features of kuraray polyol

low viscosity
<Kuraray polyol> contribute to operating efficiency.
solvent compatibility
<Kuraray polyol> enable lots of formulation possibilities.
polyol compatibility
<Kuraray polyol> are soluble in polyether polyols as well as conventional polyols.

low viscosity

Pre-polymer based on <Kuraray polyol> can be high solid because <Kuraray polyol> enable to reduce pre-polymer viscosity.
This allows <Kuraray polyol> to increase operating efficiency.

polyol compatibility

<Kuraray polyol> P-1010 is compatible with polyether polyol.
Properties of polyurethanes based on polyether polyols are improved by using blended polyol (polyether polyol with <Kuraray polyol>).
