Raytheon Systems Company Lowering VOCs in the Application

Raytheon Systems Company Lowering VOCs in the Application of Weapons Systems Coatings Kelly Eddings May 26, 1999 1

Goal • Reduce Volatile Organic Compounds(VOCs), and Hazardous Air Pollutants (HAPs) in Painting and Coating Materials • RSC-wide Application (“Design Anywhere, Build Anywhere”) 2

Steps to Achieve Goal • Step I – JG-PP Effort which accomplished two (2) SPIs for the Use of Alternative Materials for High VOC coatings. • Qualification of Powder Coating which passes CARC testing. – Consolidated Previously Submitted or Approved Legacy SPIs – Standardized Test Protocol to Validate Alternative Primers and Topcoats 3

Steps to Achieve Goal • Step II – No paint, Primer Only, Decals and Appliques (This effort being lead by Raytheon Missile Systems in Tucson). 4

Steps to Achieve Goal 4 Intermediate Step Implementing CO 2 Technology 5

Why CO 2 Technology as an Intermediate Step? • Our VOC emissions must be lowered prior to Phase II completion (12/2001). • CO 2 Technology can be implemented within a reasonable time span. • Ability to apply a broad spectrum of coating types. 6

Benefits • • Compliance with State Air Emissions/Restrictions (TX) Decrease coating application time Less Material Needed for Coating Process Reduction of Potential Employee Exposure Reduction of Chromium Releases Reduction of VOC emissions Reduction in Health/Safety Compliance Costs Increased Operating Flexibility 7

Targeted Materials for Identification of Alternate CO 2 Compatible Material/Process MIL-P-23377 MIL-PRF-85582 MIL-C-22750 MIL-C-46168 MIL-PRF-85285 8

Actions • Identify Availability of Alternatives • Interest of other Defense Contractors • Funding Source? • Coating/Paint Suppliers • Involvement of Union Carbide and CTC • Testing of Material • Qualification/Acceptance Criteria 9

• Activity Status: – Initial study conducted at the Union Carbide Research Technology Center in Charleston, West Virginia. • Results • Ability to achieve coating build-up/thickness in approximately 1/3 of the time. • Decreased the VOC content of the coating from 3. 35 lb/gal to 1. 36 lb/gal. 10

• Activity Status Continued: – Conducted Transfer Efficiency Study at CTC on May 25, 1999. • Comparison of CO 2, HVLP, and Airless Application Methods. • Results – All results have not been calculated at this time. • Confirmed Results – Decrease in time to achieve film thickness – Decrease in VOCs – Improved Distribution of Droplet Size 11
