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
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
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
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

summary of issues on approaches to lower voc 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
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
