Powder Coating Technology Update
  HAA (non-TGIC) technology
  Premium weathering products
  Antimicrobials
  Thermoplastics
  Agriculture and construction equipment (ACE) market
HAA (non-TGIC) and
Premium Weathering Formulations
HAA (Non-TGIC) Polyester Technology
  Technology driven by 1) regulatory concerns regarding
TGIC resins in Europe, and 2) global shortage of IPDI
crosslinking agent
  Non-TGIC polyester powders formulated with a
beta-hydroxyalkyamide (HAA) crosslinking agent
(sometimes referred to by the trade name, Primid®)
  Improved weathering over standard polyesters
  Excellent transfer efficiency compared to typical
polyesters
  Globally accepted as a non-mutagenic and non-toxic
classification (no special labeling)
Premium Weathering Polyesters
•  Designed with superior weathering capabilities, i.e., they retain
gloss and color longer than traditional TGIC polyester, urethane
and non-TGIC powder formulations.
Premium Weathering Polyesters
  Performance dependent upon pigments, resins, curing
agents, and other additives that can improve resistance
to fade.
  A product labeled as premium weathering does not necessarily
conform to any AAMA or Qualicoat standard.
 Note: Remember when specifying powder coatings, provide
detailed performance requirements such as hours of salt
spray resistance, hours of weathering resistance per a
known test method, such as ASTM.

Why Do We Need
Antimicrobial-treated Products?
"

"
Microbes can interfere with performance or cause
functional problems such as:
o  odor
o  growth of bacteria, mold, and mildew
on surfaces
Cross contamination of surfaces is a challenge
Controlling the growth of bacteria is a growing
concern for many industries
o  Healthcare and healthcare construction
o  Food industries
o  Water-related industries
o  Textiles
o  Consumers
Why Do We Need
Antimicrobial-treated Products?
  Most of our time is spend indoors
  More people work in offices than ever before
  We travel more than ever before
  We spend less time cleaning than the last generation
  We are less clean (e.g., laundry practices)
  We spend more time in public places
  Public places are larger than ever before (cruise ships, office
buildings, stadiums, etc)
  We are more mobile and have more electronic equipment
(e.g., cell phones)
Conclusion – we share more fomites than ever before
Dr. Charles Gerba, University of Arizona
Did You Know . . .
That the average office keyboard has 500 4mes more microbes than a toilet seat ?
Why Do We Need
Antimicrobial-treated Products?

Why Do We Need
Antimicrobial-treated Products?
Mechanism: Cross-Contamination
Cross-contamination – TOUCH TRANSFER
•  Examples: Door knobs, keyboard, cutting boards
•  Problem: The surface serves as a microorganism
transfer site through regular contact with people
or objects

Why Silver?
Long recognized as effective against bacteria
  79 AD – Egypt - Long-term water storage
  900s – China - Emperor used only silver for
eating “to prevent poisoning”
  1880 – Crede’s prophylaxis for infant eye drops
  1800s – “Born with a silver spoon…”
  1960s – Silver compounds begin to be used in
burn wards
  2000s – Agion antimicrobial used for “in body”
medical devices (e.g., catheter)
Modern Examples in Uses of Silver
  Burn treatment bandages and salves
  Catheters
  Heart valve suture rings
  External fixation pins
  Over 58 FDA-approved silver-based products
