Specification of RDP Redispersible Polymer Concrete Admixture for Cement Based Exterior Insulation Finishing System EIFS

RDP Redispersible Polymer Admixture for EIFS

Apa Itu

This item is a redispersible polymer powder made for use in cement-based exterior insulation ending up systems (EIFS). Apabila digabungkan dengan air, it forms an adaptable film that bonds well with concrete and other building products. It improves the performance of( EIFS) base and finish coats.

Faedah Rahsia

Lekatan yang lebih baik: The admixture helps the covering stick firmly to insulation boards, batu, dan substrat lain. This reduces the danger of delamination or fracturing gradually.
Rintangan air: 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.
Kebolehkerjaan: It makes the mix easier to apply by hand or machine. The material spreads efficiently and holds its shape after application.

Tepat cara Menggunakan

Add the RDP powder directly right into dry cement, pasir, dan pelbagai lagi bahan kering sepenuhnya. Campurkan secara meluas sebelum memasukkan air. Varieti dos biasa daripada 2% kepada 6% mengikut berat pepejal kering lengkap, depending on the preferred performance. Constantly adhere to the producer’s instructions for your particular EIFS solution. Simpan serbuk dalam sejuk, kawasan kering sepenuhnya dari kebasahan. Pastikan beg tertutup apabila tidak digunakan.

Ciri-ciri Teknikal

– Tengok: serbuk putih yang mengalir bebas
– Suhu pembentukan filem minimum: sekeliling 5 ° C (41 ° F).
– Kelembapan berulang: much less than 1%.
– Kandungan abu: about 10– 15%.
– Dimensi zarah: goes through a 100-mesh filter.

This admixture satisfies basic needs for external wall systems and supports lasting durability in diverse climate condition.

Applications of RDP Redispersible Polymer Admixture in Cement-Based EIFS

Lebih kuat, 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. Akibatnya, 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. Tanpa 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.

Dipertingkatkan Ketahanan Air

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. Selepas pengawetan, the surface resists influence, melecet, 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, kebolehsuaian, 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 (Serbuk Polimer Boleh Sembur Semula) 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. Akibatnya, the wall stays dry and protected from rain, angin, dan perubahan suhu.

Does RDP affect workability of the mortar?

ya. RDP menjadikan mortar lebih licin dan lebih mudah disebarkan. 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?

Ia boleh. 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?

ya. RDP works well with expanded polystyrene (EPS), bulu mineral, and standard cementitious basecoats. It bonds strongly to these substrates and does not interfere with other additives like cellulose ethers or defoamers. Sentiasa ikut arahan pencampuran pengeluar untuk hasil terbaik.
