Hydroxypropyl methyl cellulose HPMC mainly has three kinds of viscosity, HPMC-100000, HPMC-150000, HPMC-200000 viscosity, in general, the production of inner and outer wall putty powder commonly used 100000 viscosity of hydroxypropyl methyl cellulose,

Hydroxypropyl methyl cellulose HPMC as a common building material, in the construction industry is more important, usually hydroxypropyl methyl cellulose main role?

Hydroxypropyl methyl cellulose (HPMC) is an odorless, tasteless, non-toxic white powder. The main raw materials of hydroxypropyl methyl cellulose (HPMC) are refined cotton, chloromethane, propylene oxide and other raw materials and chemicals.

HPMC is a non-ionic hydroxypropyl methyl cellulose. It is the most commonly used water retaining agent in cement/mortar applications. It is less expensive than other types of cellulose ethers and is widely used in dry mortars.

HPMC can be tailored to the viscosity and gel time required to improve the quality of your product. Increase the viscosity of the product system to achieve the desired physical properties, change the product flow to achieve the desired appearance, increase product solids content to reduce material cost, and prevent paint sagging and ensure mechanical properties and stability.

The application of RDP to mortar is actually a modification of ordinary mortar, also known as polymer modified cement mortar. Through polymer modification, the weaknesses of traditional cement mortar such as brittleness and high modulus of elasticity are improved; giving the cement mortar better flexibility and tensile bond strength to resist or retard the generation of cracks in cement mortar

The water retention of hydroxypropyl methyl cellulose products will be affected by the following four reasons, as detailed below, for reference only.

Neutral Putty:

Depowder: insufficient cementitious material, insufficient cellulose water retention, low calcium content of heavy calcium

Wall putty(Skim Coat) is a kind of decorative materials to make wall surface smooth, it can be used in exterior and interior wall decoration. SLEOCHEM HPMC plays an essential role in wall putty(skim coat) to improve the key properties like water retention, open time, crack resistance, workability, etc.
