Overview of RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS
RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS is chemical compounds added to concrete mixtures to improve various properties of the material, som for eksempel brukbarhet, styrke, varighet, og herdetid. Disse tilsetningsstoffene inkluderer myknere, retardere, akseleratorer, vanntettingsmidler, og luftinndragende midler, hver utformet for å møte spesifikke behov i betongproduksjon. Betongtilsetningsstoffer er ofte brukt i både nærings- og boligbygging, samt i produksjon av ferdig- og ferdigbetong. Ved å forbedre ytelsen og kvaliteten til betong, disse tilsetningsstoffene bidrar til å forbedre den generelle effektiviteten til byggeprosjekter samtidig som de sikrer holdbarheten og levetiden til den ferdige strukturen. De er enkle å inkorporere i blandingen og gir kostnadseffektive løsninger for optimalisering av betongegenskaper i et bredt spekter av bruksområder.
Characteristics of RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS
Forbedret styrke: Betongtilsetningsstoffer kan øke trykkfastheten til betong betydelig, gjør den mer motstandsdyktig mot press og stress. Dette sikrer lang levetid og holdbarhet til strukturer, reduserer sannsynligheten for sprekkdannelse eller feil.


Specification of RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS
RDP Redispersible Polymer Admixture for EIFS
Hva det er
This item is a redispersible polymer powder made for use in cement-based exterior insulation ending up systems (EIFS). Når det kombineres med vann, it forms an adaptable film that bonds well with concrete and other building products. It improves the performance of( EIFS) base and finish coats.
Hemmelige fordeler
Mye bedre vedheft: The admixture helps the covering stick firmly to insulation boards, murverk, og andre underlag. This reduces the danger of delamination or fracturing gradually.
Vannmotstand: It lowers water absorption while still permitting vapor to pass through. This keeps walls dry without capturing moisture inside.
Flexibility and strength: The polymer includes elasticity to the cement matrix. This lets the system manage small movements triggered by temperature adjustments or architectural changes without breaking.
Gjennomførbarhet: It makes the mix easier to apply by hand or machine. The material spreads efficiently and holds its shape after application.
Nøyaktig hvordan du skal bruke
Add the RDP powder directly right into dry cement, sand, og diverse andre helt tørre ingredienser. Bland grundig før du inkluderer vann. Normal dosering varianter fra 2% til 6% etter vekt av fullstendige tørre faste stoffer, depending on the preferred performance. Constantly adhere to the producer’s instructions for your particular EIFS solution. Oppbevar pulveret kjølig, helt tørt område vekk fra fuktighet. Hold posene forseglet når de ikke brukes.
Tekniske funksjoner
– Se: frittflytende hvitt pulver
– Minimum filmdannende temperatur: omkring 5 °C (41 °F).
– Gjentagende fuktighet: mye mindre enn 1%.
– Askeinnhold: ca 10– 15%.

Applications of RDP Redispersible Polymer Admixture in Cement-Based EIFS
Sterkere, Extra Adaptable Surfaces
RDP redispersible polymer admixture enhances the efficiency of cement-based outside insulation completing systems (EIFS). When blended into base coats and coating renders, it develops an adaptable polymer movie after drying. This movie binds cement fragments together much more securely. Som et resultat, the layer comes to be tougher and much less likely to crack under stress or temperature level adjustments.
Better Bond to Insulation Boards
One essential advantage is stronger bonding to insulation boards like EPS or mineral wool. Uten RDP, concrete alone may not stick well to these smooth or low-absorption surface areas. The polymer helps the mortar hold securely, decreasing the danger of delamination or detachment gradually.
Økt vannmotstand
Water can harm EIFS if it leaks via little voids. RDP fills pores in the concrete matrix and produces a water-repellent obstacle. This keeps wetness out while still permitting vapor to leave– vital for protecting against mold and mildew and structural degeneration behind the finish.
Improved Workability and Longevity
Specialists locate RDP-modified mortars simpler to spread out and trowel. The mix stays practical longer and sticks far better to vertical surfaces. Etter herding, the surface resists influence, slitasje, and weathering much better than plain cement provide. This suggests fewer repair services and longer life span.
Regular Performance in Real-World Issues
RDP makes sure reliable results throughout different environments and task sites. It compensates for variations in mixing water, healing conditions, and substrate quality. Contractors obtain consistent toughness, tilpasningsevne, and look set after batch– without added effort or cost.
This admixture is currently conventional in high-quality EIFS formulations worldwide. It fulfills modern-day needs for power effectiveness, aesthetic appeals, and long-lasting structure envelope stability– all while utilizing familiar application approaches.

5 FAQs of RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS
Frequently Asked Questions About RDP for EIFS
What is RDP admixture used for in EIFS?
RDP (Redispergerbart polymerpulver) is added to cement-based coatings in Exterior Insulation Finishing Systems. It helps the coating stick better to insulation boards and other surfaces. It also makes the finish more flexible and resistant to cracking.
How does RDP improve weather resistance?
RDP forms a thin polymer film when mixed with water and cement. This film blocks water from entering the system while still letting moisture vapor escape. Som et resultat, the wall stays dry and protected from rain, vind, og temperaturendringer.
Does RDP affect workability of the mortar?
Ja. RDP gjør mørtelen jevnere og lettere å spre. It improves adhesion during application and reduces sagging on vertical surfaces. Workers find it simpler to achieve an even finish without extra effort.
Can RDP reduce cracking in EIFS finishes?
Det kan det. The polymer in RDP adds flexibility to the rigid cement matrix. This allows the coating to handle small movements caused by thermal expansion or building settling. Fewer cracks mean longer-lasting protection and better appearance.
Is RDP compatible with common EIFS materials?
Ja. RDP works well with expanded polystyrene (EPS), mineralull, and standard cementitious basecoats. It bonds strongly to these substrates and does not interfere with other additives like cellulose ethers or defoamers. Følg alltid produsentens blandingsinstruksjoner for best resultat.
