1. CaCO Advantages in Paint and Surface Coatings:
It solidifies
It controls the viscosity
It lowers the cost by reducing the consumption of titanium dioxide
It enhances opacity due to its high whiteness property
It strengthens
It increases the impact resistance of the paint film
It gives brightness to the paint
It prevents the paint films to peel off
It provides a smooth film surface
It has an ultra-hiding power
It has a high dispersion feature
2. CaCO Advantages in Plastic Sector:
Some advantages of the calcite over the plastics are as follows:
Depending on different chemical surface coating, it provides dop oil saving.
It provides pigment saving due to its high
whiteness.
It has a flame retardant property due to its chemical structure.
It increases the writability of the packing materials.
It has a positive effect on notched impact strength.
It has a regulatory impact on the viscosity in polymer.
The micronized calcite used as a filling material in plastic sector:
Must control the rheological properties of PVC plastisols,
Must not include heavy metals causing polymers to age,
Must have high chemical purity,
Must have high whiteness for saving expensive white pigments,
Ground particles must not gather together and agglomerate again,
Must not intake high amount of oil,
Must not absorb the flux oil or the chemical substances used in the formulation,
Must not cause machines to be worn,
Must have homogeneity,
Must have a high rate of whiteness for saving expensive white pigments and
dyeability at high filling levels,
Must disperse easily,
Must enhance hardening, the structural properties of the final product, impact
resistance, stability and resistance against ageing,
Must protect against heating up due to its solidifying effect,
Must prevent blocking on broken film surfaces,
Must be scentless, tasteless and non-toxic.
