MIN-U-SIL Micro Silica


MIN-U-SIL fine ground silica


OriginU.S.A


Specification22.68KG50 pound


MIN-U-SIL fine ground silica is a natural crystal quartz product which exploited by U.S.SILICA. It has high puritythe content of SIO2 more than 99.5% ),even particle size distributionhigh whiteness and brightnesslow moisture content good characteristics. It is especially suitable for applications which require improving the hardness of paint films and reinforce. It can be instead of the import titanium powder to reduce the cost.


According to the particle sizes it has 5 types5 u10 u15 u30 u 40 u

Advantages


1、 Excellent particle separation, the use of statistical procedure to control the production process to insure the high quality and stability.

2、 High purity, it has neutral and chemical inertness properties which is easy for formulation.

3、 Nature crystal particle has excellent abrasive resistance and rigidity

4、 Lower specific surface area to reduce the resin to have high additives and low viscosity

5、 Good processabilitysmall shrinkagesmalll thermal expansionacid alkaline resistancesolvent insulation and mechanical properties.




Applications


Construction coatingroad sign coatingmix with TiO2 to increase coating abrasive resistance and control the gloss by defoaming.


Industrial anti-rust protection coatingMIN-U-SIL has good chemical securityacid resistanceheat resistance and anti-rust resistance properties.


Silicone rubber: MIN-U-SIL can mix with various kinds of titanium powder fillers without any vulcanization effect, it is a good semi-reinforcing additives


Wire and cablesheat resistance, one of the important factors is chemical inert and cost efficiency


Fillerit is used in the polyester、epoxyurethanes materials or mix with phenolic resin.


Plasticused in thermoplastic plastic to improve heat resistance and stability and lower the cost.If used in thermosetting plasticit has good stability and low expansion rate. Furthermore it can mix with resins polyesterepoxyor high temperature insulation material.


Epoxy resin injection moldingMIN-U-SIL has durability without any chemical changes, to improve physical strength in electronic industry. It has high loading capacity to cast the IC board and ignition coil.
