Storage at elevated temperatures will lead to an increase in viscosity and a reduction of the NCO content.Storage at low temperature - below 20°C - may lead to turbidity and crystalline separation. By careful heating up to a maximum of 50 °C the product can usually be melted again. Afterwards the product has to be homogenized.
