Free abrasive of processor could be good surface roughness and not more created qualitative change，Both Lapping and Polishing processor could thinned、finished surface。

UTSD-SP01suspension lapping vehicle be formulated to free abrasive slurry that apply to processor of sapphires substrate and LED chip backside be thinned。First UTSD-SP-01 be dissolved in water then abrasive such as SiC、B4C、CBN、Diamond micro-powder、Al2O3、Silica、FO and so on，slowly placed upside down and to agitate so that will be on line device to work。

The other applications of free abrasive what do include silicon wafer、optical glass、quartz transistor、ceramics or metals substrate industries。

UTSD-SP01Suspention Lapping Vehicle property：

1. appearance：light amber color
2. stability：stable color
3. pH(@1% in water)：7.0 ~ 7.5
4. specific gravity：1.00±0.02
5. flash point：＞100℃
6. water base：easily dissolved in water
7. lower dynamic viscosity：slurries are stable suspension/dispersion to be good resistant shear
8. good suspension：abrasive not be aggregated again，improved TTV and Ra value
9. competed under equal conditions：reduced to use dosage
10. formula：rinsed easily；will not leave films or residues；biodegradable materials；inhibited plate corrosion
