Redispersible polymer powder RDP building mortar additive
Redispersible polymer powder (RDP) is a water-soluble polymer powder that is used as an additive in building mortars. It is made by spray-drying a polymer emulsion, which results in a powder with a high surface area and good dispersibility in water. RDP imparts a number of beneficial properties to mortars, including:
- Increased workability: RDP makes mortars easier to mix and apply, even at low temperatures.
- Improved water retention: RDP helps to prevent mortars from drying out too quickly, which can lead to cracking and shrinkage.
- Enhanced bonding strength: RDP improves the bond strength between mortar and substrate, which can help to prevent detachment.
- Increased flexibility: RDP makes mortars more flexible, which can help to resist cracking and damage from thermal expansion and contraction.
- Better weather resistance: RDP helps to make mortars more resistant to weathering, such as rain, snow, and UV radiation.
RDP is a versatile additive that can be used in a variety of building mortars, including:
- Tile adhesives: RDP helps to improve the adhesion of tile adhesives to substrates, such as concrete, brick, and wood.
- Plasters: RDP helps to improve the workability, water retention, and bonding strength of plasters.
- Self-leveling mortars: RDP helps to improve the flowability and leveling properties of self-leveling mortars.
- Crack fillers: RDP helps to improve the crack-filling properties of crack fillers.
- Thermal insulation mortars: RDP helps to improve the thermal insulation properties of thermal insulation mortars.
RDP is a safe and effective additive that can be used to improve the performance of building mortars. It is a versatile product that can be used in a variety of applications, making it a valuable tool for builders and contractors.
