Always wear protective gloves and a dust mask when handling this product in its raw state. Amorphous Participated Silica Powder is a synthetic powder that improves the anti-caking and free-flow properties of powders, making them easier to. Respirable silica dust particles are those that are small enough to breathe in and penetrate deep into the lungs causing permanent damage that can lead to. Please note the addition of Fumed Silica will reduce the clarity of clear resin systems meaning it is not ideal for turning clear laminating resin into a clear gelcoat.įumed Silica particles are incredibly small and light and will become airborne as soon as the material is scooped, moved or mixed. Percentages up to 3%+ can be used to make a filler paste (additional filler powders may be required). Copper Slag / Iron Silicate is ideal when a quick and efficient paint stripping process is required. Crystalline silica is present in certain construction materials such as concrete, masonry, and brick and also in commercial products such as some cleansers, cosmetics, pet litter, talcum powder, caulk, and paint.

For maximum effect, allow the Fumed Silica to soak in the resin for as much as a day before thorough mixing.įumed Silica added to resin at a ratio of 0.7% - 1% (by weight) will produce a thixotropic resin. Learn about crystalline silica (quartz dust), which can raise your risk of lung cancer.

Use of a mechanical stirrer will make the process quicker and easier but manual mixing is perfectly possible. Please contact us if you would like to discuss larger quantities.įumed Silica requires significant agitation (stirring) to become fully mixed into a resin. Please choose the pack size you require from the drop-down menu at the top of the page. Our Fumed Silica Thixotropic Powder is sold by volume and is available in 1litre (45g), 5litre (225g) and 10litre (550g) pack sizes. Most semiconductor devices are now packaged in an epoxy polymer composite, which includes silica powder filler for reducing the thermal expansion coefficient. Our Fumed Silica Thixotropic Powder is compatible with all popular resin systems, including polyurethane, epoxy and polyester. Adding a small amount of fumed silica to epoxy resin will significantly increase the thixotropic properties of the resin, effectively turning it into a gelcoat and allowing it to cling to sides of steep moulds without running.

Aerosil® 200 Fumed Silica is an ultra-fine powder used to increase the viscosity (thickness) of resin systems.
