The content of redispersible polymer powder
November 25th 2024
The scientific name of white latex is polyvinyl acetate emulsion, which usually refers to the homopolymerization and copolymer emulsion series products with vinyl acetate as monomer; the scientific name of redispersible latex powder is vinyl acetate-ethylene copolymer emulsion, which usually refers to the copolymerization of vinyl acetate-ethylene and The series of products of vinyl acetate-ethylene and other monomer multi-emulsion copolymer emulsions are not the same in production process, product index, performance, use, etc. The appearance of white latex and redispersible latex powder is not much different. At present, the viscosity of redispersible latex powder for conventional domestic use is relatively low, and white latex generally has a much higher viscosity than redispersible latex powder for better workability. In addition, the flexibility of the redispersible latex powder after film formation is better than that of white latex. In addition, the bonding strength of white latex is very strong. Bond the material to be bonded under the required environment and conditions according to the standard process, and make its bonding strength reach the value, and then conduct the destruction experiment along the bonding interface. If the damage is The material to be glued is white latex. The weather resistance of redispersible latex powder is longer than that of white latex. The viscosity of white latex depends on chemical corrosiveness. The viscosity rises quickly. The longer the time, the greater the damage to the wall, and it can be redispersed. The latex powder is physically sticky, and slowly increases viscosity without any damage to the wall. The longer the time, the stronger the stickiness.
