Dyneon Announces Expansion Investment for Dyneon™ Scotchshield™ Film 17

St. Paul, Minn (August 27, 2008) - Dyneon LLC, a subsidiary of 3M Company, is investing in additional capacity for its Dyneon™ Scotchshield™ Film 17, a backsheet for c-Si photovoltaic (PV) solar modules, due to tremendous demand for the product. The new manufacturing capacity will be located in Singapore, as part of a previously announced $200 Million investment by 3M in film production. Co-location with other 3M film businesses provides benefits from shared resources and infrastructure.

Construction of the facility has already begun, and product from the facility is expected to be available early 2010 or sooner. The Dyneon™ Scotchshield™ Film 17 made at the new site will utilize the same production technologies and experience gained during 40 years of high volume film production to maintain the same exacting specifications of the current product.

Dyneon™ Scotchshield™ Film 17 utilizes a sophisticated multi-layer construction consisting of an outer fluoropolymer film bonded to a proprietary PET film which is bonded to EVA film to complete the multilayer backsheet. This inner EVA layer of the backsheet bonds to EVA cell encapsulants during the PV module lamination process. Real world experience in the PV module industry has validated the value of utilizing proven materials and technologies. The product is sold and supported globally through a network of Dyneon and 3M sales and technical personnel.
