Hollow Glass Microspheres

Hollow Glass Microspheres are micron - sized hollow closed spheres filled with rarefied gas. Their thermal conductivity (0.038 - 0.060 W/m·K) gives coatings great insulation. The spherical shape easily forms a high - strength reflective layer. Coatings with them can block over 85% of solar heat, for efficient heat reflection.
Added to zinc - rich primers, they prevent steel structure paint from cracking due to thermal expansion/contraction. They stop crack spread at the start, improving anti - corrosion.
As alkaline - weak and stable inorganic oxides, they can be added to mud systems without reactions, ensuring drilling fluid stability. With low density and high strength, they're good for making low - density drilling fluids for deep wells. Their spherical shape offers good fluidity and lubrication, cutting friction, lengthening equipment life and boosting drilling speed. They fit existing equipment, can be recycled to cut costs.
In adhesives, they cut density, control layer thickness, reduce shrinkage and cracking, and add insulation features. They're suitable for silicone, epoxy, acrylic and polyurethane adhesives. Shengleite offers specially - treated microspheres for different needs.
