Application


Fumed silica is the material of choice for adhesive and sealant modification. The addition of fumed silica to silicone sealants and adhesives significantly increases bond strength and ensures free flow, prevents caking and sags during cure, slumps, sags, maintains clarity, reinforcement, shear resistance Cut etc. Its mechanism of action is that when it is dispersed in sealants and adhesives, hydrogen bonds are formed between different particles through the silanol groups on their surfaces to form a silica aggregate network, which limits the fluidity of the system and increases the viscosity. To thickening effect; under the action of shear force, the silica network is destroyed, resulting in a decrease in the viscosity of the system and a thixotropic effect, which is convenient for construction. Once the shear force is removed, this network structure can be re-formed, effectively preventing the compound from sagging during curing.

Adding a small amount of fumed silica to the unsaturated resin can give the resin excellent transparency and excellent physical properties, and improve the quality of downstream products.In the gel coat resin, the addition of fumed silica can improve its thixotropy, so that the resin has good tensile strength, bending resistance, water resistance, heat resistance and other properties, thereby prolonging the service life; in thixotropic resin, gas phase The addition of silica can give it excellent thixotropic properties and reduce the flow and dripping during use; in the putty, fumed silica can be used as an anti-settling agent, with excellent anti-settling effect and excellent performance.

In heat-set offset printing inks, the use of hydrophilic fumed silica can speed up the drying speed of the ink and reduce the phenomenon of smudging and blurring of the ink; in offset printing inks, the use of hydrophobic fumed silica , can reduce the water absorption of the ink, eliminate foam, improve the depth of the ink without affecting its surface gloss; in gravure printing, flexographic printing and silk printing, the use of fumed silica can adjust the viscosity and prevent pigment sedimentation; fumed dioxide Silicon can also be used to control the flow of printer ink, control the fluidity of ink to obtain clear printing; it can be used as a dispersant and flow control agent in the toning of ink cartridges in copiers and laser printers.
