HPMC can be divided into instant type and hot soluble type, instant type products, in cold water quickly dispersed, disappear in the water, at this time the liquid has no viscosity, because HPMC is just dispersed in the water, no real solution.About 2 minutes, the viscosity of the liquid gradually increased, the formation of a transparent viscous colloid.

Hot-soluble products, cold water agglomeration, can be in hot water, quickly dispersed, disappear in the hot water, when the temperature drops to a certain temperature, viscosity slowly appear, until the formation of transparent viscous colloid.

Hot-soluble type can only be used in putty powder and mortar, in the liquid glue and paint, there will be agglomeration phenomenon, can not be used.Instant model, application scope is wide a few, in be putty with child powder and mortar, and in liquid glue and coating, all can use, do not have what taboo.
