Description of key information

Due to the nature of the product, there is a range of viscosities. Based the national German test guideline DIN 53019 (rotational viscosimeter method), the viscosity range for the substance oligomerisation and alkylation reaction products of 2-phenylpropene and phenol (OAPP) (previous name phenol, methylstyrenated) begins at 100 mPa s and extends to 1200 mPa s at 25°C.

Key value for chemical safety assessment
