Item 1.

Security and Issuer.

This Amendment Number 3 (“Amendment No. 3”) to the Schedule 13D originally filed by SNPE, Inc., SOFIGEXI, and SNPE (collectively, the “Stockholder”), relates to the Common Stock, $.05 par value (the “DMC Common Stock”), of Dynamic Materials Corporation, a Delaware corporation, (the “Issuer”). The address of the principal executive offices of the Issuer is 5405 Spine Road, Boulder, Colorado 80301. This Amendment No. 3 is being filed to reflect certain changes to Items 4, 5 and 6.

Item 4.

Purpose of Transaction

On June 14, 2000, SNPE, Inc. and the Issuer consummated a Stock Purchase Agreement dated as of January 20, 2000, pursuant to which SNPE, Inc. purchased 2,109,091 shares of DMC Common Stock for approximately $5.8 million (the “Purchase”), giving SNPE, Inc. control over the Issuer. In addition, in connection with the Purchase, SNPE, Inc. purchased from the Issuer a five-year, 5% Convertible Subordinated Note (the “Note”), convertible in whole or in part into DMC Common Stock by SNPE, Inc. at a conversion price of $6 per share, with an aggregate principal amount of $1.2 million. On June 20, 2000, SNPE, Inc. purchased an additional 248,000 shares of DMC Common Stock for an aggregate purchase price of $405,480 in a privately negotiated purchase. On June 8, 2005, the Note was converted into 200,000 shares of DMC Common Stock.

Prior to the Purchase, in December 22, 1999 SNPE, Inc. acquired 406,400 shares of DMC Common Stock from Nobel Explosifs France, another wholly-owned subsidiary of SNPE, at a price of $1.44 per share, in a transaction executed for internal accounting purposes.

On October 5, 2005, the board of directors of the Issuer effected a 2 for 1 split of the DMC Common Stock (the “Stock Split”). After giving effect to the Stock Split, the Stockholder beneficially holds an aggregate of 5,926,982 shares of DMC Common Stock.

The Stockholder is currently exploring the sale of up to all of its shares of DMC Common Stock in an underwritten secondary offering. The Stockholder is evaluating the opportunity and has engaged in discussions with the Issuer and potential underwriters in connection with such a sale. The Stockholder intends to relinquish control of the Issuer and fully liquidate its equity interest in connection with such an offering. The stockholder has not entered into any binding agreements or arrangements in connection with such potential sale.

Item 5.

Interest in Securities of the Issuer.

(a) After giving effect to the Stock Split, the Stockholder beneficially holds an aggregate of 5,926,982 shares of DMC Common Stock. This position currently represents 50.4% of the 11,758,920 shares of DMC Common Stock currently outstanding.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

There are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 1 of this Amendment No. 3, and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of
