Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 61 words
A non-aqueous coating for glass fibers consisting of an organosilane, an ethylene-ethyl acrylate copolymer, a low molecular weight polyethylene wax, a phenolic-modified terpene resin and an emulsifiable polyolefin, wherein said coating is 100% solids prior to application to surfaces of the glass fibers and wherein the coating is applied to the glass fiber surfaces in the form of a hot melt.
Claim 2
Dependent Claim 61 words
A non-aqueous coating for glass fibers consisting of an organosilane, an ethylene-ethyl acrylate copolymer, a low molecular weight polyethylene wax, a phenolic-modified terpene resin and an emulsifiable polyolefin, wherein said coating is 100% solids prior to application to surfaces of the glass fibers and wherein the coating is applied to the glass fiber surfaces in the form of a hot melt.
Claim 3
Dependent Claim 11 words
The coating of claim 1 in which said silane is gamma-methacryloxysilane.
Claim 4
Dependent Claim 18 words
The coating of claim 1 in which said ethylene-ethyl acrylate copolymer has a melt index of about 20.
Claim 5
Dependent Claim 25 words
The coating of claim 1 in which said low molecular weight polyethylene wax is a microcrystalline wax having a melting point of about 200° F.
