There are several types of hydroxypropyl methyl cellulose HPMC. What is the difference between their uses?

1. Hydroxypropyl methylcellulose HPMC can be divided into instant type and hot-melt type.

1) Instant 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 without real dissolution. In about 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid.

2) Hot-melt HPMC, when it meets cold water, it can be quickly dispersed 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.

2. Different uses of hydroxypropyl methylcellulose HPMC instant type and hot melt type:

   Hot-melt HPMC can only be used in putty powder and mortar. In liquid glue and paint, there will be clumping and cannot be used. Instant HPMC has a wider range of applications. It can be used in putty powder and mortar, as well as in liquid glue and paint, and there is no contraindication.
