Verre creuxIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The SMC process permits production of moderate to large quantities of dimensionally accurate parts with a high-gloss surface and has significant potential for manufacturing lightweight parts. With proper selection of SMC fillers, the weight of these parts can be reduced even further, because of the high volume taken up by the fillers. Expanded perlite can offer an economical alternative to established lightweight fillers such as hollow glass microspheres. Note de contenu : - Hollow particles through expansion

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : The author discusses the benefits of using perlite in wood clear coats.
Matting in wood clear coats is generally achieved with aggregated synthetic silica. Due to highly porous cluster of particles of synthetic silica, in which the cluster diameter is typically 5-10µm, these materials provide matting at very low dosage. Matting efficiency of silica mainly depends on the particle volume concentration. A higher concentration increases the micro-roughness of the surface, leading to greater matting.
Perlite is an amorphous volcanic rock, which is formed by the rapid cooling of siliceous magma or lava. Perlite ore is a hydrated natural glass, containing typically about 72-75% of SiO2. The hydration occurs from absorption of near-surface water into the glass, resulting in 2-5% of bonded water within its structure. When heated rapidly to its softening temperature (approximately 900°C) the water molecules trapped in the rock evaporate and expand the particles from five to 30 times to their original volume. These expanded particles are actually groups of small rounded, light and insulating glass particles. Ground and milled perlite particels offer several different properties in paint and coatings, most notably : inertness ; hardness and matting.Note de contenu : - Formulations
