Stability: Solids are flammable and incompatible with strong oxidants.

hpmc viscosity. The viscosity of HPMC also influences the setting time and strength development of cement-based products, making it a crucial additive in the construction industry.
Answer: HPMC cold water instant type is after glyoxal surface treatment, in cold water quickly dispersed, but not the real dissolution, viscosity is dissolved. The hot soluble type has not been surface treated with glyoxal. The amount of glyoxal is large, the dispersion is fast, but the viscosity is slow, the amount is small, the opposite.
HPMC is extensively used in various construction materials, such as cement-based mortars, gypsum-based plasters, tile adhesives, and self-leveling compounds. Its water retention and thickening properties are particularly valuable in these applications.
