Re-Dispersible Emulsion Powder (RDP)
Description
Overview
Re-dispersible emulsion powder (RDP), polymer emulsion by adding protective colloid and other substances, spray dried, water as a dispersion medium can be re-formed emulsion, polymer powder with redispersibility. It has high flexibility, high weather resistance and high adhesion to various substrates. It is an important additive in dry mortar, which can improve the elasticity, bending strength and bending strength of building materials, reduce shrinkage and effectively prevent cracking.

Product Application
Mortar
Through polymer film formation and three-dimensional bridging structure, Re-dispersible Emulsion Powder upgrades brittle cement mortar into a flexible composite material. Its core value lies in enhanced bonding (especially for difficult-to-bond substrates), crack resistance and weather resistance (elastic buffering + waterproof and frost resistance) and construction optimization (extended open time + improved fluidity).
Tile Bonding Mortar
Re-dispersible Emulsion Powder forms a composite structure of "rigid skeleton + flexible network" in the mortar, improving the overall performance through the triple mechanisms of film formation and bridging, pore filling and densification, and cohesion enhancement.
Tile Sealant
Through the triple mechanisms of film-forming bridging, pore filling and cohesive reinforcement, re-dispersible emulsion powder upgrades traditional rigid cement-based materials into a modern bonding system that is both rigid and flexible. It has the characteristics of safety, durability, construction friendliness and environmental adaptability.
Interior and Exterior Wall Putty
Re-dispersible Emulsion Powder in putty solves the pain points of traditional cement-based putty such as brittle cracking, powder loss, and water seepage through the triple mechanism of "bonding enhancement-flexible buffering-pore blocking". For exterior wall applications, high addition (1.0%-1.5%) is used to achieve weather resistance protection; for interior wall applications, low-cost trace addition (0.4%-0.6%) is used to improve construction performance and environmental protection.
