Ketonic Resin Basic Facts

• Ketonic Resin are also known as
• POLYKETONE
• KETONE ALDEHYDE RESIN
• KETONE FORMALDEHYDE RESIN
• CYCLOHEXANONE FORMALDEHYDE RESIN
• Some Basic Facts
• Not functional in Water Based products.
• It can be used BASE Resin
• It can be used a BINDER
• Its used as ADDITIVE or ENHANCER or
  MODIFIER in formulation
• It turns yellow with time due to oxidation
• It is hygroscopic (attracts water)

About Polyurethane/PU

• About Polyurethan (PU)

• Developed by Otto Bayer in 1937
• Produced as Elastomers, Foams, Coatings,
  Adhesives Fibers, Synthetic Leather etc
• PU industry shown significant growth in adhesives
  and coatings
• Normally consists of Polyol (Polyester or
  Polyether Type, Isocynate additive
• Property depends on Stoichiometric proportions of
  types of isocynates polyols
• Oldest Type are 1-component PU system based on
  di- or triisocyanates that cured by reacting
  with active hydrogen on substrate or moisture

Typical Polyols Typical Isocyanate

About Polyurethane/PU

• Before we get too Technical! Basic of
  Polyurethane (PU System)

• Its a 2 Component System it needs two
  reactants to make a PU
• PU can be Foam, Coatings, Adhesives, Fibers etc
• When they say it is a 1 component system
• Moisture (water) plays the part(role) of the
  POLYOL
• There are different types of Polyols
  Isocyanates
• Choice of these different types determine the
  property
  
  of the final PU
• The Reactive Sites or Groups in the Polyol
  Isocyanate
  reacts to produce the PU

About Polyurethane/PU

• Before we get too Technical! Basic of
  Polyurethane (PU System)

• Where does Ketonic Resin come into the picture
• Ketonic resin can be mixed with Polyol and
  reacted with Isocyanate
• KR can be made into solution (e.g.mixed in
  chloroform) and reacted
• The solvent shall be needed to be removed by
  vacuum
• Because KR has the same Reactive Site/Group as
  a Polyol
• It blends easily with Polyol
• It reacts easily with Isocyanate
• It gives enhancement in the overall property of
  the PU
• Basically its an additive which provides multiple
  benefits

Properties of KR and its effect on PU
Melting Point or Softening Points determines the
HARDNESS. Higher Melting Resins also provides
Higher Gloss

Viscosity determines the flow and leveling
properties
Measure of the Reactive Sites. Determines how
much the KR shall react with the Isocyanate of
the PU. Formulator can ask for Higher or Lower
OH value
KR are NEUTRAL resins hence its negligible Acid
Value does not affect the PU or Substrate

PU Systems with Ketonic Resin

• KR interaction with PU System

16
PU Systems with Ketonic Resin

• KR interaction with PU System

• Resins such as POLYTONE K 96 and POLYTONE K 97
  contain a high level of hydroxyl groups that
  makes it particularly suitable for combined use
  with polyols and isocyanates in the formulation
  of bicomponent polyurethane systems (PU or PUR
  2K).
• Our Ketonic resins react easily with mono and
  di-isocyanates, such as HDI, TDI, MDI and IPDI.
• The strong bond created by hydroxyl group and
  isocyanates guarantees a strong resistance to
  water, heat and corrosion.
• This technology is used in a wide variety of
  applications including indoor and outdoor floors
  (for example industrial plants, warehouses,
  garages, car parks, etc.) as well as roofs.
• The almost infinite possibility of combining
  colours and patterns makes these systems
  particularly suitable for finishing floors in
  designer shops and houses, where the only limit
  is the designers imagination.

Benefits of KR in PU Systems

• Ketonic Resin in Polyurethane POLYTONE? K
  Series

Why Use Ketonic Resin? What is the effect and/or How it imparts?
As a Carrier or Binder Links with Polyol and reacts with IsoCyanide
As Flow Modifier -OH Value reacts and increases viscosity
Corrosion Prevention Low Acid Value
Color Fastness Binding Property-Binds PigmentSolvent
Adhesion, Gloss Improves Adhesion to substrate
Increase Solid Content Resin is solid
Leveling Inherent Property
Hardness Inherent Property
Gloss KR inherent property of gloss is imparted
Thermal Resistance KR increases Thermal Resistance
Green or Build Up Strength KR increses
Reduce NCO Excess IsoCyanide is consumed by KR
