This Part   deals with security interests in accessions to personal property.

A security interest in goods that become an accession to other goods continues in the accession.

The Part   sets out the priority between an interest (whether or not a security interest) in an accession and the goods to which the accession is affixed.

A security interest arising in an accession before it is affixed to goods has priority over a security interest in the goods as a whole. However, there are exceptions relating to interests in the whole created after the accession is affixed and before the security interest in the accession is perfected.

A security interest arising in an accession after it is affixed will ordinarily be subordinate to an existing interest in the other goods (unless, for example, the holder of the existing interest agrees otherwise) and to a later interest in the other goods that arises before the interest in the accession is perfected.

The Part   also deals with the removal of accessions by a secured party who has an interest in the accession.
