a couple of recent repair project remind popmech's home blogger of the utility of thickening epoxy. diy tip: thicken your epoxy for even more versatility of west systems colloidal silica
fumed silica has a very strong thickening effect. primary particle size is 5 50 nm. the particles are non-porous and have a surface area of 50 600 m 2 /g. the density is 160 190 kg/m 3. production. fumed silica is made from flame pyrolysis of silicon tetrachloride or from quartz sand vaporized in a 3000 c electric arc.
its applications are many, including thickening, epoxy, polyester, and urethane. it is a versatile thickening agent that has even been used to 'thicken' fresh water and sea water. epoxy thickening agent product 71 is an extremely fine particle size silica silicon-dioxide / sio 2 . it is pure white and free-flowing.
silica used in the food and beverage industry is safe to take orally. however, that doesn't mean that silica is always safe for humans. silica actually comes in many forms some safe, some not. crystalline silica, a form that includes quartz, can be toxic if inhaled. crystalline silica is found in rock, brick, and concrete.
an alternative to the every popular fumed silica, ez thick is a cellulose based powder that quickly and easily blends into the epoxy unlike fumed silica . a 1 gallon unit will thicken about 3 quarts of our no blush epoxy into something approaching mashed potatoes in texture and color .
cab-o-sil m-5 by cabot is medium surface fumed silica. it is widely used to provide thickening, thixotrophic shear thinning , and anti-settling behavior in liquid systems. it is most efficient in non-polar to medium polarity systems. offers an excellent balance of thickening efficiency and dispersibility.

silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. it mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe.
a dilatant /daletnt/ also termed shear thickening material is one in which viscosity increases with the rate of shear strain.such a shear thickening fluid, also known by the initialism stf, is an example of a non-newtonian fluid.this behaviour is usually not observed in pure materials, but can occur in suspensions.
dispersions of hydrophilic fumed silica are investigated in a range of polar organic media. the silica forms stable, low-viscosity sols exhibiting shear thickening behavior in a host of liquids, including ethylene glycol and its oligomers and short-chain alcohols, such as n-propanol. in contrast, the silica flocculates into colloidal gels in other liquids, such as glycols with methyl end-caps
