INTRODUCTION

1.1. Introduction
IROSTIC is Huntsman's trade name for a
polyurethane-based raw material for the
manufacture of TPU adhesives. IROSTIC has been
produced by Huntsman GmbH in Osnabrück for 27
years and are available with a broad range of
base polyol and isocyanate chemistries. IROSTIC
systems can be used as a one-component or
two-component system with the IRODUR
cross-linkers. The product range is available
world-wide in a range of packaging sizes.

SOLUTION GRADE ADHESIVES

1. 2. Technical Information

• IROSTIC adhesive systems should be dissolved in
  closed dissolvers. The time required depends on
  the solvent used and on the construction features
  of the equipment. It is recommended to strain the
  finished solution. If fillers have been added to
  the system then added straining may be essential.
• The adhesive solution may be applied to the
  prepared (roughened, solvent wiped) surface
• Manually via brush, roller, spatula
• Mechanically via roller, knife, spray gun or air
  gun
• The adhesive surface should be applied onto both
  surfaces. The surfaces are then air dried until
  the solvent has evaporated. Depending on the
  quantity applied this takes between 30-60
  minutes. A frequent cause of poor adhesion is
  insufficient drying. The dry surfaces are then
  pressed together following the required
  activation procedure to obtain a stable bond.
• IROSTIC adhesives can be reactivated. After
  drying the film is simply reactivated by heat. If
  used as a two-component adhesive reactivation
  must be carried out within a 6-12 hour period.
  Reactivation takes place under infrared light
  (50-80deg C) for approximately 1 minute.
• Where IROSTIC is used as a two component
  adhesive, the pot life must be taken into
  account. Even at room temperature the
  cross-linking reaction starts the moment the
  cross-linking agent is added to the adhesive
  solution. The viscosity of the solution gradually
  increases until, after 8 to 12 hours, the
  adhesive has solidified beyond spreading
  consistency.

1. 3. Storage Information
All products must be stored in a cool and dry
place. Under adequate conditions a minimum
stability of 6 months may be expected.

1. 4. Solvent Systems

• The choice of solvents is of great importance
  since both evaporation rate and viscosity of the
  finished adhesive are linked to the solvent used.
  The following solvents may be used
• Ketones
• Acetone, Methyl ethylketone (MEK)
• Ester
• Methylacetate, ethylacetate, butylacetate
• Aromatics
• Toluene
• Toluene may be used in combination with many of
  the solvents described above and detailed
  information is available for each of the
  individual grades with various solvent blends.
  All solvents used should be free from water and
  alcohol (below 0.1). The viscosity of IROSTIC
  solutions increases if instead of ketones, esters
  or toluene is used. At the same solids content a
  low viscosity is obtained in ketone solvents
  (MEK, acetone) medium viscosity in blends of
  ketones / esters and high viscosity in blends of
  ketones and aromatics.

15 solids in a range of solvent blends

MELT ADHESIVES
TM
2.1. Technical Information

• Hot melt adhesives are solvent-free adhesives
  that are characteristically solid at room
  temperature and are low viscosity fluids when
  melted and then rapidly set upon cooling. The
  development of hot melt adhesive technology
  stemmed from the previous use of molten wax for
  bonding.
• It is possible to use TPU resins in formulation
  of a range of hot melt materials to provide a
  range of formulation opportunities to extend the
  performance of other resin technologies.
  Typically, in addition to the base hot melt
  polymers a variety of tackifying resins, waxes,
  antioxidants, plasticizers, and other materials
  can be added to the adhesive formulation to
  enhance the polymer performance.
• Industry Applications of Hot Melt Adhesives
• Laminating adhesives
• Bonding of woven / non-woven fabrics
• Manufacture of athletic shoes, books, and
  sporting goods
• Manufacture of packaging materials
• Aerospace and automotive assemblies

2.2. Application
Hot melt adhesives form a strong bond quickly
simply by cooling and are compatible with most
materials, and are clean and easy to handle. In
general, hot melt adhesives are less water
sensitive than other thermoplastic polymers, and
are unaffected by water, moisture, or humidity,
although if applied to a damp or wet surface the
bonding may be poor. Hot melts can be
formulated to increase their water sensitivity,
as when used for stamps, envelopes and paper
products that are to be recycled. Hot melt
adhesives also have some limitations that must be
recognized. Hot melts cannot be used with heat
sensitive substrates the adhesive bonds lose
strength at high temperatures chemical
resistance may be lacking with some types of hot
melts and exposure to high temperature
environments can cause the adhesive to melt.
Consequently, hot melt adhesives are
inappropriate in situations where these
limitations cannot be avoided.
