(a)
A security interest may be created in an accession and continues in collateral that becomes an accession.
(b)
If a security interest is perfected when the collateral becomes an accession, the security interest remains perfected in the collateral.
(c)
Except as otherwise provided in subdivision (d), the other provisions of this chapter determine the priority of a security interest in an accession.
(d)
A security interest in an accession is subordinate to a security interest in the whole which is perfected by compliance with the requirements of a certificate of title statute under subdivision (b) of Section 9311.
(e)
After default, subject to Chapter 6 (commencing with subdivision 9601), a secured party may remove an accession from other goods if the security interest in the accession has priority over the claims of every person having an interest in the
whole.
(f)
A secured party that removes an accession from other goods under subdivision (e) shall promptly reimburse any holder of a security interest or other lien on, or owner of, the whole or of the other goods, other than the debtor, for the cost of repair of any physical injury to the whole or the other goods. The secured party need not reimburse the holder or owner for any diminution in value of the whole or the other goods caused by the absence of the accession removed or by any necessity for replacing it. A person entitled to reimbursement may refuse permission to remove until the secured party gives adequate assurance for the performance of the obligation to reimburse.
