§12A-9-315.
   
   (1) If a security interest in goods was perfected and subsequently the
   goods or a part thereof have become part of a product or mass, the
   security interest continues in the product or mass if
   
   (a) the goods are so manufactured, processed, assembled or commingled
   that their identity is lost in the product or mass; or
   
   (b) a financing statement covering the original goods also covers the
   product into which the goods have been manufactured, processed or
   assembled.
   
   In a case to which paragraph (b) applies, no separate security
   interest in that part of the original goods which has been
   manufactured, processed or assembled into the product may be claimed
   under Section 9-314.
   
   (2) When under subsection (1) more than one security interest attaches
   to the product or mass, they rank equally according to the ratio that
   the cost of the goods to which each interest originally attached bears
   to the cost of the total product or mass.
