calcium carbonate nanoparticles,
nano precipitated calcium carbonate
Wholesale chemical filler nano calcium carbonate white powder
Nano Calcium Carbonate (CCR-900)
CCR900 special for Sealants and Adhesives ,Features and Advantage:
1.Uniform crystal shap and size ,high activation,good miscibility with organosilicone,Easy dispersion and processing, making silicon adhesives better mechanical property and weathering performance .
2.Low water,approximate neutral and good chemical stability. making polyurethane adhesive ,epoxy glue and MS sealants better thixotropy and conformability.
3.Good reinforcement effects ,improving adhesives mechanical property ,reducing chemical contractility and coefficient of thermal expansion(CTE) when solidify ,improving thermal conductivity,heat resistance and adhesive force, even hardness ,compression strength and corrosion resistance . good lubrication action, improving processing condition and bonding performances .
4.Small particle size, big specific surface area, good chemical solubility with adhesives after surface treatment. adjusting viscosity and preventing sagging in adhesives. effectively improving soft ,drawing force and irregularity in colloid products .
