Overview of Redispersible Polymer Powder

Concreteandmore’s Redispersible Polymer Powder (RDP) is a high-performance polymer additive, made of vinyl acetate-ethylene (KAKI) copolymer through spray drying technology. It can be redispersed into stable emulsion when mixed with water, forming a continuous polymer film in cement-based materials. Our RDP effectively solves the problems of poor bond strength, brittleness and low water resistance of concrete and mortar, improves the flexibility, adhesion and durability of materials, and is widely used in various building materials and construction scenarios around the world.

Features of Redispersible Polymer Powder

• Excellent Redispersibility: Can be quickly redispersed into uniform emulsion when mixed with water, tiada aglomerasi, and fully compatible with cement matrix.
• Strong Bond Enhancement: Forms a tough polymer film, significantly improves the bond strength between cement-based materials and substrates (jubin, konkrit, kayu, dll.).
• Good Flexibility & Crack Resistance: Reduces the brittleness of concrete/mortar, enhances toughness, and effectively inhibits the generation and expansion of microcracks.
• Superior Water Resistance & Weather Resistance: The polymer film has good water resistance, impermeability and weather resistance, improving the durability of building materials.
• Keserasian yang Baik: Compatible with HPMC, pengurang air, defoamers and other common concrete admixtures, tiada tindak balas buruk, mudah digunakan.

FAQs of Redispersible Polymer Powder

1.What is the role of RDP in cement-based materials?

It enhances bond strength, flexibility and water resistance, mengurangkan kerapuhan, and prevents cracking and peeling of concrete/mortar.

2.How to use RDP in construction?

Mix RDP powder evenly with cement, pasir dan bahan kering lain terlebih dahulu, kemudian masukkan air dan kacau sebati untuk memastikan serakan seragam.

3.What is the difference between VAE, acrylic and styrene RDP?

VAE RDP has good flexibility; acrylic RDP has strong water resistance; styrene RDP has high bond strength. Choose according to project needs.

4.Will RDP affect the setting time of concrete?

Proper dosage has little effect on setting time; dos yang berlebihan mungkin sedikit melambatkan penetapan, which can be adjusted by controlling the dosage.

5.Adakah anda menyediakan bekalan global dan sokongan teknikal?

ya, we supply RDP worldwide, dengan TDS lengkap dan bimbingan profesional untuk membantu anda memilih model dan dos yang betul.
