RDP/VAE, redispersible polymer powder. It is made of vinyl acetate/ethylene copolymer emulsion (EVA emulsion) modified by adding water-soluble protective colloid (polyvinyl alcohol usually PVA), and then spray-dried. Using water as a medium, it can be re-formed into an emulsion with redispersible powder.

HPMC, the full name of hydroxypropyl methylcellulose, also known as hypromellose.

Choose the right specifications of cellulose ether(HPMC/MHEC), the workability of plaster could be improved significantly. HPMC / MHEC could provide a good consistency. Make the plaster easy to scrape on the wall, increase the efficiency.

As we all know, cement, gypsum or lime based plaster is one of the main applications of cellulose ether. In comparison, HPMC is widely famous in function materials. Today we will study more about the application of SLEOCHEM cellulose ether for wall plaster.

Phenomenon: After the construction is completed and dried, the powder will fall off when touched by hand. In building materials, the addition amount of HPMC for wall putty is very low, only 0.1%-1%, but it plays an irreplaceable role and can significantly improve the water retention,

Construction mortars include plastering mortar, masonry mortar, tile adhesive, grout, and floor mortar. When applied to the base surface with high water absorption, good water retention is very important for building mortar.

SLEOCHEM dispersible polymer powder (RDP) forms a polymer network in the mortar product, connecting the tiles and the mortar together through intermolecular forces, and even if the tiles are denser, they can be firmly attached to the mortar.

The water retention of hydroxypropyl methyl cellulose decreases with the increase of temperature, and the fineness also requires 20% to 60% of the particle size to be less than 63um, and the surface immediately dissolves to form a gel to wrap the material to prevent water molecules continue to penetrate,

The term hydroxypropyl methyl cellulose(HPMC) is not only a bit confusing to pronounce, it’s hard to understand its ingredients and uses as mortar. About how it is formed, the Factory uses plain language for everyone explains.
