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-8690-3(POL, A)	Cream Liquid	1.03~1.13	1000~3000	18 / 220
HD-2042(ISO, B)	Liquid	1.08~1.20	50~110	20 / 235

Processing
,.60-70ºC(6-10,,).,A..
Please preheat materials at 60~70ºCfor 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.
