摘要

Provided in the present invention is a substantially formaldehyde-free aqueous thermosetting binder resin from urea which can be excluded in the amount of reducing hyderothermal tensile strength in resorcinol and cycloaliphatic dialdehyde glutaraldehyde or a mixture of the same, and a cured binder or included to the amount. the composition provides a binder not containing formaldehyde while having the same performance for the cost with a phenol formaldehyde resin.
