Why is it common to use too much adhesive
? Often because we have blocked nozzles from
system CHAR. So We increase the size
of nozzles

350oF Exposure Test

Adhesives that are more viscosity stable and
resist charring. Both avoid having to increase
nozzle size and change system pressure.

As we move up the value / performance grid, what
benefits do we achieve?...

Adhesives that cut off cleanly rather than
produce a tailing effect. Clean cut-off means
less clean up, less downtime and less adhesive
consumed.

As an adhesive user, you have the ability to

• Achieve lowest total cost of ownership
• Minimize internal and external costs. 10-40
  savings are typical and achievable.
• Increase Mileage
• 10-35 mileage advantage is attained through
  lower density, thermal stability, precise
  application and aggressive bonding.
• Reduce Line and Maintenance Costs
• Eliminate char. Less nozzle, module hose
  replacements. Reduces line, tank and cleaning
  costs.
• Increase Plant Yield and Throughput
• Reduced downtime and rejects. Fast speed of set
  yields maximum line speeds.
