  2. Waterborne plastic coatings by Magdalena Bodi

  3. Alberdingk Boley 178 years History • Production of oils (linseed and castor) • Start with WB binders: Acrylic dispersions 1985Polyurethane dispersions • Production of adhesives • Alberdingk Boley Inc., NC, USA • Production in Greensborough, USA 2006 Alberdingk Boley in China

  4. Alberdingk Boley Contents • Company introduction • Binder types, characteristics, film formation • Application field plastic coatings Required properties Product recommendation

  5. Waterabased dispersion? Waterbased emulsions? Latexes? Solutions in water? Small solid polimer particles dispersed in water = DISPERSIONS m.w.>100000 Dilutable with water in liquid fase Non soluble in water as a dried film Alberdingk Boley Nature of AB dispersionsWhat are really this binders??

  6. Particle size: > 1µm: milky white 1µm – 0,1µm brownish white appearance 0,1µm - 0,05µm semi-transparent < 0,05µm almost transparent Alberdingk Boley Optical appearance of the dispersion Acrylic PUD PUD

  7. Alberdingk Boley Stage I Evaporation ofwater Stage II Particle deformation, T > MFFT Stage III Coalescence Stage IV Interdiffusion of polymer chains Film forming mechanism • Aqueous polymer dispersion(Solid Content: 30-60%) • Arrangement of particles, close contact • Deformation of the polymer particles • Surfaces of polymer particles are disappearing: polymer chains intermix • Polymer interdiffusion, leading to a mechanical stable polymer film

  8. Alberdingk Boley MFFT reduction with different coalescing agents for AS 2615 MFFT °C Cosolvent %

  9. Alberdingk Boley Curing mechanisms of w/b coatings • 1-Component (drying only) optional: self cross-linking binders • 2-Component cross-linking • UV cross-linking • Dual curing (UV and isocyanate)

  11. Alberdingk Boley Application fields • Hifi , TV-Sets , Mobile phones, Computers, etc. • Car interior : different plastic parts, softfeel and non- softfeel • Car exterior: Basecoats Wheel cover

  12. Alberdingk Boley Requirements Very good adhesion Alu-pigment orientation Alcohol- und fat resistance Scratch resistance Substrates : ABS , PS ABS-PC, PC

  13. Mobile phones Recommended products: Styrene-Acrylic dispersions: AS 2615, AS 2606 good chemical resistance, hardness Polyurethane dispersions: U 9160 or U 9800 as 2K systems for excellent chemical resistance and hardness

  14. Alberdingk Boley Computer-, TV, HIFI casesProduct recommendation Styrene-Acrylics: AS 2615; AS 2606, basecoat, monolayer OH-functional acrylics: AC 2598; AS 2799 as 2K-PU PU binder: U 9160, U9800 as 2K-PU

  15. Alberdingk Boley Finish possibilities 1K paints and lacquers AS 2606, AS 2615as basecoat or multilayer Good chemical resistance, hardness 2K paints and lacquers U 9800, U9160, PU binder as base- and topcoats, excellent chemical resistance, hardness AC 2598, AS 2799, AC binders as base-and topcoats, very good chemical resistance, excellent hardness

  16. Paint components: Binder Cosolvents Water Defoamer Alu pigment Substrate wetting additive Rheological additives Recommended parameters: Solid content: Basecoats: 15-25% Monolayer: 25-35% Chromeffect: 5-10% Cosolvents: AS types: ca. 20% cosolvent on total formulation Alu-Pigment: Alu pigment concentrate! Alberdingk Boley Aluminium pigmented formulation based on AS 2615, AS 2606

  17. Alberdingk Boley Type of Aluminium Pigments (Shape) Stronger light scattering, more edges Less metalic effect, more gray colour, Corneflakes, smaller particle size, wide particle size distribution Cornflake Stronger light reflexion, more brilliant colour Silverdollar, rounder shapes Narrow particle size distribution Silverdollar

  18. Alberdingk Boley Type of Alu Pigments (Surface treatment) Possible surface treatments : • Phosphororganic, pigment preparation only with water, excellent binder compatibility • Water + Solvent: Pigment preparation+ BG and PM • fair good gasing stabiliy • Chromate , excellent continuous gasing stability, condens water stability, intercoat adhesion • Anorganic SiO2-Treatment, Sol-Gel Process, higher whiteness, v.good orientation, shearing stress and excellent gasing stability,intercoat adhesion, circular pipe line stability

  19. Alberdingk Boley Pigment orientation • Good pigment orientation • High gloss, brilliance • High hiding power • Bad pigment orientation • "Salt-and-Pepper” Effekt Recommended rheological additives for good pigment orientation: Acrylic thickener: Viscalex HV 30(Ciba), Latekol D (Basf) Antisettling additives: Byk-420 (Byk), Disperlon Q-607, etc.

  20. Alberdingk Boley Alu Pigment preparation Premix Aluminium Pigment concentrate with: Water/BG(1:1) + Additive Possible Additives: Dis-190 for organic traeted- Dis-180 or TegoWet 655 for inorganic treated pigments Dosage: 5-8% on Alu-Solid content Important to avoid high shearforcess!

  21. Alberdingk Boley Car interior coatings Substrates mainly: PA 6 , ABS-PC, PP Requirements : Very good adhesion Scratch resistance Alcohol and Fat resistance Feel between velvet and rubber for softfeel coatings

  22. Alberdingk Boley Car interior coatings Product recommendation Softfeel: Polyurethane dispersions :U 610 , U 2101 , CUR 21 Acrylic dispersions: AC 2592, AC 2597 and their combinations! Hard plastic: Acrylic dispersion: AS 26090!! NEW! Bodi

  23. Alberdingk Boley Car interior coating; Softfeel paints For good chemical and mechanical resistance softeel paints should be 2K systems! • Recommended Hardeners: • Hydrophylic Isocyanates : • Bayhydur 2306; Bayhydur 3100 • Bayhydur 2336 • Basonat HW 100; Basonat HW 180PC • Rhodocoat WT 2102, Rhodocoat 803

  24. Car outside / Basecoats • Requirements: • Excellent adhesion • Recoatability • Clarity , brilliance • Good Alu pigment orientation

  25. Alberdingk Boley Car outside/ Basecoats Product recommendation: Polyurethane dispersions : U 3251 , U 610 ( 1 and 2 K systems) Polyurethane-Acrylic dispersion : APU 10120 (1 and 2 K systems) For 2K systems crosslinking with hydrophilic isocyanates Bodi

  26. Alberdingk Boley 2-Komponent wb lacquer 1-K: OH functional acrylics Crosslinkable groups containing PU binders 2-K: Hydrophilic, aliphatic isocyanates Commercial Types from BASF, Bayer, Rhodia Silanes Carbodiimides

  27. Alberdingk Boley 2-Component w/b lacquer • Benefit of crosslinking: similar to s/b systems: improved chemical properties better adhesion increased abrasion resistance • Disadvantage : short pot life limited storage needs more attention

  28. Alberdingk Boley PVC- Window frames • Requirements: • Excellent adhesion • Water resistance • Very good blocking resistance • Good pigment wetting

  29. Alberdingk Boley PVC- Window frames • Product recommendation : • PU- AC dispersion : APU 10610 • Combination with AC 2508 for blocking resistance improvement possible

  30. Alberdingk Boley Adhesion on difficult substrates

  31. Alberdingk Boley Adhesion on difficult substrates Possibilities to work with adhesion promoters: • Use adhesion promoters as a separat primer • Add adhesion promoters directly to the primer as a paint component – more convenient- e.g. in formulations based on AS 26090 we can add: 10-20% CPO 347W(Eastmann)

  32. Alberdingk Boley Targets for the future • Low solvent containing and solvent free binders • Generally lowering of VOC • Chemical resistance improvement • Increasing of adhesion and scratch resistance • Easy to formulate binders
