Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
A mass of intermeshed vitreous fibers bonded to one another at points of contact by a thermoset phenolic resin binder which is the product of heat curing of a composition containing a phenolic resin and a silanolate salt selected from the group consisting of a salt of the formula ##EQU4## and a salt of the formula ##EQU5## where M is a metal having a valence of up to 2, y is equal to 3 divided by the valence of the metal, x is an integer from 3 to 6 and z is an integer from 1 to 3.
Claim 2
Dependent Claim
98 words
A mass of intermeshed vitreous fibers bonded to one another at points of contact by a thermoset phenolic resin binder which is the product of heat curing of a composition containing a phenolic resin and a silanolate salt selected from the group consisting of a salt of the formula ##EQU4## and a salt of the formula ##EQU5## where M is a metal having a valence of up to 2, y is equal to 3 divided by the valence of the metal, x is an integer from 3 to 6 and z is an integer from 1 to 3.
Claim 3
Dependent Claim
13 words
A mass as defined in claim 1 wherein the fibers are glass fibers.
Claim 4
Dependent Claim
17 words
