Manufacturing Process: Redispersible Emulsion Powder The production of redispersible emulsion powder involves highly controlled operations that ensure product consistency, compliance with ISO, ANSI standards, and superior technical performance. Manufacturing Process Flow (VAE-Based) 1. Emulsion Polymerization → Mixing of vinyl acetate, ethylene, & surfactants to form VAE latex emulsion 2. Spray Drying → Emulsion sprayed into hot chamber; water quickly evaporates, powder forms 3. Agglomeration & Collection → Particles agglomerate, then separated/classified by size 4. Anti-caking Treatment → Flow agents (e.g. cellulose ether, silica) added for powder stability 5. Quality Control & Packing → ISO and ANSI standard tests; packed in laminated, moisture-resistant bags [Video: Redispersible powder VAE spray drying - YouTube] Testing & Certification : Each batch passes viscosity, re-dispersibility, and wet abrasion resistance tests according to ISO 14001, EN 12004, ANSI 118.4 , assuring top European/US project compliance. 4.

Most leading RDPs use VAE (vinyl acetate-ethylene), but others employ vinyl acetate homopolymer, EVA, acrylate, or styrene-butadiene—chosen for specific adhesion, flexibility, or water resistance properties. Q2: What is the typical particle size range, and how does it affect performance? 80–150 μm is typical for VAE powders. Finer grade improves redispersion and mortar smoothness while optimizing coverage; coarser grades are used for rough mortars. Q3: Which testing standards are most relevant for RDP quality and installation? ISO 14001 (env.), ISO 9001 (QM), ANSI A118.4 (tile adhesives), EN 12004/EN 14891 (waterproofing/flexural adhesion), ASTM C348 (mortar flexural strength). Q4: How is dosage optimized in different applications? -- Internal wall putty: 1.5–2.5% -- Cementitious tile adhesive: 3–6% -- Flexible waterproof mortars: 5–7% -- EIFS: 2.5–4.5% of dry mix by weight. Q5: Are there special storage or handling requirements? Yes, store sealed container111s dry, under 30°C , avoid moisture, use within 24 months. Opened bags must be resealed. Q6: What industry certifications do SSH Chemical and its partners hold? ISO 14001, ISO 9001, CE, ANSI compliance, product conformances to EN standards, SGS-certified processes; formal partnerships include EPC contractors in Asia, Europe, and N. America.
