The reflective properties of micro glass spheres (MGS) such as Solid Micro Glass Spheres (SMGS, “glass beads”) and Micro Hollow Glass Spheres (MHGS, “glass bubbles”) are utilized in various applications, for example, as retro-reflector for traffic road stripe paints or facade paints. The reflection behavior of the spheres can be further adapted by coating the surfaces of the spheres, e.g., by titanium dioxide or a metallic coating. Such coated spheres can be employed as, e.g., mid infrared (MIR)-reflective additives in wall paints to increase the thermal comfort in rooms. As a result, the demand of heating energy can be reduced. In this paper, the increase of the MIR-reflectance by applying an aluminum coating on MGS is discussed.

Introduction

Micro glass spheres (MGS), such as micro solid glass spheres and micro hollow glass spheres, are utilized in various technical fields due to their excellent physical and chemical properties. Solid Micro Glass Spheres (SMGS) exhibit high strength, as well as smooth surfaces, and are excellently suited as grinding and dispersing balls. They are also utilized as fillers in thermoplastics and thermosets to enhance the physical properties of the matrix, like increasing the Young Modulus and hardness. Micro Hollow Glass Spheres (MHGS) are characterized by a low density, as well as by low thermal conductivity. Applied as fillers, e.g., in polymers or building materials, a decrease in weight and minimization of thermal conductivity is possible and could lead to energy savings, especially in the automotive and building industry.
