Abstract
A novel composite comprises a substrate having a coating matrix including an initial layer of a perfluoropolymer and an overcoat comprising a fluoroelastomer, a fluoroplastic, a fluoroelastomer/fluoroplastic blend, or a combination thereof. The perfluoropolymer in the initial layer may be a perfluoroplastic, a perfluoroelastomer, or blends thereof. In a separate embodiment, the novel composite includes a substrate coated solely with one or more layers of perfluoroelastomer alone or as a blend with a perfluoroplastic. Where the substrate is not susceptible to hydrogen fluoride corrosion, the composite may include solely one or more layers of a blend of a fluoroelastomer and a hydrogen-containing perfluoroplastic. Cross-linking accelerators may be used to cross-link one or more of the resins contained in the coating layers. Each composite may be topcoated with the layer or layers of a fluoroplastic, fluoroelastomer, and/or a blend thereof. The composite is flexible, exhibits good matrix cohesion and possesses substantial adhesion of the matrix to the material acting as the reinforcement or substrate. A method for making such a composite comprises the unique deployment of a perfluoropolymer directly onto the substrate in a relatively small amount sufficient to protect the substrate from chemical corrosion without impairing flexibility, followed by the application of the overcoat layer.
Description
This invention relates to new and useful fluoro-
Claims (23)
1. A composite having a low modulus of stiffness and good chemical resistance which comprises a substrate coated with a matrix comprising: 5 a) fin initial layer of a perfluoropolymer selected from a perfluoroplastic, a perfluoroelastomer, a blend of perfluoroplastic and perfluoroelastomer, said initial layer being applied as a relatively light coating to maintain a low stiffness modulus for the composite and 10 to provide the substrate with chemical resistance; and b) an overcoat layer of a fluoroelastomer, a fluoroelastomer/fluoroplastic blend, said fluoroelastomer comprising from 10% to 90% by weight of the blend, or a combination thereof. 15
2. A composite according to claim 1 wherein said initial layer is applied to the substrate in an amount sufficient to provide chemical resistance while at the same time leaving any openings in the substrate substantially open so as to maintain flexibility. 20
3. A composite according to claim 1 wherein the initial layer comprises a perfluoropolymer and a lubricating agent.
4. A composite according to claim 1 wherein the substrate is treated with a coupling agent to promote 25 bonding.

18. A method for the manufacture of a composite including a substrate coated with a matrix, wherein the said matrix is formed by a gradation of fluoropolymer layers, which comprises the steps of: 10 i) first applying an initial layer comprising a perfluoropolymer in an amount sufficient to substantially shield the substrate from chemical corrosion without impairing flexibilty; ii) thereafter applying to said initial layer an 15 overcoat layer comprising a fluoroelastomer, a fluoroelastomer/fluoroplastic blend comprising 10-90% by weight of the fluoroelastomer, or a combination thereof.
