Hollow glass microspheres have a series of advantages such as lightweight, high-strength, thermal insulation, sound insulation, flame retardancy, insulation, and stable physical and chemical properties, making them an excellent filler for thermal insulation coatings. The use of hollow glass microspheres as thermal insulation coatings has become increasingly widely used in fields such as good workability and excellent thermal insulation properties.
Advantages of hollow glass microspheres:
1. Excellent insulation and noise reduction performance. Hollow glass microspheres can form dense, uniform, and mutually independent cavities in the coating, providing good insulation and noise reduction effects.
2. Efficient filling performance. Hollow glass microspheres can effectively increase the volume concentration of pigments and fillers, and add 5wt.% Hollow glass microspheres can increase the volume of the finished product by 25% to 35%, thereby not increasing or even reducing the unit volume cost of the coating.
3. Significant weight reduction performance. The true density of hollow glass microspheres is nearly one tenth of that of ordinary paint fillers, so adding a small amount of hollow glass microspheres can significantly reduce the weight of the dry coating.
4. Excellent temperature resistance. Hollow glass microspheres themselves are non combustible and do not support combustion, and their melting point is above 600 ℃, which can greatly improve the temperature resistance of the coating and make it have a good fireproof effect.
5. Excellent construction performance. The regular spherical structure of hollow glass microspheres can pray for the effect of ball bearings during coating construction, increase the flow and application performance of the coating, and effectively improve the coating’s construction performance.
6. Green and environmentally friendly. Hollow glass microspheres can be used in all water-based resin systems and significantly reduce the amount of various coating additives, effectively reducing the VOC content of coatings.
