HPMC can be divided into instant and hot soluble products. Instant products disperse rapidly in cold water and disappear in water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and does not dissolve. For about two minutes, the liquid slowly becomes more viscous, forming a clear, sticky gel. Hot soluble products, in cold water, can disperse rapidly 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 type can only be used in putty powder and mortar, in liquid glue and paint, there will be conglomeration phenomenon, can not be used. Instant, with a wide range of applications, can be used in putty powder and mortar, as well as liquid glue and paint, with no taboos.
