Typical properties of PU resin

Name of products	@40ºC Appearance	Density (g/cm^3 @40^oC)	Viscosity (mPa·s @40 ^oC)	Package Size (kg/drum)
HD-6399-6(POL, A)	Cream liquid	1.13~1.18	1200~1600	18 / 220
HD-2122T(ISO, B)	Liquid	1.18~1.20	150~250	20 / 235

Processing
Please preheat materials at 60~70ºC for 6~10 hours before processing. Then mix fully the whole drum of POL and other additives according to the following table. Finally, respectively transfer POL and ISO to their corresponding tanks.
