Typical properties of PU resin

Name of products	Appearance	Density (g/cm^3@40^oC)	Viscosity (mPa·s @40^oC)	Package Size (kg/drum)
HD-4060(POL, A)	Liquid	1.13~1.18	900~1200	18 / 220
HD-1900(ISO, B)	Liquid	1.18~1.20	350~450	20 / 235
C008	Liquid	1.18~1.20	350~450	5
C005	Liquid	1.18~1.20	350~450	5
H	Liquid	1.18~1.20	350~450	10

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.

HD-4060 (POL, A)	HD-H/g	water/g	COO8/g	C005
18 kg(one drum)	0	50~55	260	It depends
220 kg(one drum)	0	600~670	3200	It depends
