Hydroxypropyl methyl cellulose, abbreviated as cellulose [HPMC], is made of highly pure cotton cellulose as raw material, and is prepared by special etherification under alkaline conditions. The whole process is completed under automated monitoring and does not contain any Active ingredients such as animal organs and oils.

Cellulose Ether (Cellulose Ether) is made from cellulose through the etherification reaction of one or more etherification agents and dry grinding.

Redispersible polymer powder is mainly used in: internal and external wall putty powder, tile adhesive, tile grout, dry powder interface agent, external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc.

Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based.

Hydroxypropyl methylcellulose HPMC endows wet mortar with excellent viscosity, which can significantly increase the adhesion between wet mortar and the base layer, and improve the anti-sagging performance of mortar. in mortar. The thickening effect of cellulose ether can also increase the homogeneity and anti-dispersion ability of fresh cement-based materials

Product name: hydroxyethyl methyl cellulose HEMC

1. Mix redispersible polymer powder with water in a ratio of 1:5, stir evenly and let it stand for 5 minutes, then observe the sediment on the bottom layer. Generally, the less sediment, the better the quality of RDP.

Control joints are essentially deliberate cracks cut into concrete floors that allow for movement caused by temperature and moisture changes. Put another way, when the concrete does inevitably shrink and crack, it does so on a line (at the bottom of the control joint) instead of randomly across the slab. If left unfilled, control joints can become areas for dirt, debris, and moisture to collect and cause problems.

The general plan for the application effect of HPMC is as follows：
