Recommend Processing Parameters

		Recommended Condition
1. Substrate		ABS, PC, PMMA
2.Pretreatment		MCC recommends wiping the substrate with soft cloth moistened with alcohol and blowing the substrate by anti-static air.
3. Coating material mixture		Under coat: UM-1273U/DIBK(Diisobutyl ketone)/PM(Propylene glycol monomethyl ether)/MIBK(Methyl isobutyl ketone)/Toluene/ MEK(Methyl ethyl ketone)/EA(Ethyl acetate)=100/12/6/3/6/ 6/6 (weight ratio) Top coat: UM-1280T only
4．Coating and Curing	4-1. Coating method	Air spray coating Temp.: 10-30°C, Humidity: below 75%RH
	4-2. Thickness	Under coat: 10–20μm (cured film) Top coat: 10-15μm (cured film)
	4-3. Setting	1-2min. at 50-70°C* (IR lamps) 2-4min. at 50-70°C* (Forced air) *Substrate peak temp.
	4-4. UV Curing	High Pressure Mercury Lamp Dose: 1000-2000mJ/cm²** Peak intensity: 100-200mW/cm²** *Measured by EIT Power Puck II

*Substrate peak temp. **Measured by EIT Power Puck II
