Process for sealing crimps in oil filters

摘要

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 thenc) forming a crimp joint between the two substrates utilizing the respective crimp areas thereof.The process is suitable for forming crimp joints between housing parts of an oil filter.
