RDP Series Industry knowledge

Resin Dispersing Powder (RDP) is a new type of powdered dispersant primarily used to improve the dispersibility and stability of resins in water-based and powder coatings. Due to its high-efficiency dispersion performance, environmental friendliness, and ease of use, RDP is widely used in the coatings, inks, and adhesives industries. This article will provide a detailed introduction to the properties, main uses, application methods, and common issues of RDP.



1. Main Characteristics of RDP
Resin dispersing powder has the following characteristics:
Excellent dispersibility: It can quickly disperse resin particles in water-based systems, improving uniformity.
Environmentally friendly and non-toxic: Non-solvent based, reducing VOC emissions and meeting environmental standards.
Improved rheological properties: Enhances the fluidity and application performance of coatings and inks.
Easy to use: The powder form is easy to store, weigh, and use, requiring no additional solvents.
Strong stability: Maintains stable dispersion under various pH ranges and temperatures.



2. Main Application Areas of RDP
RDP is widely used in various industries, mainly including:

Application Industry Function & Effect
Water-based Coatings Improves resin dispersion, enhances film uniformity, reduces pigment settling, and improves coating smoothness
Printing Inks Enhances pigment dispersion, improves color intensity and printability
Adhesives & Sealants Promotes uniform resin distribution, improves bonding strength and curing consistency
Construction Materials Used in decorative coatings and cement-based coatings to improve workability and surface finish
Other Industrial Applications Acts as a dispersing aid in composites, plastics, and powder coatings for better resin distribution



3. Application Methods and Precautions for RDP
Addition method: RDP can be directly added to the water-based system and stirred evenly; in powder coatings, it can be mixed with the resin powder before dispersion.
Dosage control: Depending on the desired dispersion effect and resin type, the general addition amount is 1% to 5% of the resin weight.
Storage conditions: Should be stored in a dry, cool, and well-ventilated environment, avoiding moisture and high temperatures.
Compatibility: RDP has good compatibility with most water-based resins (such as acrylic resins, polyurethanes, epoxy resins), but its applicability should be tested under extreme acid and alkaline conditions.



4. FAQ (Frequently Asked Questions)
Q1: Can RDP be used in all water-based coatings?
A1: RDP is suitable for most water-based coating systems, such as acrylic, polyurethane, and epoxy resins, but compatibility testing is required in strong acid or strong alkaline environments.

Q2: Will RDP affect the drying time of the coating?
A2: Generally, it will not significantly affect the drying time, but it may slightly improve the flatness of the coating film, resulting in more even surface drying.

Q3: How to prevent RDP from getting damp and clumping? A3: Store in a dry, sealed container and avoid high temperatures. If slight clumping occurs before use, gently stir the powder to disperse it.

Q4: How is the amount of RDP to be added determined?
A4: It is determined based on the type of resin, coating concentration, and dispersion requirements.  A general recommended addition amount is 1% to 5% of the resin weight. The optimal amount can be determined through small-scale testing.

Q5: Is RDP suitable for powder coatings?
A5: Yes, RDP can be mixed with resin powder in powder coatings to improve dispersion and uniformity, and enhance film smoothness.

Q6: Is RDP environmentally friendly?
A6: RDP is a non-solvent powder dispersant with low VOC emissions, meeting environmental requirements and suitable for green coatings and environmentally friendly adhesives.
