The shear strength enhancement due to fumed silica addition is even more striking. Adhesive shear strength typically increases more than a thousand-fold compared to films without particle reinforcement. The chemical bond formation in these adhesive f...…
Significant improvements have been observed in cohesive shear strength and thermo-mechanical properties of waterborne pressure-sensitive adhesives (PSAs) due to the incorporation of highly dispersed fumed silica. Adhesive films with fumed silica cont...…
High-surface-area carbon blacks and fumed silica are more efficient on an equal-weight basis as reinforcing agent than other rheology-control additives. Carbon black is used to build viscosity, provide sag resistance, and increase the cohesive streng...…
Formulators using hydrophilic fumed silicas in moisture curing systems, such as STP or polyurethane, must address premature curing of these systems due to the large water adsorption capacity of hydrophilic silica. Several options are available to sol...…
Formulators use particles to enhance the functionality of existing polymer matrices for adhesive and sealant products. Fumed silica is commonly used as a rheology control additive to provide sag resistance, anti-settling of fillers, and shear-thinnin...…
What is Quartz?Quartz, the most common of all minerals, is composed of silicon dioxide, or silica, SiO2. It is an essential component of igneous and metamorphic rocks. The size varies from specimens weighing a metric ton to minute particles that spar...…
What is Fumed Silica?Since its first production in the early forties of this century, fumed silica has found widespread use in industrial applications. Due to its pyrogenic manufacturing process by combustion of silicon tetrachloride in an oxygen-hyd...…
Saturated Silica Gel can be reactivated by placing it in an oven at 150°C (300°F) for up to 3 ½ hours or until the blue color is restored; note: heating above 162°C (325°F) can damage the gel and render it unable to absorb moisture. Silica Dust will ...…
The product contains silica particles that may be broken down to the respirable size range during shipping, handling, or use and thus may be inhaled. This product contains crystalline silica. Prolonged or repeated inhalation of respirable silica from...…
Silica Gel is a drying and dehumidifying agent that drinks moisture to prevent rust, corrosion, mold, mildew, spoilage, fogging, and condensation. The minimum respiratory protection for a worker who is working with crystalline silica dust, but is not...…
Employers will need to measure the amount of silica workers are exposed to if it is at an action level greater than 25 micrograms per cubic meter of air. Proper protective measures must be taken if silica exposures are above the P.E.L. of 50 microgra...…
The following describes the NIOSH policy for respiratory protection against airborne exposures to crystalline silica. NIOSH recommends using half-facepiece particulate respirators with N95 or better filters for airborne exposure to crystalline silica...…
High energy costs are forcing factories across Europe to shut down. July saw the biggest drop in industrial production in Europe in two years, and the situation is now in crisis mode.…
NUS researchers have developed wireless, ultra-thin and battery-free strain sensors that are 10 times more sensitive than conventional technologies. These light-weight strain sensors can be incorporated into rehabilitation gloves to improve…
The Huawei Mate 20 Lite Blue is a great phone that comes in a blue color. This smartphone runs on Google's Android 8.1 Operating System and offers great browsing. The phone's thin design makes it ideal for people who prefer to use one hand to hold it…
