What does hydroxypropyl methylcellulose do?

HPMC is widely used in our daily life. Construction-grade HPMC is the key ingredient for dry mix mortar, tile adhesive, joint filler, wall putty/skim coat, self-leveling floor, and gypsum plaster. Detergent grade HPMC is a perfect dispersant and thickener, to extend product shelf life.

Why is calcium formate used for construction?

Calcium formate significantly increases the growth of calcium alumina in the early stage of cement hydration, accelerates the hydration of C3S and improves the early strength of cement products, but has little effect on the setting time of cement. The physical properties of calcium formate are stable at room temperature and are not easily caked, making it more suitable for use in dry mortar, with good resistance to freezing and thawing and negative temperature construction.

What is hydroxypropyl methylcellulose made from?

HPMC is obtained from natural renewable resources, fine cotton, and wood pulp.

Is hydroxypropyl methylcellulose safe?

HPMC is a safe ingredient to use in construction, pharmaceutical, food additives, and detergent. It’s harmless to humans, as well as our environment.
