Gidroksipropil metiltsellyuloza (HPMC) for Plaster Paint

Asosiy turar-joylar

Gidroksipropil metiltsellyuloza (HPMC) oq rang hisoblanadi, odor-free powder used as a crucial additive in gypsum-based paints. Sovuq suvda oson eriydi va shaffof hosil qiladi, yopishqoq vosita. This option helps control the paint’s density and circulation throughout application.

HPMC ish qobiliyatini yaxshilaydi. It makes the paint simpler to spread on wall surfaces without trickling or sagging. The material likewise slows down water loss from the paint. This offers workers more time to smooth and end up the surface before it dries out.

Ishlash imtiyozlari

In plaster paint, HPMC serves as a water retention representative. Excellent water retention keeps the gypsum plaster hydrated long enough to establish appropriately. Usiz, the paint might dry out as well quick. Fast drying out can create vulnerable points, sinishlar, or poor bond to the wall surface.

HPMC additionally boosts bond. It helps the paint stick strongly to different surfaces like concrete, blok, yoki eski gips. This reduces peeling off or flaking after drying out.

The product supplies secure viscosity throughout a series of temperatures. This indicates the paint acts regularly whether applied in summer season warm or cooler indoor problems.

Texnik tafsilotlar

Normal HPMC grades for gypsum paint have a methoxyl material of 19– 30% and a hydroxypropoxyl content of 4– 12%. The thickness normally varies from 4,000 uchun 100,000 mPa · s (da belgilanadi 2% diqqatni suvda 20 ° C). These values can be adjusted based on the details requirements of the paint formula.

HPMC is non-ionic and compatible with the majority of typical additives used in gypsum systems. It does not react with other components, so it will not impact the setup time or final toughness of the plaster.

Store HPMC in an awesome, namlikdan uzoqda butunlay quruq joy. Keep the packaging sealed when not being used to avoid clumping.
