Glass beads have the smallest specific surface area and low oil absorption rate, which can greatly reduce the use of other production components in the coating. The surface of the glass bead vitrified is more resistant to chemical corrosion and has a reflective effect on light. Therefore, the paint coating is anti-fouling, anti-corrosion, anti-UV, anti-yellowing and anti-scratch. The densely arranged hollow glass beads contain dilute gas inside, and their thermal conductivity is low, so the paint coating has a very good thermal insulation effect. Hollow glass microspheres can effectively enhance the flow and leveling properties of the coating. The gas contained in the hollow glass microspheres has good resistance to cold and heat shrinkage, thereby enhancing the elasticity of the coating and greatly reducing the cracking and falling off of the coating caused by thermal expansion and cold contraction. Under the premise of high filling amount, the viscosity of the coating does not increase significantly, so the amount of solvent used can be reduced, which can reduce the emission of toxic gases during the use of the coating and effectively reduce the VOC index.
Recommendations for use: The general addition amount is 10-20% of the total weight. Put the hollow glass microspheres at the end, and use low-speed, low-shear stirring equipment to disperse. Because the microspheres have good spherical fluidity and little friction between them, the dispersion is very easy, and it can be completely moistened in a short time. , slightly prolong the stirring time to achieve uniform dispersion. Hollow glass microspheres are chemically inert and non-toxic, but because they are extremely light, special care is required when adding them. We recommend a step-by-step addition method, that is, adding 1/2 of the remaining microbeads each time, and adding gradually, which can prevent the microbeads from floating into the air and make the dispersion more complete.
