This article will address how amorphous silica technology is differentiated and engineered to create specially tailored solutions to enhance the performance of coatings and will highlight the latest technical developments in this field.
28 Ιουλ 2023 · Silica sand is a crucial component in the paint industry, serving various purposes in decorative and industrial paints. Its unique properties, including excellent adhesion, reinforcement, and resistance, make it an indispensable ingredient in paint formulations.
19 Οκτ 2000 · WASHINGTON — The final report of a study on health risks posed by exposure to crystalline silica in latex paint concludes that such exposure appears to present “no demonstrable lifetime carcinogenic risk” to do-it-yourself or professional painters engaged in sanding or spray-painting activities.
silica is shown in Figure 1. The most common types of silica used in modern coatings are produced either by a liquid phase process of precipitation or gas phase process of lame hydro-lysis. Precipitated silica is produced by the controlled reaction of sodium silicate (“water glass”) and sulfuric acid similar to the production of silica gels.
OEHHA listed crystalline silica (of airborne particles of respirable size) on the Prop. 65 list on October 1, 1988. The listing includes an exemption (Safe Use Determination) for crystalline silica in interior lat latex paint.
11 Φεβ 2004 · As we understand from this study and your letter, flat latex paints can contain as much as 6 percent crystalline silica in the form of cristobalite, although most formulations contain less than 1 percent crystalline silica.
RCS is commonly used to refer to the tiny particles (at least 100 times smaller than ordinary grains of sand) of crystalline silica that are too small to be seen by the human eye. They can remain in the air for extended periods of time and inhaled deeply into the lungs.
