Hollow glass sphere can be widely used in outdoor coatings with characteristics of weather ability, sun-proof and heat insulation, automotive coatings, vessel antifouling coatings, anti-corrosion coatings, etc., which play the roles as below.

• Reduce VOC: In the case of high filler amount, the viscosity of coating did not increase greatly, which can reduce the usage amount of each organic component in coating, to reduce the discharge of harmful substances in the process of using coating, effectively reduce VOC index.
• High fluidity: ball structure is like ball bearings, which has lubrication effect in paint, thus reducing the viscosity of paint, increase fluidity.
• Low oxygen/water penetration: Since the size of hollow spheres are widely distributed, it can improve stacking performance, reduce void space, in this way it slows down the penetration rate, block the circuit channels, isolate H2O and Oz to fail to produce electrolytes, which delay rusting attack time and get good stable long-term protection. The particle size of hollow glass sphere is micron sized, which prevent the collapse of the coating after drying and improve the dry film thickness, in this way, it delays the arrival of H2O and Oa to the surface of the steel plate.
• Reduce shrinkage and cracking: spheroid, anisotropic consistency, which reduce the warping and shrinkage of coating film caused by inconsistent stress.
• Barrier effect and inhibition effect: The dispersion and barrier effect of zinc powder can be improved by adding hollow glass sphere inside. Trapping chloride ions, which inhibit and prevent corrosive particles from penetrating down to the surface of the base materials.
