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

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?

18
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
