Abstract
Abstract The present invention provides an improved resinous, cross-linkable solid coating composition and a method whereby the same is applied to a substrate in neutral medium by action of heat and pressure. The present invention is characterized by cross-linking of a resinous mixture including plasticizer and vulcanizing agents which saturate the multiple bonds of the substrate or those of its chemical functionalities.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
217 words
An improved method for application of a resinous solid coating composition to substrates, comprising: a. providing a resinous, cross-linkable coating composition in a suitable solvent, characterized by the cross-linking of a resinous mixture including plasticizer and vulcanizing agents, said compositions cross-linking in a neutral medium under suitable conditions of temperature and pressure, said temperature being within the range of about 0° C to 300° C, and said cross-linkable composition capable of retaining fusibility properties for more than one year; b. applying a coating of said composition to a suitable temporary anti-adhesive support means at a temperature below the cross-linking temperature of said composition; c. allowing said coating on said anti-adhesive support means to dry to form a film thereon; d. placing the exposed surface of said film in contact with a substrate to which said coating composition is to be applied; e. subjecting said film in contact with said substrate to sufficient heat and pressure to initiate cross-linking of said composition, whereby said composition cross-links and forms a solid coating composition affixed to said substrate, said solid coating composition becoming infusible and insensitive to solvents, the ingredients of dry cleaning solution, and to washing; and then f. removing said anti-adhesive support means from said solid coating composition, whereby said application of said solid coating composition is completed.
Claim 2
Dependent Claim
217 words
An improved method for application of a resinous solid coating composition to substrates, comprising: a. providing a resinous, cross-linkable coating composition in a suitable solvent, characterized by the cross-linking of a resinous mixture including plasticizer and vulcanizing agents, said compositions cross-linking in a neutral medium under suitable conditions of temperature and pressure, said temperature being within the range of about 0° C to 300° C, and said cross-linkable composition capable of retaining fusibility properties for more than one year; b. applying a coating of said composition to a suitable temporary anti-adhesive support means at a temperature below the cross-linking temperature of said composition; c. allowing said coating on said anti-adhesive support means to dry to form a film thereon; d. placing the exposed surface of said film in contact with a substrate to which said coating composition is to be applied; e. subjecting said film in contact with said substrate to sufficient heat and pressure to initiate cross-linking of said composition, whereby said composition cross-links and forms a solid coating composition affixed to said substrate, said solid coating composition becoming infusible and insensitive to solvents, the ingredients of dry cleaning solution, and to washing; and then f. removing said anti-adhesive support means from said solid coating composition, whereby said application of said solid coating composition is completed.
Claim 3
Dependent Claim
38 words
The improved method of claim 1, wherein said suitable solvent in which said resinous, cross-linkable coating composition is provided is a solvent having a boiling point which is below the cross-linking temperature of said resinous, cross-linkable coating composition.
Claim 4
Dependent Claim
28 words
The improved method of claim 1, wherein said suitable anti-adhesive support means is a support means having a coating selected from the group consisting of silicone and polytetrafluorethylene.
Claim 5
Dependent Claim
13 words
The improved method of claim 1, wherein said film is a continuous film.
Claim 6
Dependent Claim
13 words
The improved method of claim 1, wherein said film is a discontinuous film.
Claim 7
Dependent Claim
17 words
The improved method of claim 1, wherein said solid coating composition is impermeable and resistant to wear.
Claim 8
Dependent Claim
18 words
The improved method of claim 1, wherein the fluidity of said resinous, cross-linkable coating composition may be varied.
