Hydroxypropyl methyl cellulose (HPMC)
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additivesFeature
• High water retention
• Good workability
• Overall good performance
• Very good open time
• Thermal stability improved
• Less retardation of cement hydration
• Excellent slip resistance
Characteristic of HPMC in constructions
Hydroxypropyl methylcellulose can improve the homogeneity of cement-based tile adhesive,which permits an easier painting of the mortar .Thus the working efficiency is improved and the resistance to sagging is enhanced.
Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.
Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.
Increased water demand: increased open time, expanded spry area and more economical formulation.
Easier spreading and improved sagging resistance due to improved consistency.
