High bonding RDP powder for construction additives
1. Redispersible powder, also known as RDP powder, is white powders obtained by spray drying a liquid emulsion composed of VAE polymers. They can be easily dispersed in water to form a stable emulsion.
2. Flexible RDP powder increases elasticity, preventing tiles from falling off or cracking.
Technical Guide
Differences of Flexible vs. Rigid RDP Powder
Redispersible Polymer Powder (RDP) is categorized into Flexible and Rigid types based on its glass transition temperature (Tg) and film-making properties.
1. Flexible RDP powder (lower Tg) forms a highly elastic and resilient polymer film, making it the ultimate solution for applications requiring outstanding crack resistance, waterproofing, and thermal stress absorption—such as exterior wall insulation systems (EIFS) and premium flexible tile adhesives. Conversely,
2. Rigid RDP powder (higher Tg) provides exceptional compressive strength, cohesive bonding, and surface hardness, which is ideal for rigid systems like indoor wall putties, standard tile adhesives, and high-strength self-leveling floors. Choosing the right formulation ensures the perfect balance of durability, structural integrity, and cost-efficiency for your specific construction needs.
Properties
● Excellent flexibility and resilience: The RDP powder maintains good flexibility and resilience even at low temperatures, exhibiting minimal brittleness or cracking.
● Non-toxic and odorless: Meets environmental and safety standards; RDP powders are commonly used in food packaging and everyday consumer products.
● Strong adhesion and compatibility: Due to its inherent polarity and viscosity, RDP powder can adhere firmly to a variety of substrates (such as paper, wood, textiles, metals, and plastics) and are also easily mixed with other polymers.
● Storage and transportation: RDP powder is a powder, but not a liquid, so it is easy to be stored and easy to transport to any other countries.
