Application of Hollow Glass Beads in Thermal

  • Insulation Coatings Industry Glass beads have the smallest specific surface area and low oil absorption, which can greatly reduce the use of other ingredients in the coating. Glass beads are more resistant to chemical corrosion and have a reflective effect on light. Therefore, the coating coating with anti-fouling, anti-corrosion, anti-UV, anti-yellowing and anti-scratch effect. The tightly arranged hollow glass beads contain a thin gas inside, and the thermal conductivity is low, so the coating has a very good thermal insulation effect.

    Hollow glass beads can effectively enhance the flow of the coating, leveling. Hollow glass beads containing gas has good resistance to hot and cold shrinkage, thereby enhancing the flexibility of the coating, greatly reducing the coating due to thermal expansion and contraction caused by cracking and shedding.

    In the case of high filling capacity, the viscosity of the coating is not obvious, so the amount of solvent can be reduced, can reduce the use of toxic gases in the process of emissions, effectively reduce the VOC index. Suggested use: the general amount of added for the whole weight of 8-20% Suggest the following method: Finally add. The hollow glass beads into the last to add, the use of low-speed, low shear mixing equipment dispersion, because the micro-ball spherical flow is good, between the friction is not large, so easy dispersion, a short period of time can be completely wet , Slightly extended mixing time to achieve uniform dispersion can be. Hollow glass beads are chemically inert, non-toxic, but because of their very light, so add Outdoor Waterproof Floor - Shanghai Seven Trust special attention. We recommend a stepwise addition method, that is, each time the amount of the remaining beads into the 1/2, and gradually added, so that it can be very good to avoid the beads floating into the air and make the dispersion more complete.
