摘要:
The invention relates to an isothiazolone-containing preservative which comprises the condensation product of a mixture comprising glycol, urea and formaldehyde. The invention further relates to the use of the preservative in technical products, to the technical product and to the use of the condensation product for stabilizing isothiazolones. The inventive preservative is free from 5-chloro-2-methylisothiazolone and 2-mercaptopyridine N-oxide and derivatives thereof and also has good storage stability in the form of the concentrate, even at elevated temperature.
