Abstract
Abstract The invention is methods and compositions for removing bonding agents from the hard surfaces of machinery and, in its most preferred mode packaging equipment. The release composition comprises lecithin and a hydrophobic carrier. The method comprises the steps of applying a release composition to the surfaces of the packaging equipment. The packaging equipment is then used. Any bonding agent deposited on the treated areas of the packaging equipment may then be removed. The invention is applicable to any number of package and container manufacture environments including package assembly, package sealing, product sealing, and labeling.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
A method for removing bonding agents from a substrate, said method comprising the steps of: (a) applying a release composition to a substrate to form a barrier layer, said release composition comprising an effective adhesive bond releasing amount of lecithin and an amount of hydrophobic carrier effective to provide a barrier layer when said composition is applied on the intended substrate; (b) contacting the treated substrate with a bonding agent; and (c) removing any bonding agent from the areas of the substrate treated with the release agent, wherein the hydrophobic carrier is selected from the group consisting of an animal-based oil, a vegetable oil, a mineral oil, and mixtures thereof.
Claim 2
Independent Claim
110 words
A method for removing bonding agents from a substrate, said method comprising the steps of: (a) applying a release composition to a substrate to form a barrier layer, said release composition comprising an effective adhesive bond releasing amount of lecithin and an amount of hydrophobic carrier effective to provide a barrier layer when said composition is applied on the intended substrate; (b) contacting the treated substrate with a bonding agent; and (c) removing any bonding agent from the areas of the substrate treated with the release agent, wherein the hydrophobic carrier is selected from the group consisting of an animal-based oil, a vegetable oil, a mineral oil, and mixtures thereof.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein said bonding agent is selected from the group consisting of a thermoplastic adhesive, a thermosetting adhesive and mixtures thereof.
Claim 4
Dependent Claim
26 words
The method claim 1 wherein said bonding agent is selected from the group consisting of a solvent based adhesive, an emulsion based adhesive, and mixtures thereof.
Claim 5
Dependent Claim
20 words
The method of claim 1 wherein said barrier layer has a thickness of form about 1 mil to 20 mils.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein said release composition has a viscosity of from about 5 cps to 1200 cps at 25° C.
Claim 7
Dependent Claim
18 words
The method of claim 1 wherein said barrier layer is applied to said substrate as an aerosol spray.
Claim 8
Dependent Claim
16 words
The method of claim 1 wherein said barrier layer is applied to said substrate by wiping.
Claim 9
Dependent Claim
21 words
The method of claim 1 wherein said barrier layer has a heat stability up to a temperature of about 275° C.
Claim 10
Dependent Claim
10 words
A barrier layer resulting from the method of claim 1.
Claim 11
Dependent Claim
33 words
The method of claim 1 wherein said substrate comprises a material selected from the group consisting of a ceramic material, a metal-alloy material, a synthetic polymeric material, a composite material, and combinations thereof.
Claim 12
Dependent Claim
13 words
The method of claim 1 wherein the mineral oil is mineral seal oil.
