Product Application:
The main application directions of hollow microbeads: aerospace, 5G communication, military Marine, vehicle lightweight, building energy saving, oilfield cementing, rubber elastomer, industrial corrosion prevention, cosmetics, adhesives and other fields.
Application of hollow glass beads in adhesives:
Hollow glass beads are lightweight, hollow, high-strength glass spheres with high strength/density ratio, suitable for silicone, epoxy resin, acrylic acid, polyurethane, synthetic rubber and other adhesives, because of their own characteristics to give adhesives a series of excellent properties:

1. Microsphere effect: the smallest specific surface area, low oil absorption value, reduce the amount of resin, so that the adhesive has a lower viscosity, so that the adhesive has better flow and processing performance; Anisotropic consistency, so that the adhesive will not warp and shrink due to inconsistent stress after processing.
2. Glass material: has high chemical stability, as a filler will not react with the substrate or other substances, suitable for a variety of systems
3. Hollow sphere: low density, reduce adhesive density, reduce volume cost, low thermal conductivity, so that the adhesive has the characteristics of heat insulation and low thermal conductivity,
4. Micron particle size: improve the rheological properties of the adhesive, while improving thixotropy, small microspheres fill the void of large microspheres, thereby increasing its solid content and reducing VOC; Easily dispersed, not reunited;
5. Other characteristics: It can also produce a frosting effect to improve the wear resistance of the resin and improve the dielectric properties of the material
6. Color is white, good color compatibility

Hollow glass beads in anti-corrosion coating application:
Hollow glass beads can be widely used in weatherproof anti-corrosion coatings, automotive coatings, ship anti-fouling coatings, pipeline anti-corrosion coatings and so on. It can play the following roles in the paint:

1. Reduce VOC: In the case of high addition amount, the viscosity of the paint is not greatly increased, which can reduce the amount of organic ingredients in the paint, reduce the emission of harmful substances during the use of the paint, and effectively reduce VOC indicators.
2. High fluidity: The ball structure is similar to ball bearings, which plays a lubricating role in the paint, thereby reducing the viscosity of the paint and increasing the fluidity.
3. Low oxygen/water penetration: hollow glass beads are composed of hollow spheres of different particle sizes, with wide particle size distribution, improving stacking performance, reducing voidage and slowing down penetration, blocking circuit channels, isolating H0 and O, and failing to produce electrolytes. Delay the attack time of corrosion and obtain good and stable long-term protection. The micrometer size of the hollow glass beads prevents the collapse of the coating, improves the dry film thickness of the coating, and delays the arrival of H20 and O: to the surface of the steel plate.
4. Reduce shrinkage and cracking: positive sphere, anisotropic consistency, so that the coating after film formation to reduce due to stress inconsistency caused by warping and shrinkage
5. Barrier effect and inhibition effect: Hollow glass beads improve the dispersion and barrier effect of zinc powder. Trapping chloride ions acts as a restraining effect, preventing corrosive particles from penetrating downward into the substrate surface.

Hollow glass microbeads in building energy saving application:
Hollow glass beads are widely used in reflective heat insulation coatings, giving reflective heat insulation coatings special functions. The reflective heat insulation coating becomes a new kind of cooling coating, which has the function of reflection, radiation and heat insulation. The coating can reflect the sunlight in the range of 400nm-2500nm efficiently, prevent the heat of the sun from accumulating on the surface of the object, and cool down the heat radiation, and radiate the heat on the surface of the object into the air to reduce the temperature of the object. At present, this reflective heat insulation coating is not only used in military and aerospace equipment, but also widely used in pipelines, oil storage tanks, industrial plants, large grain storage warehouses, etc.

Excellent performance of hollow glass beads in reflective heat insulation coating:

1. The reflection ratio of hollow microbeads to near infrared light is much higher than that of common fillers. It can effectively reduce the radiation heat transfer and conduction heat transfer to achieve the purpose of heat insulation.
2. The hollow closed sphere, closely arranged hollow glass microbeads contain thin gas inside, and its excellent thermal conductivity (0.038~0.085W/m.K), so that the coating has a very good thermal insulation effect
3. The ball structure is similar to the ball bearing, which plays a lubricating role in the paint, thereby reducing the viscosity of the paint and increasing the fluidity.
4. It can adsorb nano-sized fillers, help nano-sized fillers disperse, prevent their agglomeration and deposition, and make them more evenly dispersed in the resin emulsion.
