Rdp Redispersible Polymer Powder for Tile Adhesive EIFSJune 6th 2023
The product application range of hydroxypropyl methylcellulose includes: masonry mortar, board joint filler, cement-based plaster, gypsum plaster and plaster products, water-based paint and paint remover, tile adhesive, self-leveling floor Due to the wide range of applications such as materials and formed concrete slabs, whether it is used as a binder, stabilizer, or other aspects, it can only be used after it is dissolved.
Application of Putty Powder Hydroxypropyl Methyl Cellulose
1. In the role of putty powder, hydroxypropyl methyl cellulose only plays an auxiliary role and does not participate in any chemical reaction. The putty powder is a chemical reaction when water is added to the wall. Because of the formation of new substances, the putty powder on the wall is removed from the wall and ground into powder to form a new substance. Hydroxypropyl methylcellulose only retains water and assists the better reaction of gray calcium. It does not participate in any reaction by itself.
Putty powder generally has a viscosity of 100,000, but the mortar requires a higher viscosity, which is easy to use. And the most important role of hydroxypropyl methyl cellulose is to retain water, followed by thickening. In putty powder, as long as the water retention is good, the viscosity is lower (70,000-80,000), it is also possible. Of course, the viscosity is higher, and the relative water retention is better. When the viscosity exceeds 100,000, the viscosity has no effect on water retention. Larger, the water-retaining properties of hydroxypropyl methyl prevent it from cracking due to drying too fast, enhancing the strength after hardening.
