Hollow glass microspheres are glass microspheres with low density, light weight and high strength. Due to the hollow characteristics, compared with ordinary glass beads, it has the characteristics of light weight, low density and good thermal insulation performance. The method is directly added to the coating system, so that the coating film formed by the curing of the coating has thermal insulation properties. In addition to its low oil absorption and low density, adding 5% (wt) can increase the finished product by 25% to 35%, thereby not increasing or even reducing the unit volume cost of the coating.
Hollow glass microspheres are closed hollow spheres, which are added into the coating to form many microscopic independent thermal insulation cavities, thereby greatly improving the insulation of the coating film against heat and sound and playing a good role in heat insulation and noise reduction. Make the coating more waterproof, anti-fouling and anti-corrosion properties. The chemically inert surface of the microbeads is resistant to chemical corrosion. When the film is formed, the particles of the glass microbeads are closely arranged to form a low porosity, so that the coating surface forms a protective film that has a blocking effect on moisture and corrosive ions, which plays a good role in protection. effect.

The spherical structure of hollow glass beads makes it have a good dispersion effect on impact force and stress. Adding it to the coating can improve the impact resistance of the coating film and can also reduce the thermal expansion and contraction of the coating. of stress cracking.

Better whitening and shading effect. The white powder has a better whitening effect than ordinary pigments, effectively reducing the amount of other expensive fillers and pigments (compared with titanium dioxide, the volume cost of microbeads is only about 1/5) Effectively enhance the adhesion of the coating focus. The low oil absorption characteristics of glass microbeads allow more resin to participate in the film formation, thereby increasing the adhesion of the coating by 3 to 4 times.

Adding 5% of microbeads can make the coating density from 1.30 to below 1.0, thus greatly reducing the coating weight and avoiding the phenomenon of wall coating peeling off.

Microbeads have a good reflection effect on ultraviolet rays, preventing the coating from yellowing and aging.

The high melting point of the microbeads greatly improves the temperature resistance of the coating and plays a very good role in fire prevention. The spherical particles of the microbeads play the role of bearings, and the friction force is small, which can enhance the flow coating performance of the coating and make the construction more convenient.

Recommendations for use: The general addition amount is 10% of the total weight. The microbeads are surface-treated and have low density, which makes the coating prone to increase in viscosity and float during storage. We recommend increasing the initial viscosity of the coating (by increasing the The added amount of thickener controls the viscosity above 140KU), in this case, the floating phenomenon will not occur because the viscosity is too low, and the particles of each material in the system are reduced in activity due to the high viscosity, which is beneficial to control the viscosity. stability. We strongly recommend the following addition method: because the microbeads have thin particle walls and low shear resistance, in order to fully utilize the hollow characteristics of the microbeads, it is recommended to take the final addition method, that is, put the microbeads at the end of the The addition is dispersed by stirring equipment with low speed and low shear force as much as possible. Because the spherical shape of the microbeads has good fluidity and the friction between them is not large, it is easy to disperse. It can be moistened completely in a short time, just prolong the stirring time to achieve uniform dispersion.

Microbeads are chemically inert and non-toxic. However, due to its extremely light weight, special care is required when adding it. We recommend a step-by-step addition method, that is, the amount of each addition is 1/2 of the remaining microbeads, and gradually added, which can better prevent the microbeads from floating into the air and make the dispersion more complete.Hollow glass microspheres (HGMs) are lightweight, versatile materials that find applications in various industries, including automotive manufacturing. In the context of automotive refreshing, which likely refers to improving the aesthetic and functional aspects of vehicles, HGMs offer several advantages:
Lightweight: HGMs are extremely light, which helps in reducing the overall weight of automotive parts. Lighter vehicles tend to be more fuel-efficient and have lower emissions, contributing to environmental sustainability and cost savings for the owners.

Enhanced Thermal Insulation: Hollow glass microspheres have low thermal conductivity. When used in automotive parts, they can provide thermal insulation, helping to keep the interiors of the vehicle cooler in hot weather and reducing the load on air conditioning systems.

Improved Acoustic Insulation: HGMs can be incorporated into materials to enhance sound insulation. This results in a quieter interior, reducing road noise and providing a more comfortable driving experience.

Dimensional Stability: HGMs can improve the dimensional stability of materials. In the context of automotive parts, this means that components are less likely to warp or change shape under different temperature and humidity conditions, leading to longer-lasting and more durable parts.

Better Surface Finish: When used in paints and coatings, HGMs can contribute to a smoother surface finish. This is particularly important in automotive applications, where the visual appearance of the vehicle is a key factor for customers.

Improved Bonding Strength: HGMs can enhance the bonding strength of adhesives and coatings. In automotive refreshing, this property is valuable for ensuring that newly applied parts or coatings adhere securely to the existing vehicle components, improving overall durability.

Cost-Effectiveness: While the initial cost of incorporating HGMs into materials might be higher, the benefits in terms of reduced material usage, improved fuel efficiency, and longer-lasting components can lead to cost savings in the long run.

Customizability: HGMs can be engineered to have specific properties, such as size, density, and shell thickness. This allows manufacturers to tailor the microspheres according to the requirements of specific automotive applications, ensuring optimal performance.

Environmentally Friendly: Hollow glass microspheres are often made from recycled glass and are environmentally friendly. Using eco-friendly materials aligns with the growing emphasis on sustainability in the automotive industry.

In summary, hollow glass microspheres offer a range of advantages in automotive refreshing, including lightweight construction, improved thermal and acoustic insulation, enhanced surface finish, and cost-effectiveness, making them valuable materials for enhancing both the performance and aesthetics of vehicles.
