Redispersible Polymer Powder (RDP) is a versatile polymer widely used in construction for enhancing adhesion, flexibility, and water resistance. Its key applications include: External Thermal Insulation Systems RDP improves adhesion between insulation boards and mortars, increasing flexibility and preventing cracking caused by temperature changes or stress. It also enhances weather resistance, ensuring the longevity of […]

Following are some of the key factors that may have an impact on HPMC viscosity: 1. Molecular weight: The higher the molecular weight, the higher the viscosity. 2. Degree of substitution: The number and type of substituent groups determine the polymer’s solubility and viscosity. 3. Concentration in solution: The higher the concentration, the thicker the solution. 4. Temperature: The viscosity […]

Chemical Structure: HPMC is made by replacing cellulose’s hydrogen atoms with hydroxypropyl and methyl groups, leading to a non-ionic, stable compound. Water Solubility: It dissolves easily in water, making it ideal for applications requiring stable dispersions or consistent texture. Thermal Gelation: HPMC’s gelation upon heating offers valuable control in pharmaceutical and construction uses. pH Stability: […]

Thermal stability of HPMC and MHEC is affected by their gel temperature. In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that […]

Reduce water loss on concrete surface, preventing cracks and increase scrape area. It is widely used in wall plaster and tile adhesive products In paints, as […]

Enhanced Adhesion: One of the primary advantages of RDP powder is its ability to significantly improve the adhesion properties of cementitious materials. This results in better bonding between different substrates and layers, ensuring the durability and longevity of the construction. Improved Flexibility: RDP powder imparts flexibility to the materials it is added to, allowing them to accommodate […]

Tile Adhesives: RDP powder is widely used in tile adhesives to improve their flexibility, adhesion strength, and workability. The polymer enhances the bond between tiles and substrates, allowing for better stress distribution and reducing the likelihood of tile detachment under thermal or mechanical stress. Plasters and Renders: In plasters and renders, RDP powder improves adhesion […]
