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.
HPMC hydroxypropyl methylcellulose produced by YIDA can be used as a thickener, dispersant, and stabilizer in construction mortar, tile adhesive,wall putty,gypsum mortar,cement mortar and so on.
YIDA VAE/RDP has good film-forming properties, is easily soluble in water and easy to form emulsions, has strong cohesion, and has strong tensile properties. It can give mortar good fluidity and workability, and effectively improve mortar cohesion and impact resistance. resistance, wear resistance, weather resistance, sealing, impermeability and bond strength.
Polycarboxylate superplasticizer is a chemical admixture for concrete and self-leveling mortar, which can improve the workability of concrete and reduce water consumption.
The defoamer is a powder defoamer for nonionic surfactants used in cement and gypsum-based dry-mixed mortar mixtures. It has the characteristics of easy dispersion, fast defoaming, high stability and strong adaptability.
