Redispersible latex powder improves the crack resistance of putty in the following ways
January 22nd 2025
The chemistry of RDP revolves around the polymerization of monomers to form stable polymer dispersions, which are later spray-dried to obtain the powder form. Key factors influencing the properties of RDPinclude:
Polymer Composition: Different polymers offer varying properties such as flexibility, adhesion, and water resistance. For instance, VAE-based RPPs are renowned for their excellent adhesion to various substrates.
Crosslinking Agents: Crosslinking agents can enhance the water resistance and mechanical strength of RPP. Common crosslinkers include polyfunctional aziridines and di-isocyanates.
Additives: Additives like dispersants, surfactants, and plasticizers are often incorporated to improve dispersion stability, flow properties, and flexibility of RDPformulations.
