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-1072Q(POL, A)	Cream liquid	1.13~1.18	1800~2400	18 / 220
HD-2040H(ISO, B)	Liquid	1.18~1.20	200~300	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.

HD-1072Q (POL, A)	Hardener/g	water/g	catalyst/g	other
18 kg(one drum)	0	70~80	250	It depends
220 kg (one drum)	0	850~1000	3000	It depends

Reactivity and product performance

Test Items	Reactivity parameters	Test Items	Product performance
Ratio of (A+C) and B material	100/70~72	Moulding density(g/cm^3)	0.40~0.45
Material temperature (^oC)	40~45/38~42	Hardness(23ºC)	47~55C 30~38A
Cream time (s)	4~6	Tensile strength(MPa)	≥3
End of rise time (s)	15~25	Elongation(%)	≥300
Free rise density (g/cm^3)	0.25~0.28	Tear strength(kN/m)	≥13
Metal mold temperature (^oC)	45~55	Flexing resistance(23ºC)	8 80,000 times no crack
Demould time(min)	1.5~2	DIN DIN abrasion resistance(mm3)	≤600

The ratio based on the best value varies with the type and quantity of added paint additives.
