Section 9--335. Accessions

(a) Creation  of  security  interest in accession. A security interest
  may be created in an accession and continues in collateral that  becomes
  an accession.
    (b) Perfection  of  security  interest.  If  a  security  interest  is
  perfected  when  the  collateral  becomes  an  accession,  the  security
  interest remains perfected in the collateral.
    (c) Priority  of  security  interest.  Except as otherwise provided in
  subsection (d), the other provisions of this part determine the priority
  of a security interest in an accession.
    (d) Compliance with certificate-of-title statute. 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 Section 9--311 (b).
    (e) Removal of accession after default. After default, subject to Part
  6, 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) Reimbursement  following  removal. A secured party that removes an
  accession from other goods under subsection (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.
