(Automobile, Composite FRP Products, Putty Repair)
Appearance: White Fine Powder
Particle morphology: rigid hollow sphere

Average particle size: about 50 mu
Compressive strength: about 5 Mpa
Thermal conductivity: lambda = 0.043W/m.K
Melting point: above 600 C
The role embodied in atomic ash:
1. High filling efficiency, low oil absorption, low density, adding 4-15% (wt) can increase the product volume by 30-40%.
Thus, the unit volume cost of coatings is not increased or even reduced.
2. Hollow glass microspheres are sealed hollow spheres. Many micro-grooves are formed when they are added to the surface of atomic ash coating.
High surface roughness is beneficial to sandpaper grinding.
3. Make the coating have better waterproof, anti-fouling and anti-corrosion performance. The chemical inert surface of hollow glass beads resists chemical corrosion. When it is used as film, the micro-beads are arranged tightly and form a low porosity, which makes the surface of the coating form a protective film which can block moisture and corrosive ions, thus playing a very good protective role.
4. The spherical structure of hollow glass microspheres has a good dispersing effect on impact force and stress, which is added to atomic ash.
It can improve the impact resistance of the coating and reduce the stress cracking caused by thermal expansion and contraction.
5. Better whitening effect. White powder has better whitening effect than ordinary pigments and can effectively reduce its whitening effect.
The volume cost of hollow glass beads is only about 1/4 of that of titanium dioxide.
6. Effectively enhance the adhesion of the coating. The low oil absorption property of hollow glass microspheres enables more resins to participate in film formation, thereby
Enhance the adhesion of the coating.
7. By adding 4%-10% hollow glass beads, the coating density can be reduced from 1.3 to below 0.8, thus greatly reducing the weight of the coating and avoiding the appearance of coating peeling off.
8. Hollow glass microspheres have good reflective effect on ultraviolet radiation and prevent yellowing and aging of coatings.
9. Hollow glass beads have high melting point, which greatly improves the temperature resistance of the coating and plays a very good role in fire prevention.
10. The spherical particles of hollow glass beads act as bearings and have little friction, which can enhance the flowing and smearing properties of atomic ash.
Make the construction more convenient and easy.
