMC voor stopverf in putty powder. The water retention of putty powder refers to the ability of putty powder to retain and lock moisture:
l The higher the viscosity of HPMC voor stopverf, the better the water retention. Since the cellulose structure contains hydroxyl and ether bonds, the oxygen atoms on the hydroxyl and ether bond groups associate with water molecules to form hydrogen bonds, so that free water becomes bound water, which entangles the water and plays a role of water retention.
l The finer the particles of HPMC voor stopverf, the better the water retention. The surface of the coarse-grained cellulose will dissolve immediately after contact with water and form a gel phenomenon. The mortar wraps the material to prevent the water molecules from continuing to penetrate, and sometimes it is not evenly dispersed and dissolved after long-term stirring, forming a turbid flocculent solution or agglomerate. The fine particles are dispersed and dissolved immediately after contacting with water to form a uniform viscosity.
HPMC voor stopverf promotes the water retention in the putty powder, thereby making the putty powder more stable in wall putty applications.
