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
AMREP Aerosol Adhesives
Seven formulations are
offered each for a
specific technology
and/or application
All are solvent based
nonchlorinated with
hyrdocarbon propellant

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
