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.
Hollow glass beads is a small density, glass microspheres lightweight, high strength. The main ingredient is Sio2 and Al2o3, because of its unique chemical properties, physical properties, and hollow spherical, compared with ordinary glass beads, light weight, low density, good heat insulation performance characteristics, is thermal insulation coatings the main raw material. Because of its smaller particle size, equal to or greater than the ordinary paint fineness of the filler, which can be added directly to the filler coating systems, the coating having a cured coating film formed by thermal insulation properties.
Hollow glass microspheres Application Features:
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.
