A security interest in goods that attaches after the goods become an accession is subordinate to the interest of:
(a) a person who has an interest in the other goods at the time when the goods become an accession and who:
(i) has not consented to the security interest in the accession; and
(ii) has not disclaimed an interest in the accession; and
(iii) has not entered into an agreement under which another person is entitled to remove the accession; and
(iv) is otherwise entitled to prevent the grantor from removing the accession; or
(b) a person who acquires an interest in the whole after the goods become an accession, but before the security interest in the accession is perfected.
