There are different views on the interaction between polyvinyl acetate and cement in aqueous solution. Some scholars think that the modified cement mortar with polyvinyl acetate itself forms polymer film inside and the holes inside mortar are sealed or covered, so its impermeability is improved. Foreign scholars think that the interaction between polymer and Ca(OH)2 … Continue reading
Redispersible Polymer Powder as one of the most important additives in dry-mixed mortar has been widely used in the construction field. Its invention and appearance greatly promoted the popularization and application of dry-mixed mortar. At present the most widely used RD powders are vinyl acetate vinyle-ethylen (VCAE) and vinyl acetate-tert-vinyle carbonate (VEOVA). To improve the … Continue reading
Effect on fresh mortar Extend the work time and improve water retention performance to ensure the hydration of cement and improve workability; Effect on hardened mortar Good adhesion to polystyrene board and other substrates, excellent flexibility and impact resistance, excellent water vapor transmission, good water repellency and weatherability. Traditional bonding materials has a great hidden … Continue reading
The Composition of RDP The RDP is usually a white powder but there are a few other colors. The components of Redispersible Polymer Powder include: Polymer Resin: in the core part of RDP, also the main component of Redispersible Polymer Powder, such as polyvinyl acetate/hexane resin; Additive: It acts as a modified resin together with the … Continue reading
