Types Of RDP For Gypsum
The RDP for gypsum produced by our company mainly include the following types:
Redispersible Polymer
RDP is a versatile polymer powder that can be used as an adhesive in building materials.In general cement mortar formulations, the amount of water needed to add ethylene-vinyl acetate copolymer (re-emulsified powder) is about one to five percent by weight of cement.
Construction Chemicals VAE
Redispersible latex powder product is water soluble redispersible powder, divided into ethylene/vinyl acetate copolymer, with polyvinyl alcohol as a protective colloid, spray drying white powder adhesive.
Benefits of RDP For Gypsum
Improve bonding strength
RDP can significantly improve the bonding strength of gypsum-based self-leveling. Gypsum-based self-leveling requires good bonding properties during the construction process to ensure that it can adhere firmly to the surface of the substrate. The polymer film formed by RDP after drying has high adhesion, which can effectively enhance the bonding strength between the gypsum-based self-leveling and the substrate, thereby reducing the risk of cracking and peeling.
Enhance flexural strength and compressive strength
Gypsum-based self-leveling materials should have certain mechanical strength after curing to withstand the load during subsequent construction and use. The introduction of RDP can effectively improve the flexural strength and compressive strength of the material. The reason is that the polymer network structure formed by RDP inside the material can improve the overall toughness of the material, disperse stress, and prevent the expansion of cracks.
Improve water resistance and moisture resistance
Traditional gypsum-based materials have poor water resistance and are prone to softening and strength reduction in humid environments. RDP has good water resistance. It can form a dense polymer film in gypsum-based self-leveling, blocking the penetration of moisture and significantly improving the water resistance and moisture resistance of the material.
Improve construction performance
The application of RDP in gypsum-based self-leveling can also significantly improve its construction performance. RDP can increase the fluidity and lubricity of the material, making it easier to spread and level during the construction process, reducing construction difficulty and time. In addition, RDP can also adjust the working time of materials so that construction personnel have enough time to operate and improve construction efficiency and quality.
Increase crack resistance
Gypsum-based self-leveling is prone to shrinkage cracks during the drying and curing process, which affects the overall effect and service life. By forming a flexible polymer network in the material, RDP can effectively absorb and disperse stress, reduce the formation of shrinkage cracks, and improve the material's crack resistance.
Improve durability
The introduction of RDP can significantly improve the durability of gypsum-based self-leveling. The polymer film formed by RDP has excellent anti-aging properties, can effectively resist the influence of environmental factors such as ultraviolet rays and oxidation, and prolong the service life of the material.
Considerations When Using RDP For Gypsum
Compatibility with Other Materials: It's essential to ensure that RDP is compatible with other components in the formulation to achieve the desired performance.
Optimal Usage Rates: Determining the appropriate amount of RDP to use is crucial, as excessive amounts may lead to issues such as reduced workability or increased cost without significant performance benefits.
Handling Requirements: RDP should be stored in a cool, dry place to prevent moisture absorption, which can affect its performance.
Storage Considerations of RDP For Gypsum
Redispersible polymer powder should be stored in cool and dry environment. It is recommended to use within 6 months, preferably be used as soon as possible in summer. Storage in high temperature and humidity conditions will increase the risk of caking. Opened containers should be used as soon as possible, if not, should be resealed to prevent ingress of moisture from the air.
Redispersible polymer powder supplied in paper bags should not be stacked. Prolonged heavy pressure may cause caking. Storage under pressure should also be avoided.
