ABSTRACT:
A method for measuring binder characteristics in a mat of binder coated mineral fibers, the binder having a first cure indicator constituent, the amount of which changes at a first rate as the binder is cured, and a second cure indicator constituent, the amount of which changes at a second rate, different from the first rate, as the binder is cured, comprising radiating the mat and binder with first, second, third and fourth wavelengths of electromagnetic radiation, the first wavelength being absorbed by the binder including the first cure indicator constituent, the second wavelength being a reference for the first wavelength and being not absorbed by the binder or the cure indicator constituents, the third wavelength being absorbed by the binder including the second cure indicator constituent, and the fourth wavelength being a reference for the third wavelength and being not absorbed by the binder or the cure indicator constituents, and further sensing the amount of energy of the first, second, third and fourth wavelengths transmitted through the mat and the binder, and, finally, determining the degree of cure and/or the amount of binder from the sensed energies.
