New HS Acrylic Resins for
industrial use
ECS Nuremberg
2013
Ad van Gaans
Introduction Nuplex
 A leading independent chemicals company
 Global presence: manufacturing operations in Europe, Asia, America,
Australia and New Zealand
 Products serving a wide range of end markets including automotive OEM,
vehicle refinish, aerospace, industrial, protective, marine, decorative
paint, industrial wood, flooring and construction, adhesives, inks, paper
and textiles industries.
 Two business segments:
• Nuplex Resins − global independent resins producer
• Nuplex Specialties − Australasian trading and agency business for
specialty chemicals
2
Changes in the industrial coatings market
EU legislation leads to changes in solvent use
 Low Solids  Medium Solids  High Solids
 Solvent Containing  Solvent Free
 Solvent Borne  Water Borne
3
Consequences of using water borne two-component
polyurethane paints
 Different binder architecture
(can also apply to the hardener)
Or use a lot of surfactants
 More complex process
 Polar groups for stabilization
 More expensive
 Water is not an ideal solvent
 Biocides
 Stainless steel equipment
 Water is also a co-reactant (NCO)
 Storage stability
 Relatively high freezing point
 Relatively low boiling point
 Hydrolysis
Water is a far from ideal solvent!
4
Consequences of higher solids
Increase solids content
 Viscosity goes up
 Poor appearance
Why still prefer high solids over water borne?
High solids paints are closer to conventional low and medium solids in:
 Ease of formulation (solvents)
 Application, film formation
 Cost structure (no / little investment needed)
But then we must increase resin solids content
without increasing viscosity
5
What will determine resin viscosity?
Viscosity: ‘liquid friction’
Ease of movement of molecules along each other is influenced by:
 Molecular size and shape in the solvent
• Hydrodynamic volume
• Molecular weight data from Size Exclusion Chromatography: Mn, Mw
 Polymer architecture (free volume): is related to Tg
 Additional friction from hydrogen bridges
• OH concentration (OH-value)
• OH exposure (OH-type, steric hindrance, bulky structures)
 And other polar interactions
6
Molecular weight
Lower molecular weight provides:
Lower VOC content
Higher flexibility
Better compatibility
Higher gloss
Better filling power
But also:
 Lower hardness
 Lower chemical resistance
 Lower water resistance
 Lower durability
Lower hydroxyl functionality will result in a lower crosslink density!

Design of high solids acrylic polyols
 Designing good high solids polyols requires in-depth understanding of all
aspects of polymer physics and polymer chemistry
 At Nuplex we have used all our know-how and design tools to develop
the best high solids acrylic polyols, not only for use in industrial,
protective, and marine coating applications, but also for the demanding
automotive and refinish markets
 We meet new challenges by pushing the limits of resin design further
again, often in close cooperation with our customers and co-suppliers
