Low-Formaldehyde binders

A low-formaldehyde binder consists essentially of (A) from 5 to 80% by weight of a water-soluble condensation product of carbonyl number 0-200 which has been prepared by alkaline condensation from 0.1 to 0.4 mole of an aliphatic or cycloaliphatic condensable ketone and 1 mole of formaldehyde, and (B...

Zusammenfassung:	A low-formaldehyde binder consists essentially of (A) from 5 to 80% by weight of a water-soluble condensation product of carbonyl number 0-200 which has been prepared by alkaline condensation from 0.1 to 0.4 mole of an aliphatic or cycloaliphatic condensable ketone and 1 mole of formaldehyde, and (B) from 20 to 95% by weight of 4,5-dihydroxyimidazolidin-2-one and/or an unetherified, partially etherified or completely etherified condensation product thereof with an aliphatic monoaldehyde or dialdehyde.
