HPMC

Hydroxypropyl methylcellulose(INN  name:Hypromellose),also abbreviated  as HPMC,is a variety of non-ionic cellulose mixed ethers.It is a semi synthetic,inactive,viscoelastic  polymer.HPMC is widely used in industries such as building materials,coatings,synthetic resins,ceramics,pharmaceuticals,food,textiles,agriculture,cosmetics,tobacco,etc.HPMC  can be divided into building grade,food grade,and pharmaceutical grade according to its purpose.At present,most of the domestically produced products are of construction  grade.In the construction grade,a large amount of putty powder is used,about 90%of which is used for putty powder,and the rest is used for cement mortar and glue.

Main applications

It has been widely used as exterior wall coatings,adhesives,surfactants,colloid protectants,dispersants,emulsifiers,and dispersant stabilizers.

Enhance water retention,improve the phenomenon of poor hardening and cracking caused by excessive block drying and insufficient water in cement and gypsum building materials; Increased the plasticity of mortar,improved the industrial performance of construction coating,and improved work efficiency

HEC

Hydroxyethylcellulose(HEC)is a white or light yellow,odorless,non-toxic fibrous or powdered solid prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol),belonging to the non-ionic soluble cellulose ether class.Due to its excellent properties of thickening,suspension,dispersion, emulsification,adhesion,film-forming,moisture protection,and providing protective colloids,HEC has been widely used as exterior wall coatings,adhesives,surfactants,colloid protectors,dispersants,emulsifiers,and dispersion stabilizers.

Stable performance: After adding thickeners,it is easy to disperse without flocculation or particle formation,    

Not affecting product quality: Adding it will not cause the product to lose its original performance,and will not cause discoloration,viscosity reduction,and other phenomena

Good aesthetics: No pinholes,spots,or fisheyes,good aesthetics,increasing customer trust
