A process for producing a sealed crimp joint between two substrates, each substrate having a predefined crimp area utilized to form the crimp joint. The process includes the steps of: a) applying a photocurable sealant composition to a portion of the crimp area of at least one of the substrates, b) irradiating the photocurable sealant in place on the substrate to fully cure the sealant, and then c) forming a crimp joint between the two substrates utilizing the respective crimp areas thereof.

1. A process for producing a sealed crimp joint between two substrates, each substrate having a predefined crimp area utilized to form the crimp joint, the process comprisinga) applying a photocurable sealant composition to a portion of the crimp area of at least one of the substrates,b) irradiating the photocurable curable sealant in place on the substrate with energy effective to cure the sealant to an immobile state, and thenc) forming a crimp joint between the two substrates utilizing the respective crimp areas thereof. 2. A process as in claim 1 wherein the photocurable sealant is applied with a sprayer, extruder, liquid film dispensing valve or screen printing. 3. A process as in claim 2 wherein the photocurable sealant has a viscosity in the range of 10 to 100,000 mPa.s. 4. A process as in claim 3 wherein said viscosity is in the range of 100 to 100,000 mPa.s. 5. A process as in claim 1 wherein the photocurable sealant is a (meth)acrylate based sealant. 6. A process as in claim 1 wherein the sealant is applied at a thickness of 0.001 inches to 0.020 inches (0.025 mm to 0.51 mm). 7. A process as in claim 6 wherein said thickness is from about 0.005 inches to about 0.006 inches (0.13 mm to 0.15 mm). 8. A process as in claim 1 wherein the two substrates, when joined, form a housing for an automotive fluid filter. 9. A process as in claim 1 wherein the two substrates when joined, form a housing for an oil filter. 10. A process as in claim 9 wherein one of the substrates is a housing shell and the other is a circular nutplate, and the sealant is applied to the crimp area of the nutplate as an annular ring. 11. A process as in claim 1 wherein after the sealant is applied and cured, but before the crimp joint is formed, the substrate having the cured sealant thereon is inspected to determine at least one of the presence, location, thickness or cure depth of the cured sealant. 12. A process as in claim 1 wherein the sealant, when cured, has a flexural modulus of about 120,000 psi or less. 13. A process as in claim 12 wherein said flexural modulus is in the range of from about 50 to about 90,000 psi. 14. A process as in claim 13 wherein said flexural modulus is in the range of from about 500 to about 60,000 psi. 15. A process as in claim 1 wherein the photocurable sealant is a photocurable (meth)acrylate, epoxy, vinyl ether, styryloxy, or thiol-ene based sealant. 16. A process as in claim 1 wherein the photocurable sealant comprises a compound providing an organic polymer backbone, a silicone polymer backbone or a mixture of any two or more thereof. 17. A process as in claim 1 wherein the photocurable sealant further comprises a colorant, fluorescent agent, phosphorescent agent or mixture of any two or more thereof. 18. A process as in claim 1 wherein, in the irradiation step b), the photocurable sealant is cured to the solid state through the depth thereof. 19. A process as in claim 1 wherein the sealant has a secondary cure mechanism effective to continue curing the sealant after the irradiation step b). 20. A crimp joined product produced by the process of claim 1. 21. An oil filter comprising a housing produced by the process of claim 9.
