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