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-6670(POL, A,)	Liquid	1.13~1.18	1000~1500	18 / 220
HD-1919(ISO, B)	Liquid Líquido	1.18~1.20	350~450	20 / 235

Processing
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.
