FAQ: CP-EWS Inorganic Rheological Additive
Q1: What is Inorganic Rheological Additive CP-EWS and how is it used?
A: CP-EWS is an inorganic modified bentonite designed for use in water-borne systems. It functions as a rheology modifier to improve gel formation, stabilize viscosity, and enhance suspension in paints, coatings, and other aqueous formulations.
Q2: How does CP-EWS differ from CP-EW?
A: Compared to CP-EW, CP-EWS provides stronger thixotropic behavior, better transparency, and more uniform dispersion, making it ideal for formulations that require smooth flow and minimal settling.
Q3: What are the key properties of CP-EWS?
A: CP-EWS is a fine, white powder composed of inorganic modified montmorillonite clay. It has low moisture content (≤10%), bulk density between 0.40–0.60 g/cm³, excellent viscosity in aqueous systems (≥3000 mPa.s at 3%), and a fineness of ≥95% below 74μm.
Q4: What advantages does Inorganic Rheological Additive CP-EWS offer in formulations?
A: CP-EWS quickly forms transparent gels at low concentrations, disperses easily, prevents pigment settling, and provides high thixotropy along with strong anti-sag properties, ensuring consistent performance across a variety of industrial water-borne applications.
Q5: Which applications are suitable for CP-EWS?
A: CP-EWS is widely used in:
- Water-reducible industrial paints and emulsions
- Sealants and adhesives
- Toothpaste, tooth polish, creams, and lotions
- Pigment slurries and blung water
- Ceramics and other water-based industrial products
Q6: How should CP-EWS be incorporated into a formulation?
A: The additive can be added as a powder at 0.2–3.0%. Typical procedure:
- Prepare water (pH 7.0–8.0)
- Disperse CP-EWS at high speed for 20–30 minutes
- Add other additives
- Incorporate pigments and fillers, mix thoroughly
- Introduce the emulsion
- Apply post-correction if necessary
Q7: What is the recommended storage for CP-EWS?
A: CP-EWS has a 2-year shelf life. Store in a cool, dry, and ventilated area to maintain its performance and prevent moisture-related issues.
Q8: How is CP-EWS packaged?
A: The product comes in kraft paper bags with PE liners or multi-wall paper sacks, typically 25 kg or 22.68 kg per bag, with options for customized packaging available.
Q9: Are there safety considerations when handling CP-EWS?
A: Full safety details are available in the Material Safety Data Sheet (MSDS) provided by Zhejiang Camp-Shinning New Material Co., Ltd.. Proper handling and storage are recommended to maintain product integrity and ensure user safety.
