Product Overview
High Whiteness Nano Calcium Carbonate, CAS 471-34-1, is high-performance extender pigment designed for powder coatings.Manufactured with strict particle size control technology, this product features outstanding whiteness and favorable thermal stability to adapt to the high-temperature extrusion and curing procedures of powder coatings. It disperses uniformly in polyester, epoxy and hybrid resin systems. Incorporated into powder coating formulas, it upgrades hiding power, surface smoothness and mechanical properties of coating films. In addition, it optimizes melt flow during production. It can partially replace titanium dioxide to lower raw material expenses while keeping stable finished coating quality.
Product Properties
This product is bright white nano powder with narrow particle size distribution. It boasts superior whiteness and low impurity content. The material maintains stable physical and chemical properties under conventional powder coating processing temperatures without discoloration. It has good compatibility with curing agents, leveling agents, pigments and other powder coating additives, and will not trigger unwanted side reactions in the formula.
Core Advantages
High whiteness performance. Effectively promote the hiding power of coating films, reduce the dosage of titanium dioxide and save formulation cost.Excellent thermal stability. No yellowing or discoloration during extrusion and high-temperature curing.Good dispersion in resin matrix. Prevent surface defects such as particles and pinholes on coated workpieces.Improve coating film performance. Enhance hardness, impact resistance and surface flatness after curing.Optimize processing characteristics. Adjust melt fluidity and help obtain uniform coating surface during electrostatic spraying.
Main Applications
This high whiteness nano calcium carbonate is widely used as extender pigment for various powder coatings. Typical applications include epoxy powder coatings, polyester powder coatings, hybrid powder coatings, outdoor architectural powder coatings, hardware anti-corrosion powder coatings and household appliance surface coatings.
Usage Guidance
Add nano calcium carbonate together with resin, pigment and other raw materials at the premixing stage.
