Beschreibung
Zusammenfassung:	Curable urea formaldehyde binder compositions are provided which are useful in coated abrasive and wood engineering applications, in a time released fashion. The time released curable binder compositions include a urea formaldehyde resin and an aryl phosphite in varying concentrations. The curable binder compositions of the present invention provide desirable working times and faster curing times under ambient or near ambient conditions. L'invention concerne des compositions de liant formaldéhyde d'urée durcissables, utiles dans des applications de technologies du bois et de technologies d'abrasif enrobé, de manière temporisée. Ces compositions de liant durcissables de manière temporisée comprennent une résine formaldéhyde d'urée et un aryle phosphite, dans des concentrations variables. Ces compositions de liant durcissables permettent d'obtenir des temps de travail voulus et des temps de durcissement raccourcis dans des conditions ambiantes ou proches de conditions ambiantes.
