Product Description

RDP (Redispersible Polymer Powder) is produced by spray-drying special water-based emulsion, mostly based on vinyl-acetate-ethylene (VAE), obtaining a free-flowing organic polymer powder. It re-disperses in water and forms a film after water evaporation. This film acts as an organic binder to glue together different substrates, reinforce mortar structure, and provide excellent adhesion.

Frequently Asked Questions

Q1: What is the primary function of RDP in mortar? A: RDP improves adhesion, flexural strength, and workability of dry-mix mortars. It forms a flexible polymer film that reinforces the mortar structure.

Q2: Can I request a sample for testing? A: Yes, we provide free samples for your reference and quality evaluation upon request.

Q3: What are the standard payment terms? A: T/T or L/C at sight are generally accepted. Other payment methods are negotiable depending on order details.

Q4: What is the typical lead time for an order? A: Lab samples usually take 2-3 days. Bulk production typically requires 7-15 days after all details and confirmations are finalized.

Q5: How should RDP be stored to ensure quality? A: It should be stored in a cool, dry environment below 30°C, protected from moisture and high pressure to prevent caking.

Q6: Is customization available for specific viscosity needs? A: Yes, we can customize products according to required viscosity, water retention, and specific gravity as per customer requirements.
