RDP (Re-Dispersible Polymer Powder) and HPMC (Hydroxypropyl Methylcellulose) are both commonly used additives in the formulation of skim coats and other construction materials. They serve different but complementary purposes in enhancing the properties of skim coat: RDP (Re-Dispersible Polymer Powder): RDP is a polymer powder obtained by spray-drying a water-based emulsion of polymers. When added […]

Re-dispersible polymer powder (RDP) is a type of polymer that is used in a variety of construction applications, including putty powder for internal and external walls. RDP is made by spray-drying a water-based emulsion of vinyl acetate-ethylene (VAE) copolymer. The resulting powder is free-flowing and can be easily re-dispersed in water to form a stable […]

Use basic properties to qualify its quality 1. Appearance: The appearance should be white free-flowing uniform powder without irritating smell. Possible quality manifestations: abnormal color; impurity; particularly coarse particles; abnormal smell. 2. Dissolution method: Take a small amount of redispersible polymer powder and put it into 5 times the water, stir first and then wait […]
