In the construction industry, MHEC powder is commonly used in products like tile adhesives, cement-based plasters, and mortars. Here’s how you can use it: 1. Tile Adhesives: – Mixing: Add the required amount of MHEC powder to the dry mix of cement and sand. The typical dosage ranges from 0.1% to 0.5% by weight of the dry […]

The main Redispersible polymer powders currently used in the market are: vinyl acetate vinegar and ethylene copolymer latex powder (VAe/E), ethylene and vinyl chloride and lauric acid ethylene vinegar ternary copolymer latex powder (E/VC/VL), vinyl acetate vinegar and Ethene and higher fatty acid vinyl ester ternary copolymer latex powder (VAe/E/VeoVa), vinyl acetate vinegar and high […]

Redispersible latex powder is a kind of water-based dispersion, which disperses latex particles in water through advanced drying process. Adding redispersible latex powder to the tile adhesive can improve the fluidity, viscosity and ductility of the tile adhesive, making it more suitable for bonding various materials. On the one hand, redispersible latex powder can provide […]

Efficient Construction Processes: The improved workability and extended open time provided by HPMC contribute to more efficient construction processes. This is particularly beneficial in large-scale projects where precise application and flexibility during construction are essential. Sustainability and Environmental Considerations: Derived from renewable resources, HPMC aligns with the growing emphasis on sustainable construction practices. Its biodegradability […]

Enhanced Workability and Water Retention: HPMC’s exceptional water retention capacity is a game-changer in construction materials. By forming a film around cement particles, it extends workability, allowing for more precise application and finishing in applications such as mortar and plaster. Improved Adhesion and Cohesion: The role of HPMC in promoting adhesion cannot be overstated. Its […]

Redispersible polymer powder (RDP) is a copolymer of vinyl acetate and ethylene that is dispersed in water and then spray-dried to obtain a free-flowing powder. When added to dry mortar formulations, RDP acts as a crucial binder, enhancing several key properties: Adhesion: RDP improves the adhesion of dry mortar to various substrates, including concrete, masonry, and […]

Enhanced Adhesion and Bonding Strength Redispersible Polymer Powder significantly improves the bond between cement-based materials and various substrates like concrete, plaster, or tiles, ensuring a more durable and stable construction. Increased Flexibility and Crack Resistance The polymer enhances the flexibility of mortars, reducing the risk of cracks and fractures due to structural movement or environmental […]

Reason: The water temperature fluctuated greatly during dissolution, resulting in uneven dissolution of HPMC. Insufficient stirring time or too short resting time, HPMC is not completely dissolved. HPMC batch differences or improper storage conditions affect viscosity stability. Solution: Maintain a constant water temperature during the dissolution process, stir and leave it for enough time (usually […]

HPMC is very sensitive to temperature and exhibits significant differences in dissolution characteristics at different temperatures. Therefore, it is necessary to control the water temperature to prevent sudden changes in viscosity or incomplete dissolution.HPMC usually disperses better in cold water, while it tends to swell or agglomerate in hot water. Solution: Avoid using high temperature […]
