AEROSOL ADHESIVESAND AMREP A Brief Overview of History, Chemistry and Issues Presented to the California Air Resources Board 11/8/99
Who is Amrep? • One of the largest manufacturers of both branded and private label chemical programs in the USA • Marketer to the Industrial and Institutional, Automotive Aftermarket, Water Treatment, and Consumer Products/Retail business segments • Not a contract filler -- we provide programs to our customers competitively and at values exceeding alternate sources of supply on a total turnkey basis • One of the few manufacturers who can truly be a “one stop shop” for many distributors and retailers with aerosols, liquids, and lubricants in the product line
History of Amrep The business began independently as: • Aero Mist, founded in 1969 as an aerosol manufacturer in Atlanta, GA • Research Products, founded in 1960 as a bulk liquid manufacturer in Dallas, TX Aero Mist and Research Products merged in 1979 to form AMREP • Arrow Grease and Oil of Dallas, TX was acquired in 1987 adding a complete line of lubricants • MBL Industries of Santa Ana, CA another aerosol manufacturer, was acquired in 1987 completing the acquisitions to date
The Environmental Amrep • We have been recognized by the Environmental Protection Agency as a successful participant in the 33/50 Program -- a voluntary reduction of emissions at all of our manufacturing plants • We were one of the first companies to enable their customers to comply with the 1991 Clean Air Act by providing alternative products to chlorinated solvents and other ozone depleting substances • We currently offer only two products with any ODP (HCFC 141b) and will phase out methylene chloride in 2000 • We utilize an on site, state-of-the-art waste stream reduction system reduce hydrocarbon waste and emissions - an industry first • Our packaging is made from recycled material containing, recyclable, components
Capabilities - Aerosols • 140 stocked aerosol formulas for institutional, industrial, and consumer applications • Marietta, GA facility is 150,000 sq..ft. with 2 high speed rotary fill and 1 in-line fill production lines • 2000 capacity is approximately 45-50 million cans • Equipped for natural hydrocarbon and synthetic liquefied gas propellants as well as all compressed gas propellants but not equipped for DME (safety, setbacks) • Aerosol adhesives comprise over 10% of sales and is the largest single product category for AMREP
Seven formulations are offered each for a specific technology and/or application All are solvent based nonchlorinated with hyrdocarbon propellant PS Repositionable Mist PS HD General Purpose Mist PS LD General Purpose Mist PS LD General Purpose Web PS HD General Purpose Web PS HD Foam and Fabric Web High Heat Trim Web Contact Cement AMREP Aerosol Adhesives

Summary of Issues on Approaches to Lower VOC Aerosol Adhesives • Higher Solids - limited feasibility due to sensitivity of spray patterns, mechanical capabilities of valves, solubility sensitivity • Higher non-VOC Solvent Content - lack of availability, impact on dry time, cost, performance, and solubility concerns • Higher non-VOC Propellant Content - availability concerns, cost impact, greater solubility issues than hydrocarbons • Leading Edge Materials - position on acceptability and availability not definitive enough for 2002 implementation • Conclusions?
Conclusions • VOC LEVELS LOWER THAN 60%-50% • REQUIRE EXTENSIVE RESEARCH FOR THE DIFFERENT CATEGORIES OF ADHESIVES (SOME MORE DIFFICULT) • MOST LIKELY NOT COST EFFECTIVE FOR MANY CATEGORIES • MAY NOT MEET GENERAL PERFORMANCE REQUIREMENTS • MAY INVOLVE “HAZARD TRADING”: LOWER VOC FOR ????? • LEVELS MAY NOT BE POSSIBLE FOR ALL APPLICATION AREAS • BELOW 25% LIKELY NOT ACHIEVABLE FOR ANY AREAS UNLESS BREAKTHROUGH MATERIAL IS AVAILABLE • WATER-BASED SIMPLY NOT AN OPTION IN AEROSOL
