Redispersible polymer powder has very outstanding bonding strength, improves the flexibility of the mortar and has a longer open time, imparts excellent alkali resistance to the mortar, and improves the adhesion/adhesiveness, flexural strength, water resistance, plasticity, and resistance of the mortar. In addition to abrasion performance and workability, redispersible powder has stronger flexibility in the flexible anti-cracking mortar.
Redispersible Polymer Powder RDP Powder is water-soluble dispersible powder, such as ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc., with polyvinyl alcohol as a protective colloid. Their application range is wide because re-dispersible latex powders have high bonding ability and unique properties, such as water resistance, construction, heat insulation, etc.

Package and transportation
Package of Redispersible Polymer Powder RDP Powder
Paper-plastic compound square bottom valve bag, 25kg/bag. If special specification packaging is needed, it can be customized in advance.
Storage of Redispersible Polymer Powder RDP Powder
Redispersible polymer powder should be stored in a cool and dry place. The recommended period of use is six months.
Please use re-dispersible powder as early as possible when used in summer.
If stored in a hot and humid place, re-dispersible powder will increase the chance of agglomeration.
Please use re-dispersible powder as much as possible after opening the bag.
Q1
What effect does the amount of redispersible latex powder have on the performance of concrete?
Answer:
The amount of redispersible latex powder added has a significant impact on the performance of concrete. An appropriate amount of redispersible latex powder can improve the strength, durability and crack resistance of concrete. However, excessive use may cause the concrete to become brittle or lose its performance benefits.
Q2
How to choose suitable redispersible latex powder?
Answer:
Selecting a suitable redispersible latex powder requires considering factors such as project requirements, concrete type, and environmental conditions. Redispersible latex powder should be selected that has good compatibility with the concrete materials used, stable performance, and meets environmental protection requirements.
Q3
Is redispersible latex powder compatible with other additives?
Answer:
When choosing to use other additives, testing and verification should be conducted first to ensure compatibility and synergy between the redispersible latex powder and other additives. Avoid performance degradation or material deterioration due to chemical reactions.
Q4
Does concrete using redispersible latex powder require special curing?
Concrete using redispersible latex powder should be properly cured after construction to meet its performance requirements. Appropriate maintenance measures, such as covering, sprinkling, etc., should be taken according to the project situation and environmental conditions to ensure the quality and durability of the concrete.
Q5
How to deal with the impact of redispersible latex powder on the human body?
Answer:
When using redispersible latex powder, appropriate protective measures should be taken, such as wearing masks, gloves, etc. If it accidentally comes into contact with skin or eyes, rinse immediately with clean water and seek medical advice promptly. At the same time, long-term inhalation of dust or gas released from redispersible latex powder should be avoided.
Q6
What is the long-term performance of redispersible latex powder in concrete?
Answer:
Redispersible latex powder has stable long-term performance in concrete. After a period of use and environmental erosion, redispersible latex powder can maintain its performance without degradation, thereby ensuring the long-term stability of concrete structures.
