1、 METRIC A-A-59785 9 DECEMBER 2005 COMMERCIAL ITEM DESCRIPTION EPOXY COATING KIT (EPOXY RESIN SYSTEM) The General Services Administration has authorized the use of this Commercial Item Description by all federal agencies. 1. SCOPE. This commercial item description (CID) covers a two part epoxy resin
2、system suitable to be used in the production of advanced composite materials. 2. SALIENT CHARACTERISTICS. 2.1 General. The Epoxy Resin System is a two component resin system for use in the production of advanced composites. The two components include the epoxy resin and a hardener used for curing th
3、e final product. When the two parts (resin and hardener) mix together, they react, and join together. The advanced composite manufacturing infusion processes in which the described Epoxy Resin System could be used include Resin Transfer Molding (RTM), Vacuum Assisted Resin Transfer Molding (VARTM),
4、Seemans Composite Resin Injection Molding Process (SCRIMPTM), prepreg hand lay-up, and/or other infusion processes. The manufacturers formulated mix ratio, measuring out by weight and volume, shall be followed to ensure the complete reaction of the resin and hardener. 2.1.1 Performance Requirement.
5、Unless otherwise noted, the epoxy resin system shall meet or exceed the performance criteria in Table I. when tested at 77F (25C). TABLE I.

The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 4. PRODUCT CONFORMANCE. 4.1 Product Conformance. Th
11、e products provided shall meet the salient characteristics of this Commercial Item Description, conform to the producers own drawings, specifications, standards and quality assurance practices and be the same product offered for sale in the commercial marketplace. The government reserves the right t
12、o require proof of such conformance. 4.2 Market Acceptability. The product shall be a standard commercial item or a modified commercial item to minimize design and engineering risk. A commercial item is required to ensure serviceability, reliability and quality of materials. Bid samples may be requi
13、red for the Epoxy Resin System to ensure product quality. 5. PACKAGING. Preservation, packaging, packing and marking shall be specified in the contract of purchase order.
