** NBAC = 100 for reference (NBAC = n Butyl Acetate)
* Solubility Test
Paint : Solvent (Sample + Toluene 9) = 2 : 1 which is titrated by n-Hexane
* Detergency Test
Test Procedure is as follows
Plate is dipped in paint of polyurethane resin.
Take out plate to dry for 1 min. in air.
Dip the plate in solvent for 30 seconds.
Take out plate and dry for 30 seconds in air.
One cycle from procedure 2 to 4.
Repeat procedure 2 to 4 until paint is peeled off.
* Drying Test
Paint (polyurethane) : Solvent 2 : 1 which is coated on the plate. The drying
time is measured by finger contact.
