There filling performance energy efficient, low low oil, density, added 5% (wt) will be able to make the finished product increased by 25% to 35%, so as not to increase or even reduce the cost per unit volume of the coating. Hollow glass beads particles confined hollow spheres added to the coating formation of many independent microscopic cavity insulation, thus greatly improving the coating on the thermal and sound insulation, play a very good thermal insulation and noise reduction effect. The coating has a more waterproof, anti-fouling, corrosion resistance. When the surface of the hollow glass microspheres are chemically inert chemical resistance, as the film tightly packed particles of glass beads, the formation of low porosity, the coating formed on the surface of the moisture and corrosion caused by the blocking effect of ions protective film, played well protective effect.

Hollow glass beads spherical structure makes the impact force and stress have a good dispersion, added to the paint can well improve the resistance to external impact properties of the film, and the coating can be reduced due to thermal expansion and contraction the stress cracking.

Filling the hollow glass microspheres can effectively reduce other expensive fillers and pigments dosage (compare with titanium dioxide, but its volume costs beads 1/5) effectively enhance the adhesion of the coating. Low oil absorption properties of glass beads so that more resin can participate in film formation, so that the adhesion of the coating increased 3 to 4 times.
