Abstract (en)
[origin: WO2006119982A1] A melamine-formaldehyde resin solution has a formaldehyde/melamine ratio smaller than or equal to 1.5, at which it possesses a water compatibility ranging from 0.15 to 4.0 at 20 °C, and a stability of at least 5 hours at a F/M ratio of 1.0, a stability of at least 6 hours at a F/M ratio of 1.1, a stability of at least 13 hours at a F/M ratio of 1.2, a stability of at least 24 hours at a F/M ratio of 1.3, a stability of at least 50 hours at a F/M ratio of 1.4, and a stability of at least 200 hours at a F/M ratio of 1.5, the stability of the resin solution being linearly dependent, within the range boundaries 1.0<F/M<1.1, 1.1<F/M<1.2, 1.2<F/M<1.3, 1.3<F/M<1.4, 1.4<F/M<1.5, upon the stabilities of the corresponding F/M range boundaries. While having a low formaldehyde content, the melamine-formaldehyde resin solution has adequate storage stability and water compatibility, and can be easily produced without the admixture of modifiers.
