The instant Hydroxypropyl methylcellulose (HPMC) disperses quickly in cold water and disappears in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and does not really dissolve. In about 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid.
Hot-melt Hydroxypropyl methylcellulose (HPMC), when they come together in cold water, they can quickly disperse in hot water and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until A transparent viscous colloid is formed.
Hot-melt Hydroxypropyl methylcellulose (HPMC) are generally used in putty powder and mortar. The powder mixing method is adopted: the HPMC powder is mixed with a large amount of other powdered materials, thoroughly mixed with a mixer, and then dissolved by adding water, then the HPMC can be dissolved without clumping Cohesion, because each tiny corner contains only a little HPMC powder, which will dissolve immediately when it encounters water.
Instant Hydroxypropyl methylcellulose (HPMC) has a wider range of applications. In addition to putty powder and mortar, it is widely used in daily chemical products such as liquid glue, paint, and detergent.
